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.

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.

Answer:

Step-by-step explanation:

The difference in balances is:

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:

56

Step-by-step explanation:

Area of a Trapezium = 1/2 × sum of parallel sides× height

= 1/2× (12+4)×7

=1/2 × 16×7

= 8×7

= 56

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.

Answer:

0.50

Step-by-step explanation:

The sample proportion to be found for 98% confidence interval is

D. 0.50.

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.

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

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%.
