So,we know that it take 0.8 of a minute or 48 seconds to read each page of a health book, so it will take 300 seconds to read 6.25 pages. As a result, it will take 10.5 minutes to finish reading 6.25 pages and also taking a test. Hope it help!

Answer:

39.375 minutes

Step-by-step explanation:

Since, each test on a page takes 5.5 minutes while each page take 0.8 minutes to read. So, for 6.25 pages. So, to give the test of 6.25 pages, time will be:

(6.25).(5.5)

34.375 minutes.

Now, to read these 6.25 pages, time will be:

(6.25).(0.8)

5 minutes

So, the total time taken is

34.375 + 5

39.375 minutes

If the diameter of a circle is 80 ft., find the area A 5,024 ft2 B 20,096 ft2 C 251.2 ft2 D 125.6 ft2

A. 5,024

If the diameter is 80 feet, the radius is 40 ft.

Area of a circle = (pi)(r^2)
A = 3.14 x 40^2
A = 5,042

A sprinkler system is being installed in a newly renovated building on campus. The average activation time is supposed to be at
melomori [17]

Answer:

A) t = 1.73

B) p-value =  0.0558

C) Data is not statistically significant because the p-value of 0.0558 is more than the significance value of 0.05

D) The decision means that the design specifications are not met.

E) Type II error

Step-by-step explanation:

The hypotheses are:

H₀: μ = 20

H₁: μ > 20

A) Formula for the test statistic is;

t = (x' - μ)/(s/√n)

Now, we are given;

x' = 21.5

μ = 20

s = 3

n = 12

Thus;

t = (21.5 - 20)/(3/√12)

t = 1.73

B) we have our t-value as 1.73

Now, Degree of freedom(DF) = n - 1

So,DF = 12 - 1 = 11

Using significance level of α = 0.05, t-value = 1.73 and DF = 11, one tailed hypothesis, from online P-value calculator attached, we have;

p-value =  0.0558

C) Data is not statistically significant because the p-value of 0.0558 is more than the significance value of 0.05

D) We will not reject the null hypothesis. The decision means that the design specifications are not met.

E) If the true average activation time of the sprinkler system is, in fact, equal to 20 seconds, then the null hypothesis is false.

Since we did not reject the null hypothesis even though it is false, the error that was committed was therefore a type II error.

pat needs 14 sticks of pepperoni to make 28 pizzas.How many sticks of pepperoni are needed to make 36 pizzas
Marizza181 [45]

Answer:

18 sticks of pepperoni

Step-by-step explanation:

In order to solve this problem, we have to find out how many pepperoni sticks are needed for just 1 pizza. If it takes 14 sticks to make 28 pizzas, that means it takes only half a stick to make a single pizza.

Now that we have this information, we can multiply 1/2 by 36 to find out how many sticks of pepperoni are needed to make 36 pizzas.

\frac{1}{2} * 36\\\\\frac{1}{2} * \frac{36}{1} \\ =\\\frac{36}{2} \\ =\\\frac{18}{1}

Therefore, it takes 18 sticks of pepperoni to make 36 pizzas. I hope this helps! Have a lovely day!! :)
