Answer:

The correct answer is:

C. Trisha is shorter than 75% of girls aged 16 to 18.

Step-by-step explanation:

When a dataset is divided into four equal parts, the first part is called the lower quartile. The data is usually sorted in ascending order before finding quartiles.

The lower quartile contains 25% of the whole data. The values in lower quartile are are less than 75% of the values.

If Trisha's height is in lower quartile that means her height is less than the girls in middle and higher quartile.

Hence,

The correct answer is:

C. Trisha is shorter than 75% of girls aged 16 to 18.

Hi, thank you for posting your question here at Brainly.

This problem could be solved using the Law of Cosines, since we are given with the three sides. The equation goes,

b^2 = a^2 + c^2 - 2accosB. Substituting,

24^2 = 7^2 + 25^2 - 2(7)(25)cosB

Then B = 73.7 degrees. Therefore sinB or sin(73.7) = 0.96.

Lapatulllka [165]

The right answer is Option A.

Step-by-step explanation:

Given,

Heart rate goal = I

Heart rate reserve = H

70% of H = \frac{70}{100}H = 0.7H

Resting heart rate = R

According to given statement,

70% of heart rate reserved is added to resting heart rate to calculate heart rate goal, therefore,

I = R + 0.7H

I=R+0.7H represents the given situation.

The right answer is Option A.

Paige works at a department store and has a commission rate of 3 percent. Her sales for the quarter were $4,596. If she earns $5
vagabundo [1.1K]
If she gets 3% of what she sells you multiply the decimal form of the percent by the amount she has made:
50*.03=1.5
So she make $1.50 for every $50 of sales, so you multiply the amount she made by her commission each day by the number of days she worked:
1.5*30=45
 
She earned a total of $45<span />
