Given function: f(x) = −1 + 0.5x
We have to find the value of x does f(x) = 2.
For this, we put the different values of x and see what value satisfies the given function.
For x = -6
f(x) = −1 + 0.5(-6)
f(x) = -4
For x = 5
f(x) = −1 + 0.5(5)
f(x) = 1.5
For x = 6
f(x) = −1 + 0.5(6)

Two friends, Andrew and Liz, are playing a game using this spinner. If the spinner lands on region 1, Andrew wins. If it lands on region 2, Liz wins. If it lands on region 3, nobody wins. Is this a fair game?
Answer:
Based on the information provided, it does not seem like this game is fair. Since region 1 and region 2 are the same size, each player has an equal chance of winning, but since region 3 is significantly larger than the other regions, neither player has a high chance of winning. This means that one player could potentially win multiple times in a row just by luck, without the other player having a chance to catch up. In order for the game to be considered fair, the relative sizes of the regions should be such that each player has a roughly equal chance of winning.
Answer:
yes. they both have ⅓ chance of winning

Answer:
a= 108 degrees
b=88 degrees
c= 90 degrees
d= 90 degrees
Step-by-step explanation:
For a degrees since 72 degrees and a degrees make a straight angle:
180-72= a
So, a=108 degrees
Same goes for b degrees:
180-92=b
So, b=88 degrees
For c degrees, you need to know that the sum of the angles in a quadrilateral equal to 360 degrees.
So, 74+a+b+c=360
= 360- (74+108+88)=c
= 90 degrees= c
So since d degrees and c degrees make a straight angle,
180-90=d
90 degrees= d

N
H

B
32-1
D
Step-by-step explanation:
To make the equation AFGHACBD true, the value of y must be 7, and the value of z must be 32-1=31.
Here is how the equation works out:
2z + 14 = 2 * 31 + 14 = 68
2y + 35 = 2 * 7 + 35 = 49
68 + 2 = 70
70 > 49
49 + 7y = 49 + 7 * 7 = 98
98 > 70
70 + 32 - 1 = 70 + 31 = 101
101 > 98
98 + 2y + 35 = 98 + 2 * 7 + 35 = 146
146 > 101
So, the values of y and z that make the equation AFGHACBD true are y=7 and z=31.

0.87; There is a strong, positive association between discharge and speed.
−0.76; There is a strong, negative association between discharge and speed.
−0.87; There is a strong, negative association between discharge and speed.
Answer:
The value of the correlation coefficient is 0.87, which means there is a strong, positive association between discharge and speed. A positive correlation means that as one variable increases, the other variable also increases. In this case, as the discharge of the Colorado River increases, the speed of the river also increases. The strength of the association is indicated by the magnitude of the correlation coefficient, which ranges from -1 to 1. A value of 0.87 is considered a strong positive correlation, indicating that there is a strong relationship between the two variables.

How to find the slope between two coordinates?
The formula for the slope between two coordinates is;
Slope = (y₂ - y₁)/(x₂ - x₁)
Let us take two coordinates from the table which are;
(2.4, 7.2) and (4.5, 13.5)
Thus;
Slope = (13.5 - 7.2)/(4.5 - 2.4)
Slope = 3
Now, looking at the options, the first 3 cannot be correct because they have mixed up x-coordinate values with y-coordinate values.
Let us check the last option which is a line that goes through (0, 0) and (4.5, 13.5). Thus;
Slope = (13.5 - 0)/(4.5 - 0)
Slope = 13.5/4.5
Slope = 3
Thus, we conclude that it is correct.

An insurance company is reviewing its current policy rates. When originally setting the rates they believed that the average claim amount was $1,800. Now there are concerns that if the true mean is actually higher than this they could potentially lose a lot of money. They randomly select 40 claims, and calculate a sample mean of $1,950. Assuming that the standard deviation of claims is $500, and set significance level = :05, test to see if the insurance company should be concerned.
So, the insurance company should be concerned that they could potentially lose money.
To test whether the insurance company should be concerned about the true mean claim amount being higher than the original estimate of $1,800, we can perform a one-sample t-test.
The null hypothesis for this test is that the true mean claim amount is equal to the original estimate of $1,800, and the alternative hypothesis is that the true mean claim amount is greater than the original estimate.
The t-statistic for this test is calculated as follows:
t = (sample mean - null mean) / (standard deviation / sqrt(sample size))
Plugging in the values from the problem, we have:
t = ($1,950 - $1,800) / ($500 / sqrt(40)) = 2.5.
We can then use a t-table or a computer to find the critical value of t for a one-tailed t-test with 39 degrees of freedom and a significance level of 0.05. The critical value is 1.68.
Since the calculated t-value of 2.5 is greater than the critical value, we can reject the null hypothesis and conclude that the true mean claim amount is significantly greater than the original estimate of $1,800.
Therefore, the insurance company should be concerned that they could potentially lose money.

Mean = 95.125
Variance = 198.90625
Standard deviation = 14.06,
Confidence interval = 95.125 +/- 3.45
To find the 95% confidence interval of the mean score for all bowlers in this league, we need to first calculate the sample mean and sample standard deviation of the given data set.
The sample mean is calculated as follows:
mean = (96 + 103 + 94 + 105 + 91 + 101 + 99 + 89 + 94 + 91 + 82 + 94 + 97 + 99 + 89 + 107 + 97 + 100 + 96 + 92 + 96 + 95 + 99 + 90 + 84 + 97 + 99 + 87 + 102 + 92 + 91 + 90 + 88 + 103 + 94 + 90 + 98 + 91 + 87) / 40mean = 95.125
The sample standard deviation is calculated as follows:
First, we need to calculate the variance of the data set, which is done by taking the sum of the squared differences between each score and the mean, and dividing by the sample size minus 1:
variance = ((96 - 95.125)^2 + (103 - 95.125)^2 + (94 - 95.125)^2 + (105 - 95.125)^2 + (91 - 95.125)^2 + (101 - 95.125)^2 + (99 - 95.125)^2 + (89 - 95.125)^2 + (94 - 95.125)^2 + (91 - 95.125)^2 + (82 - 95.125)^2 + (94 - 95.125)^2 + (97 - 95.125)^2 + (99 - 95.125)^2 + (89 - 95.125)^2 + (107 - 95.125)^2 + (97 - 95.125)^2 + (100 - 95.125)^2 + (96 - 95.125)^2 + (92 - 95.125)^2 + (96 - 95.125)^2 + (95 - 95.125)^2 + (99 - 95.125)^2 + (90 - 95.125)^2 + (84 - 95.125)^2 + (97 - 95.125)^2 + (99 - 95.125)^2 + (87 - 95.125)^2 + (102 - 95.125)^2 + (92 - 95.125)^2 + (91 - 95.125)^2 + (90 - 95.125)^2 + (88 - 95.125)^2 + (103 - 95.125)^2 + (94 - 95.125)^2 + (90 - 95.125)^2 + (98 - 95.125)^2 + (91 - 95.125)^2 + (87 - 95.125)^2) / (40 - 1)variance = 198.90625
The sample standard deviation is then the square root of the variance:
standard deviation = sqrt(198.90625)
standard deviation = 14.06
Now that we have the sample mean and sample standard deviation, we can use these values to calculate the 95% confidence interval of the mean score for all bowlers in this league.
We can use the following formula to calculate the confidence interval:
confidence interval = mean +/- (1.96 * (standard deviation / sqrt(sample size)))
Substituting in the values we calculated above, we get:
confidence interval = 95.125 +/- (1.96 * (14.06 / sqrt(40)))
Hence , confidence interval = 95.125 +/- 3.45

x = 27 / 0.90 = 30 oz
Think of two numbers that multiply to -24, but add to -14.
Answer:
x = -7 + √(73)
y = -7 - √(73)
Step-by-step explanation:
Product p = x × y = -24
Somme s = x + y = -14
Then
x and y are solutions to the equation:
z² - sz + p = 0
Then
x and y are solutions to the equation:
z² + 14z - 24 = 0
Using the quadratic formula:
x = ( -14 + √[(14² - 4×(1)×(-24)] ) / ( 2×(1) ) = -7 + √(73)
and
y = ( -14 - √[(14² - 4×(1)×(-24)] ) / ( 2×(1) ) = -7 - √(73)
The same series of books you've been wanting cost 44$ at
Barnes and no ble and are on sale for 35gat target. If you have a 25.1.
off Coupon for Barnes and noble and a 51. Red card discount at target,
find what the price before tax would be at each of the two
retailers.
The price before tax of the books at Barnes and Noble would be 44$ - 25.1$ = 18.9$ if you use your coupon.
The price before tax of the books at Target would be 35$ - 51.1$ = -16.1$ if you use your Red card discount. However, the final price of the books cannot be negative, so the price before tax of the books at Target would be 35$ if you use your Red card discount.
A one-factor ANOVA is used to evaluate the mean differences among four treatment conditions with a sample of n = 12 participants in each group. For this study, what is dfwithin treatments?
In this case, with four treatment groups and n = 12 participants in each group, dfwithin treatments would be equal to 3, because there are 4 - 1 = 3 treatment groups.
In a one-factor ANOVA, dfwithin treatments refers to the degrees of freedom within the treatment groups, which is a measure of the amount of variability that is present within each group.
The degrees of freedom within the treatment groups is used to calculate the mean square within treatments (MSwithin), which is a measure of the variability within each group. MSwithin is calculated by dividing the sum of the squared differences between each participant's score and the group mean by dfwithin. This value is then used to determine the statistical significance of the treatment effects, by comparing it to the mean square between treatments (MSbetween), which is a measure of the variability between the treatment groups.
In a one-factor ANOVA, the total degrees of freedom is equal to the number of participants in all of the groups combined (4 groups * 12 participants per group = 48) minus the number of groups (48 - 4 = 44). The degrees of freedom between treatments is equal to the number of groups minus 1 (4 - 1 = 3), and the degrees of freedom within treatments is equal to the total degrees of freedom minus the degrees of freedom between treatments (44 - 3 = 41).

The graphs below have the same shape. f(x)=x². What is the equation of the graph of g(x) ?
A. g(x)=(x-2)²
B. g(x)=(x+2)²
C. g(x)=x²+2
D. g(x)=x²-2
The equation of the graph of the function g(x) is A. g(x) = (x - 2)²
How to determine the equation of the graph of the function g(x)?From the question, we have the following parameters that can be used in our computation:
f(x) = x²
Also, we have the given graph
From the graph, we can see that the graph f(x) is shifted right y 2 units
This means that
g(x) = f(x - 2)
So, we have
g(x) = (x - 2)²
Hence, the equation is (a) g(x) = (x - 2)²

Alfonso is making chili for a get-together.
His recipe calls for 1 1/2 cups of diced tomatoes for every 3 cups of chili.
He wants to make 13 cups of chili.
How many cups of diced tomatoes should he put in the chili?
Answer is a mixed number
The cups of diced tomatoes the Alfonso should put in the chili is 6 1/2 cups.
How to calculate the number of cups?A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.
Let the number of cups be x.
Based on the information, this will be illustrated as:
1.5 / x = 3/13
Cross multiply
3x = 13 × 1.5
3x = 19.5
Divide
x = 19.5 / 3
x = 6 1/2
The cups needed is 6 1/2 cups.
