Mitch throws a ball over A 20 foot fence to a baseball field. The height, H, of the ball at the time T seconds after it was the round can be modeled by the equation H(t)=16^2 + 30t+6


which statement is true?

Answer:

40 days saw either rain or high winds

Step-by-step explanation:

We solve this question using Venn sets.

I am going to say that:

Set A: Rain

Set B: High winds.

18 days saw rain

This means that [tex]A = 18[/tex]

29 days saw high winds

This means that [tex]B = 29[/tex]

7 days saw both rain and high winds.

This means that [tex]A \cap B = 7[/tex]

How many days saw either rain or high winds?

This is

[tex]A \cup B = A + B - A \cap B[/tex]

Sp

[tex]A \cup B = 18 + 29 - 7 = 40[/tex]

40 days saw either rain or high winds

Answer:

The 95% confidence interval is "87.94, 91.86".

Step-by-step explanation:

The given values are:

Sample batches,

n = 25

Sample mean concentration,

[tex]\bar{x}[/tex] = 89.9 mg

Amount of chemical,

σ = 5

α = 0.05

The critical value from Z table will be:

=  [tex]Z(\frac{\alpha}{2} )[/tex]

=  [tex]Z(\frac{0.05}{2} )[/tex]

=  [tex]1.96[/tex]

Now,

The confidence interval will be:

=  [tex]\bar{x} \pm Z(\frac{\alpha}{2} )\times \frac{\sigma}{\sqrt{n} }[/tex]

On substituting the values, we get

=  [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{\sqrt{25}}[/tex]

=  [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{5}[/tex]

=  [tex]89.9 \pm1.96\times 1[/tex]

Lower limit will be:

=  [tex]89.9 -1.96\times 1[/tex]

=  [tex]87.94[/tex]

Upper limit will be:

=  [tex]89.9 +1.96\times 1[/tex]

=  [tex]91.86[/tex]

Answer:

17500

Step-by-step explanation:

17499 rounds down

17500 rounds up

The number of people is an illustration of approximation and estimation

The minimum possible number of people at the festival is 17500

The approximated number of people is:

People  = 18000

Because 18000 represents people, it means that the population is a whole number

The smallest whole number that can be approximated to 18000 is 17500

i.e.

People = 17500

Hence, the minimum possible number of people at the festival is 17500

Answer:

[tex] \therefore x =2[/tex]

Step-by-step explanation:

[tex] \triangle TPR \sim \triangle SQR... (given) [/tex]

[tex] \therefore \frac{TP}{SQ} = \frac{PR}{QR}[/tex]

[tex] \therefore \frac{TP}{SQ} = \frac{PQ+QR}{QR}[/tex]

[tex] \therefore \frac{3}{x} = \frac{1\frac{1}{3} +2 \frac{2}{3}}{2 \frac{2}{3}}[/tex]

[tex] \therefore \frac{3}{x} = \frac{\frac{4}{3} + \frac{8}{3}}{\frac{8}{3}}[/tex]

[tex] \therefore \frac{3}{x} = \frac{\frac{12}{3}}{\frac{8}{3}}[/tex]

[tex] \therefore \frac{3}{x} = \frac{12}{8}[/tex]

[tex] \therefore x = \frac{8\times 3}{12}[/tex]

[tex] \therefore x = \frac{24}{12}[/tex]

Answer:

Four (4); 45; at least; 181.

Step-by-step explanation:

Ali has four friends that owe him x dollars each. His parents owe him $45 for doing chores last week. He recalls that people owed him at least $181.

To find how much money each of Ali's friends owe him;

Given the algebraic expression;

4x + 45 ≤ 181

4x ≤ 181 - 45

4x ≤ 36

Dividing both sides by 9, we have;

x ≤ 9

Therefore, Ali's friends owe him at least $9 each.

Answer:

Four (4); 45; at least; 181.

A scalene right has no equal side lengths, has a right side(90) and will have two angles less than 90 because all three triangle sides need to equal to be 180. So scalene right is your answer. Hope that helped!

Answer:

Domain: [tex]-6 \leq x \leq 3[/tex]

Range: [tex]-3 \leq x \leq 6[/tex]

Step-by-step explanation:

The domain is the set of real values which can be inputted into a function and produce a real output. In this case, the domain is the following: [tex]-6 \leq x \leq 3[/tex], because this is the set of real values for which the function will produce a real output.

The range is the set of real values which a function outputs when a value from the domain is entered into the function. This is the set of y-values that one can see on the graph, the possible y-values are in between (-3) and (6).

Answer:

(-2, -7), (0, -3), (2, 1)

Step-by-step explanation:

Equation is given as y = 2x - 3.

To complete the table, plug in each value of x into y = 2x - 3 to get their corresponding y-value.

✔️When x = -2:

y = 2(-2) - 3

y = -4 - 3

y = -7

✔️When x = 0:

y = 2(0) - 3

y = -3

✔️When x = 2:

y = 2(2) - 3

y = 4 - 3

y = 1

Answer:

A is correct.

Step-by-step explanation:

Here, the x would represent the gallons per minute. The minutes are unknown, so it's just a variable. It can't be B either, because the addition sign would mean that the pool is being filled instead of drained.

Answer:

[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]

Step-by-step explanation:

Given [Missing]

[tex]A = (-3,4)[/tex]

[tex]B = (1,3)[/tex]

[tex]C =(3,6)[/tex]

[tex]D =(1,6)[/tex]

The first transformation: reflection across the y-axis.

The rule is: [tex](x,y)==>(-x,y)[/tex]

So:

[tex]A = (-3,4)[/tex] ==>[tex]A' = (3,4)[/tex]

[tex]B = (1,3)[/tex] ==> [tex]B' = (-1,3)[/tex]

[tex]C =(3,6)[/tex] ==> [tex]C' = (-3.6)[/tex]

[tex]D =(1,6)[/tex] ==> [tex]D' = (-1,6)[/tex]

Translation 2 units down

The rule is: [tex](x,y)==>(x,y-2)[/tex]

So:

[tex]A' = (3,4)[/tex] ==> [tex]A" =(3,4-2) =(3,2)[/tex]

[tex]B' = (-1,3)[/tex] ==> [tex]B" = (-1,3-2) = (-1,1)[/tex]

[tex]C' = (-3.6)[/tex] ==> [tex]C" = (-3,6-2) = (-3,4)[/tex]

[tex]D' = (-1,6)[/tex] ==> [tex]D" =(-1,6-2) = (-1,4)[/tex]

Hence:

[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]
