Answers
Answer:
x = 1,650
Step-by-step explanation:
A real-world problem with a sample and a population is modeled by the proportion 66/100=x/2,500. Use the proportion to complete the sentences.
From the above question, we have to solve for x
Hence, we have the proportion
66/100=x/2,500
Cross Multiply
100 × x = 66 × 2,500
x = 66 × 2,500/100
x = 1,650

Marcos invited 33 guests to his party. So far, 8 guests have replied "will attend" and 9 guests have replied "will not attend". How many guests (g) still need to reply?
Answers
Answer:
16 people haven't replied
Step-by-step explanation:
Add 9 + 8 = 17 and subtract 33 - 17 = 16
If this helps
The guests (g) still need to reply are 16.
What is arithmetic operation?Arithmetic operation is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.
Now it is given that,
Number of guests invited = 33
Number of guests replied "will attend" = 8
Number of guests replied "will not attend" = 9
So, total guest replied = 8 + 9
⇒ total guest replied = 17
Thus, the guests (g) still need to reply = 33 - 17
⇒ the guests (g) still need to reply = 16
Thus, the guests (g) still need to reply are 16.

out of 500 tickets in a raffle, one ticket will win a $650 prize, two tickets will win a $530 prize, and ten ckets will win a $70 prize. The rest will win nothing. If you have a ticket, what is the expected payoff? $
Answers
1/500 = 650 (1.30)
2/500 = 350 (1.40)
10/500 = 70 (1.40)
487/500 = 0 (0)
Payoff 1.3 + 1.4 + 1.4 = $4.10
Subtract the cost of the ticket from that

Veronica took her friend out for a birthday dinner. She purchased an appetizer
for $7.95, two entrées for $12.95 and $15.95, two drinks for $3.50 each, and two
desserts for $6.95 each. She had a 25% off coupon. A sales-tax rate of 9.25% was
then added. How much was the meal? If Veronica left a 20% tip, how much did
she leave for the tip? *
Answers
Answer:
Veronica left a tip of $6.87
Step-by-step explanation:
3.50×2= 7
6.95×2= 13.9
7.95+12.95+15.95+7+13.9 = 41.8
0.25×41.8= 10.45
41.8-10.45= 31.35
0.0925×31.35 = 3
31.35+3 = 34.35
0.20×34.35 = 6.87

[tex]\frac{55}{14}[/tex]
Step-by-step explanation:
First, we convert the mixed numbers into improper fractions: [tex]1\frac{3}{7} =\frac{10}{7}[/tex], and [tex]2\frac{3}{4}=\frac{11}{4}[/tex]. Now, we multiply the fraction using the multiplication rule, [tex]\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}[/tex]: [tex]\frac{10}{7} \times \frac{11}{4} = \frac{110}{28} = \frac{55}{14}[/tex].
Thus, the product of the two given fractions is 55/14.
