Answer:
Guys the answer is E. I just took the test.
Step-by-step explanation:
Short answer: Look at the inequalities and plug in either 10 or 8 for m and then you're all set :)
Long Answer:So what you should do first is calculate how long she hikes for and how many mph. It says that she likes the hike for more than 4 hours but less than six. She also hikes at least 2 mph. So if you were ever in first grade you would know that she hikes for at least 5 hours. Now 5 x 2 is 10. Now you can either plug 8.0 into the inequalities or 10 but either way its going to be more than whatever number is first in the inequality but less than 12.

A scientist measures the heights of sunflower plants. The histogram shows the results. Which statement is correct?
Where's the histogram?
Answer:
C. The data are skewed to the left, so the median height is greater than the mean height.
Step-by-step explanation:
If this is this is what your questions look like, then the answer is C because the mean is typically less than the median when the data is skewed left.

The function h(t)=-16t^2+75t+80 models the height in feet, h, of a ball as it is thrown into the
air at time, t, in seconds. At which of the following times will the ball be 124 feet above the
ground?
Answer:
[tex]t = 4\\[/tex]
or
[tex]t=0.6875[/tex]
Step-by-step explanation:
[tex]124 = -16t^2+75t+80\\-16t^2+75t-44=0[/tex]
Solving for t using the quadratic formula we get:
[tex]t = 4\\[/tex]
or
[tex]t=0.6875[/tex]
The times taken by the ball to be 24 feet above the ground is t = 4 and t = 0.68 seconds.
What is meaning of the term function?an expression, rule, or law defining a connection between one variable (a independent variable) and the other (the dependent variable). Functions are common in mathematics and are required for the formulation of actual relationships with in sciences.The function given for the height of the ball thrown is;
h(t) = -16t^2+75t+80
In which, h is the height in feet,
t, is the time till ball is in air( in seconds. )
When height h = 124 feet.
Time t = ?
Put h = 124 in the given equation.
124 = -16t^2+75t+80
On solving.
-16t^2+75t-44 = 0.
16t^2 - 75t + 44 = 0.
Solve the quadratic equation by the quadratic formula,
t = 4 and t = 0.68 seconds.
Thus, the times taken by the ball to be 24 feet above the ground is t = 4 and t = 0.68 seconds.

Can someone show me how you get it and the answer
Answer: b=8 m=2
Step-by-step explanation: when x is 0 y=8 so that gives you the y-intercept. When you subtract 8-6 its 2 which is over 2 which is 2
Answer: y = -2x + 4
Step-by-step explanation:
First, you can find b (the y-intercept) from the coodinates. Where y=0, x=4. This is your y intercept (b).
To find the slope (m), take two points from the graph:
Let's use (2,4) and (3,2). Next, find the difference in the x and y values.
Difference in Y = 4-2 = 2
Difference in X = 2 - 3 = -1
Now we can find the slope by dividing the difference in y values by the difference in x values:
2/-1 = -2 (m = -2)
Now plug the values for b and m into your equation.
y = -2x + 4

Please answer thisssssssssssssssss
Answer:
56
Step-by-step explanation:
by the formula at the bottom, it would be 1/2h(b1 + b2)
so h = height and the height is 7 feet. 1/2 of 7 feet is 3.5
b1 would be 12 feet, and b2 would be 4 feet. so first let’s do the (. )
12 + 4 = 16
now the problem is 3.5(16)
3.5 x 16 = 56
now i just went off the formula, but i think that’s right. good luck!
Answer:

A 98% confidence interval for a proportion is found to be (0.47, 0.53). What is
the sample proportion?
A. 0.53
B. 0.51
C. 0.49
D. 0.50
Answer:
0.50
Step-by-step explanation:
The sample proportion to be found for 98% confidence interval is
D. 0.50.
What is a confidence interval?The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval.
Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test.
In statistics, confidence is another word for probability.
Given, Sample = (0.47, 0.53).
Confidence interval = 98%.
Therefore, The sample proportion is,
= (0.47 + 0.53)/2.
= 1/2.
= 0.5.
So, The sample proportion is 0.50.

Type the correct answer in the box. Use numerals instead of words.
A charter fishing boat sold a total of 50 tickets for its two trips yesterday,
There were 19 adults and 7 children on the morning trip. There were 24 adults on the evening trip.
The probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip is
%.
The probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip is 0.62 or 62%.
To calculate the probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip, we will use the formula: $P(\text{Child or Evening Trip}) = P(\text{Child}) + P(\text{Evening Trip}) - P(\text{Child and Evening Trip})$.We are given that there were 7 children on the morning trip and 24 adults on the evening trip.
Therefore, the number of children who were on the evening trip is 0. Hence, $P(\text{Evening Trip}) = 24/50 = 0.48$.
Similarly, the number of children who were not on the evening trip is 7, while the number of adults who were not on the evening trip is $50 - (7 + 24) = 19$. Hence, $P(\text{Child}) = 7/50 = 0.14$.
Since no child was on the evening trip, $P(\text{Child and Evening Trip}) = 0$.
Substituting these values in the formula above, we get: $P(\text{Child or Evening Trip}) = 0.14 + 0.48 - 0 = 0.62$
Therefore, the probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip is 0.62 or 62%.
