There are 250 freshman at Central High School. You survey 50 randomly selected freshman and find that 38 plan to go to the school party on Friday. How many freshman are likely to be at the party?

190 freshman will probably go to the party

Step-by-step explanation:

first we have to get the probability of a person going

for this we will see those who said they will go on those who asked them

38/50 = 0.76 = 76%

Now we are going to multiply the 0.76 by the 250 people, and we will obtain the probable number of freshman that come to the party

250*0.76 = 190

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
