Answer:

The required P value is 0.0901.

The critical value for the test statistic is 1.645.

Step-by-step explanation:

Consider the provided information.

The test statistic of z=1.34 is obtained when testing the claim that p> 0.1

It is given given that z=1.34 as the claim has greater than inequality so it is a right tailed test.

Part (A) P-value

P\ value=1-P(Z\leq z)\\P\ value=1-P(Z\leq 1.34)

From the Standard normal distribution table P(Z\leq 1.34) =0.9099.

Therefore,

P\ value=1-0.9099=0.0901

Hence, the required P value is 0.0901.

Part (B) The critical value(s) is/are z=

It is given that the significance level is α=0.05

Using standard z value table we get the critical value for the test statistic is 1.645.

Hence, the critical value for the test statistic is 1.645.

17 = 5-x what's the answer​
TEA [102]

Answer:

X = - 12.

Step-by-step explanation:

17 = 5 - x

17 = 5 + - x

17 = - x + 5

Then, flip the equation.

-x + 5  = 17

Then subtract 5 from both of the sides.

-x + 5 - 5 = 17 - 5

-x = 12

Then divide

-x/ -1 = 12/1

x = - 12.

Hope this helps!

After the semester is over, you discover that the math department has changed textbooks (again) so the bookstore won't buy back
zaharov [31]

Answer:

0.78 s

Step-by-step explanation:

Since the position of the pool is at 60 feet below, s(t) = -60 for both me and Anna. So, both expressions for the motion of the book are equated to -60 and then solved to find the time they reach the water.

So, For me s(t)= −16t² + 60

-60 = −16t² + 60

collecting like terms, we have

-60 - 60 = −16t²

- 120 = −16t²

dividing both sides by - 16, we have

t² = -120/-16

t² = 7.5

t = √7.5

t = 2.74 s

For Anna, s(t)= −16t² - 30t + 60

-60 = −16t² - 30t + 60

adding 60 to both sides, we have

-60 + 60 = −16t² - 30t + 60 + 60

−16t² - 30t + 120 = 0

dividing through by -2, we have

8t² + 15t - 60 = 0

Using the quadratic formula to find t

t = \frac{-15 +/- \sqrt{15^{2} - 4 X 8 X -60} }{2 X 8} \\t = \frac{-15 +/- \sqrt{225 + 1920} }{16} \\t = \frac{-15 +/- \sqrt{2145} }{16} \\t = \frac{-15 +/- 46.31}{16} \\t = \frac{-15 - 46.31}{16}  or t = \frac{-15 + 46.31}{16} \\t = \frac{-61.31}{16}  or t = \frac{31.31}{16} \\t = -3.83 s or 1.96 s

Since t' cannot be negative, t' = 1.96 s.

It takes Anna's book 1.96 s to reach the water, while it takes 2.74 s for my book to reach the water.

So, the time it takes Anna's book to beat mine is the difference between the time of reaching the water of each book. So Δt = t - t' = 2.74 s - 1.96 s = 0.78 s

Enrique can spend at most $2240 to renovate his home. One roll of wallpaper costs $32, and one can of paint costs $28. He needs
4vir4ik [10]

The possible solution is having 30 rolls of wallpaper and 20 can of paints or 52 rolls of wallpaper with 20 can of paint.

<h3>Inequality</h3>

Inequality is the non equal comparison of two or more numbers and variables.

Let x represent the number of wallpapers and y represent the number of cans.

He needs at least 30 rolls of wallpaper and at least 20 cans of paint. Hence:

x ≥ 30   (1);

y ≥ 20    (2)

Also:

32x + 28y ≤ 2240    (3)

Plotting the 3 equations using geogebra online graphing tool, the possible solution is:

(30, 20), (52, 20)

The possible solution is having 30 rolls of wallpaper and 20 can of paints or 52 rolls of wallpaper with 20 can of paint.
