Find the slope of the line that passes through each pair of points
Answer:
Slope of 2
Step-by-step explanation:
First thing is to look at the change in x and y from the points. You can do this by subtracting the x valie from the other value and the same for the y values. So you would do 2-0=2.
So we know the change in x between the points, so now we find the change in y. 5-1=4.
Now that we know the change in x and y, we use the expression below to solve for the slope.
[tex] \frac{rise}{run} \: or \: \frac{y}{x} [/tex]
We can insert what we found and then solve for the equation
[tex] \frac{4}{2} [/tex]
So we solve for that, which is 2. Now we know the slope is 2.
Answer:
given us,
(x1y1)= (2,5)
(x2y2)= (0,1)
here,
(y-y1)= (y2-y1)/ (x2-x1)× (x-x1)
or, (y-5)=(1-5)/(0-2)× (x-2)
or, y-5= -4/-2 ×(x-2)
or,y-5= 2(x-2)
or, y-5/ x-2= 2
or,y-5= 2x-4
or, 2x-y= -4+5
:. 2x-y= 1
Step-by-step explanation:
2x-y= 1
If a child weighs 83 pounds, how many ounces does she weigh? 664 oz. 664 oz. 830 oz. 830 oz. 966 oz. 966 oz. 1328 oz.
Answer:
The answer is 1,328
Step-by-step explanation:
The number of ounces that she weighs will be 1328 ounces. Then the correct option is D.
What is conversion?Conversion means converting the same thing into different units.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
If a child weighs 83 pounds. We know that in one pound, there are 16 ounces.
Then the number of ounces that she weighs will be
⇒ 83 x 16
⇒ 1328 ounces
Then the number of ounces that she weighs will be 1328 ounces. Then the correct option is D.

Step-by-step explanation:
working alone, kali can pick forty bushels of apples in 15 hours,l. One day her friend Natalie helped her and it only took 6 hours. How long would it take Natalie to do it alone.
(please help I'm struggling)
Answer:
The time it will take Natalie to pick the forty bushels alone is 10 hours
Step-by-step explanation:
The time it takes Kali to pick forty bushels of apples alone = 15 hours
The time it takes Kali and Natalie to pick forty bushels = 6 hours
The rate at which Kali picks bushels = 40/15 bushels per hour = 8/3 bushels per hour
Let x represents the rate at which Natalie picks bushels, we have;
8/3 × 6 + x × 6 = 40
x × 6 = 40 - 8/3 × 6 = 24
x = 24/6 = 4
Therefore;
The rate at which Natalie picks the bushels of apples = 4 bushels/hour
The time it will take Natalie to pick the forty bushels alone = (40 bushels)/(4 bushels/hour) = 10 hours.

solve the following equation x^2 + 27=-9
Step-by-step explanation:
x²=-9-27
x²=-36
there's no x
Answer:
x = ± 6i
Step-by-step explanation:
Given
x² + 27 = - 9 ( subtract 27 from both sides )
x² = - 36 ( negative value indicates the solutions are complex )
Take the square root of both sides
x = ± [tex]\sqrt{-36}[/tex] = ± 6i

What single percentage change is equivalent to a 8% decrease followed by a 15% decrease
Answer:
Calculate Percentage Decrease:
First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100.
Step-by-step explanation:
The percentage change is equivalent to a 8% decrease followed by a 15% decrease is 78.2%.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
We have to find percentage change is equivalent to a 8% decrease followed by a 15% decrease.
So, (1- 8%)(1- 15%)
= (1- 8/100)(1-15/100)
= (1-0.8)(1-0.15)
= 0.92 x 0.85
= 0.782
Now, converting to percentage
= 0.782 x 100/100
= 78.2 /100
= 78.2%

A binomial event has n = 35 trials. The probability of success for each trial is 0.45. Let x be the number of successes of the event during the 35 trials. What are μx and σx? (4 points) a)15.75 and 3.1996 b)15.75 and 2.9432 c)19.25 and 2.9432 d)19.25 and 3.1996 e)30 and 2.9432
Answer:
b)15.75 and 2.9432
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
The mean of a binomial distribution is:
[tex]\mu[/tex] = np
And the standard deviation is
[tex]\sigma[/tex] = √(npq)
where,
n = 35,
p = 0.45,
and q = 1 - 045 = 0.55
Now mean is
= 35 × 0.45
= 15.75
And, the standard deviation is
= √(35 × 0.45 × 0.55)
= 2.9432
Hence, the correct option is B.
Ella made a checker board. Each individual square has a side with a length of x + 3. Find the area of the ENTIRE board in terms of x if each side of the board is made up of 6 congruent squares.
Answer:
Total area of board = 36x² + 324 + 216x
Step-by-step explanation:
Given:
Side of square = x + 3
Total number of square = 6 x 6 = 36
Area of each square = Side x Side
Area of each square = (x + 3)²
Area of each square = x² + 9 + 6x
Total area of board = 36[Area of each square]
Total area of board = 36[x² + 9 + 6x]
Total area of board = 36x² + 324 + 216x

the lenth of a quarter is 0.955 inch round the length of a quarter to the nearest tenth of an inch.
Answer: 1 inch
Step-by-step explanation: when you round to the tenth place, you look at the number to the right of the decimal. Because it is .95, you round up. If it was .94 or under, you would round down. .95 rounded up would make 10 in the tenths place, so we add our decimal to get 1.0, or 1 inch
A well respected wild life researcher recently conducted a
study of wild Jackalopes. He trapped and weighed 60 adult
wild Jackalopes in an attempt to gauge their health. As a
population, if a species loses weight it could be a signal
that the health of the population is in danger. Research conducted 10 years prior found that the population mean was 69.9 pounds. Test the claim that population mean of wild Jackalopes is equal to 69.9 lbs. Use a significance level of .01.
Claim: ______________
Null Hypothesis: ________
Alternative Hypothesis: ___________________________
Test Statistic: (state the statistic and find it’s value):
Find the pvalue for the given test statistic:
At the 0.01 significance level would you reject the null or fail to reject the null? Justify your answer.
What final conclusion could you draw from your research?
Answer:
Claim : men weigh of wild jackalopes is 69.9
The null hypothesis : H0 : μ = 69.9
Alternative hypothesis : H1 : μ ≠ 69.9
Test statistic = −2.447085
P value = 0.0174
Conclusion :
Fail to Reject the Null hypothesis
Step-by-step explanation:
From the question given :
The claim is that : mean weight of wild jackalopes is still the same as 10 years with a mean weight of 69.9 lbs.
The null hypothesis : H0 : μ = 69.9
Alternative hypothesis : H1 : μ ≠ 69.9
Using calculator :
Sample mean (x) = 66
Sample standard deviation (s) = 12.345
The test statistic t :
(x - μ) / (s/√n)
n = sample size = 60
(66 - 69.9) / (12.345 / √60)
t = −2.447085
P value at α 0.01, df = 59 is 0.0174
Since the p value is > 0.01, the result is not significant at 0.01. Therefore, we fail to reject the Null

An architect built a scale model of a shopping mall. On the model, a circular fountain is 21 inches tall and 17.5 inches in diameter. If the actual fountain is to be 6 feet tall, what will its diameter be?
Answer:
The diameter is 5ft
Step-by-step explanation:
Given
[tex]Height : Diameter = 21\ in: 17.5\ in[/tex]
Required
Determine the diameter when the height is 6ft
Recall that the scale is a ratio of height to diameter;
So 6ft height can be represented on the following scale model;
[tex]Height : Diameter = 6ft : x[/tex]
Convert to fraction
[tex]\frac{Height}{Diameter} = \frac{6}{x}[/tex] ---- (1)
Recall that:
[tex]Height : Diameter = 21\ in: 17.5\ in[/tex]
Convert to fraction
[tex]\frac{Height}{Diameter} = \frac{21 }{17.5}[/tex] ---- (2)
Equate (1) & (2)
[tex]\frac{6}{x}= \frac{21 }{17.5}[/tex]
Cross Multiply
[tex]21 * x = 6 * 17.5[/tex]
[tex]21x = 105[/tex]
[tex]x = 105/21[/tex]
[tex]x = 5[/tex]
Hence, the diameter is 5ft
