The amount of people who do the hurdles:
\frac{3}{8}  \times 40 = 15
From this 15 people, the following amount does long jump:
\frac{4}{5}  \times 15 = 12
So the answer is 12 people.

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4 °F. The submarine div
aleksley [76]

Answer:

-502.5 - 115 = - 617.5

63 1/4 - 2 1/5 =  

63 - 2 = 61

1/4 - 1/5 = 5/20 - 4/20 = 1/20

so 63 1/4 - 2 1/5 = 61 1/20

after the sub dove, elevation level is - 617.5 and temp is 61 1/20 F

The pH of randomly selected swimming pools follows a normal distribution with mean 7.4 and standard deviation 0.22. A pool shoul
skad [1K]

Answer:

78.383%

Step-by-step explanation:

The pH of randomly selected swimming pools follows a normal distribution with mean 7.4 and standard deviation 0.22. A pool should have a pH between 7.2 and 7.8 so that chlorine treatment is effective.

Using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

For x = 7.2

z = 7.2 - 7.4/0.22

z = -0.90909

Probability value from Z-Table:

P(x = 7.2) = 0.18165

For x = 7.8

z = 7.8 - 7.4/0.22

z = 1.81818

Probability alue from Z-Table:

P(x = 7.8) = 0.96548

The probability of pools having an acceptable pH level(7.2 and 7.8)

= P(x = 7.8) - P(x = 7.2)

= 0.96548 - 0.18165

= 0.78383

Converting to percentage

0.78383 × 100

= 78.383%

The percentage of pools having an acceptable pH level is 78.383%

Simplify the expression (picture down below)
pav-90 [236]

Answer:

6.75

Step-by-step explanation:

The term 6.75 is within absolute value bars. These bars force any term inside of them to be positive. Since 6.75 is already positive, the bars have no effect.

The term 6.75 is already simplified.

A children clothing manufacturer has 500 yards of material to make shirts and skirts. A shirt requires 0.5 yards of fabric, and
konstantin123 [22]

Answer:

C.\ \ \ \\\\\x\geq 0\ \ \ ,y\geq 0\\\\0.5x+y\leq 500\\\\x+1.5y\leq 800

Step-by-step explanation:

We first denote the inequalities of the number of shirts and skirts.

#Since you cannot make a negative number of shirts or skirts, the inequalities will be written as:

Shirts=> x\geq 0\\\\skirts=>y\geq 0

#We then represent the inequality of material.

-The material size is a production constraint as only 500 yards of material is available for use.

-The inequality is therefore  written as:

x \ takes \ 0.5\  yards\\y\ takes \ 1 \ yard\\\\\therefore 0.5x+y\leq 500

#We then represent the inequality of time.

-The material size is a production constraint as only 800 hours available for use.

-The inequality is therefore  written as:

x \ takes\  1 \ hr\\y \ takes\  1.5 \ hr\\\\\therefore x+1.5y\leq 800

We combine the three inequalities to represent the constraints

x\geq 0\ \ \ ,y\geq 0\\\\0.5x+y\leq 500\\\\x+1.5y\leq 800
