Answer:

Team A: 25 players

Team B: 24 players

Step-by-step explanation:

Team A:

to find the total # of players of the team we need to set up a fraction. 5 out out of an unknown number of players is equal to 1/5, so we set it up as:

$\frac{5}{x} = \frac{1}{5}$

then we cross multiply to get

x*1 = 5*5

x=25 players

Team B

similarly to Team A

$\frac{3}{x} = \frac{1}{8}$

cross multiply to get

x*1=3*8

x= 24 players

Molodets [167]

Answer:

Hip breadths less than or equal to 16.1 in. includes 90% of the males.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 14.5

Standard Deviation, σ = 1.2

We are given that the distribution of hip breadths is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.10.

P(X > x)

$P( X > x) = P( z > \displaystyle\frac{x - 14.5}{1.2})=0.10$

$= 1 -P( z \leq \displaystyle\frac{x - 14.5}{1.2})=0.10$

$=P( z \leq \displaystyle\frac{x - 14.5}{1.2})=0.90$

Calculation the value from standard normal z table, we have,

$P(z < 1.282) = 0.90$

$\displaystyle\frac{x - 14.5}{1.2} = 1.282\\x = 16.0384 \approx 16.1$

Hence, hip breadth of 16.1 in. separates the smallest 90% from the largest 10%.

That is hip breaths greater than 16.1 in. lies in the larger 10%.

Jason has $2.25 worth of dimes and quarters he has twice as many dimes as quarters determine the number of dimes and the number

iris [78.8K]

Answer: jason has 10 dimes and 5 quarters.

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a quarter is 25 cents. Converting to dollars, it becomes

25/100 = $0.25

Let x represent the number of dimes that he has.

Let y represent the number of quarters that he has.

He has twice as many dimes as quarters. This means that

x = 2y

Jason has $2.25 worth of dimes and quarters. This means that

0.1x + 0.25y = 2.25 - - - - - - - - - - - 1

Substituting x = 2y into equation 1, it becomes

0.1 × 2y + 0.25y = 2.25

0.2y + 0.25y = 2.25

0.45y = 2.25

y = 2.25/0.45

y = 5

x = 2y = 2 × 5

x = 10
