Ummmm that’s a triangle but I guess I’ll solve for both 7x7= 49/2= 24.5 triangle. Polygon is different but I guess if the perimeter and line to the center is both 7 okay 7x5= 35x7= 245/2= 122.5 cause triangle is wxL /2 and polygon is AxP/2 soooo I hope this helped

Create a probability model for the outcome of performing 2 spins. What is the probability of NOT landing on yellow or red at all

Mamont248 [21]

Using the concept of probability, the probability of not landing on yellow or red at all is 1/4.

Creating a square model of the two spins :

Red(R) ; Blue(B) ; Green(G) ; Yellow(Y)

___ R ___ B ___ G ___ Y

R_ RR __ RB __ RG __ RY

B_ BR __ BB __ BG __ BY

G_ GR __GB __ GG __GY

Y_ YR __ YB __ YG __ YY

Sample space = 4² = 16

Combinations without red and yellow :

{BB, BG, GB, GG}
Number of selections without red or yellow = 4

Recall :

Probability = required outcome / Total possible outcomes

P(without Red or Yellow) = 4/16 = 1/4

Hence, the probability of not landing on yellow or red at all is 1/4.

A grocery store bought milk for $2.80 $⁢2.80 per half gallon and stored it in two refrigerators. During the night, one refrigera

harkovskaia [24]

Let x represent the number of half-gallons purchased by the store. Then x-13 is the number sold, and 2.80x is the store's cost. The revenue is 4.06(x-13) and the difference between that and cost is the profit.

... 4.06(x -13) -2.80x = 63.14

... 1.26x - 52.78 = 63.14 . . . . eliminate parentheses, collect terms

... 1.26x = 115.92 . . . . . . . . . . add 52.78

... x = 115.92/1.26 = 92 . . . . . divide by the coefficient of x

The store purchased 92 half-gallons of milk.

Answer:

FICA tax should his employer withhold be $24.92 .

Option (D) is correct .

Step-by-step explanation:

As given

Bill’s FICA tax is 7.65% of his earnings of 325.78 per week.

7.65 % is written in the decimal form.

$= \frac{7.65}{100}$

= 0.0765

FICA tax price = 0.0765 × Earning of a week

Putting values in the above

FICA tax price = 0.0765 × 325.78

= $ 24.92 (Approx)

Therefore the FICA tax should his employer withhold be $24.92 .

Option (D) is correct .
