Ellen’s mom thinks the local weather forecaster correctly predicts the weather 85% of the time, but Ellen thinks it is less than that. The 95% confidence interval for the true proportion of correct forecasts by this weather forecaster is (0.796, 0.862). Is it reasonable to believe the true proportion of times this weather forecaster correctly predicts the weather is less than 85%? Yes, because most of the values in the interval are below 0.85. Yes, because the center of the interval is 0.829, which is less than 0.85. No, because 0.85 is in the interval. No, because there are values in the interval that are greater than 0.85.

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

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.

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].

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.
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

Answer:
Step-by-step explanation:
(g∘f)(4) = g(f(4))

The value of (g · f)(4) is found to be 9.
What is a function?A function is a kind of relation in which the domain(x) has one and only one image in the range(y).
What is a composite function?A composite function is a kind of function that combines two functions in the order in which it is written.
(g ·f)(x) = g(f(x))
In the given problem, we must find (g · f)(4). This is the same as g(f(4)).We have to f(4) and substitute that g(x).
f(x) = -x³
f(4) = -64
Substitute this in g(x):[tex]g(x) = \left| \frac{1}{8} x-1 \right|\\\Rightarrow g(f(x))= \left| \frac{-64}{8}-1 \right|\\=\left| -8-1 \right|\\=\left| -9\right|\\=9[/tex]
Thus, we have found the value of (g · f)(4) to be 9. The correct answer is option C.
