rewrite 9x9x9x9x9 using an exponent
Answer:
9^5
Step-by-step explanation:
9 x 9 x 9 x 9 x 9 can be written as an exponent form 9⁵.
To rewrite 9 x 9 x 9 x 9 x 9 using an exponent, we can represent the repeated multiplication with the base 9 raised to the power of 5. Here's how:
9 x 9 x 9 x 9 x 9 = 9⁵
In this expression, the base is 9, and the exponent is 5. The base represents the number being multiplied repeatedly, and the exponent represents the number of times it is multiplied.
Using the exponent notation, we can simplify and express the result more concisely. The exponent 5 indicates that the base 9 is multiplied by itself five times.
Therefore, 9 x 9 x 9 x 9 x 9 can be written as 9⁵.

From Barbie dolls to runway models, women in Western countries are exposed to unrealistically thin and arguably unhealthy body standards for their gender. A body mass index (BMI) between 18.5 and 24.9 is considered healthy. Using a 3D computer avatar, participants built what they considered the ideal body of an adult of their own gender. Below appears a summary of the results for a sample of 40 female heterosexual Caucasian undergraduate students from British universities that had been recruited by the researchers. Mean BMI was recorded to be 18.85 with standard deviation 1.75. Does the data provide evidence that young Caucasian women in British Universities, on average, aim for an unhealthy ideal body type (corresponding to a BMI less than 18.5)? Use α = 0.10.
Required:
a. Construct a 99% confidence interval for the mean BMI for young Caucasian women in British universities using R. Use at least 2 decimals in your answer.
b. Would a 99% CI (for the mean BMI) constructed using a smaller sample than the one used for part a) tend to be wider or narrower? Explain.
Answer:
(18.1361 ; 19.5639) ;
using a smaller sample will widen the margin
Step-by-step explanation:
Given :
Xbar = 18.85
Standard deviation, s = 1.75
Sample size, n = 40
Confidence interval is obtained using the relation :
Xbar ± Margin of error
Margin of Error = Zcritical * s/ √n
Zcritical at 99% = 2.58
Margin of error = 2.58 * (1.75/√40) = 0.7139
Lower boundary = 18.85 - 0.7139 = 18.1361
Upper boundary = 18.85 + 0.7139 = 19.5639
(18.1361 ; 19.5639)
B.)
The sample size, n being the denominator in the margin error formula increases the error value as it reduces or decreases in value Hence widens the interval. Conversely, increasing the sample size reduces the error margin value and ultimately narrows the interval.
Therefore, using a smaller sample will widen the margin

Answer:
90°-33°=57°
57=2x+1
-1. -1
56=2x divide both sides by 2
28=x
x =28
Answer:
x = 28
Step-by-step explanation:
Both of these would add up to 90 degrees.
Equation → 2x + 1 + 33 = 90
Add like terms → 2x + 34 = 90
Subtract both sides by 34 → 2x + 34 - 34 = 90 - 34
Divide both sides by 2 → 2x = 56
→ x = 28

x^3=27 what is the value of x?
Answer:
x = 3
Step-by-step explanation:
3*3*3 = 9*3 = 27
Step-by-step explanation:
Let's solve your equation step-by-step.
[tex]x^3 =27[/tex]
Step 1: Take cube root.
[tex]x = (27)^(1/3)[/tex]
[tex]x=3[/tex]
Explanation in words (Short Form)
- Move the variable to the left and the other values to the right to determine the value of x. To ascertain the outcome, simplify the values.
- In this equation (x^3=27), we can solve this equation by taking the cube root and then ascertaining the outcome. The answer will result as x = 3 at the end for the following equation: x^3=27 to finding the value for x.
Answer:
[tex]x=3[/tex]

This is a regular octagon. (It has 8 equal sides). You have enough information to find the area of 1 triangle.label the bottom line as 5.Draw two lines from the center to each end of the bottom 5 inch line.That gives you 1 triangle. Find the area of that 1 triangle.Area = 1/2 b * hb = 5h = 6Area = 1/2 * 5 * 6Area = 15.Now here's the actual answer.You have 8 such triangles. The area of the octagon is 8 * 15 = 120 square inches.The annual profits for a company are given in the following table where X represents the number of years since 2004 and Y represents the profit in thousands of dollars write the linear regression equation that represents the set of data rounding are Koi fishes to the nearest 10th using this equation find the projected profit in thousands of dollars for 2016 rounded to the nearest thousand dollars

Choose all of the statements that indicate long-term advantages in placing a larger down payment on a car loan received from a bank.
A). Using a larger down payment often results in lower interest rates on the loan for the vehicle.
B) The amount of money placed upfront on a car loan is usually rebated back to the borrower at the end of the loan.
C) Placing a larger down payment on the loan typically lessens the total amount required to be paid back on the loan.
Eliminate

From the bar chart, we can see that the the interval 130-150 has two bars in it:
Interval 130-140 with the highest frequency of 5
Interval 140-150 with frequency of 2
Therefore to find the percentage between 130-150 we add up the frequencies 2+5=7 and divide by the total frequency of 15 people all multiplied by 100
=7/15×100= 46.67%
Percentage of participants with heart rate between 130 and 150 =46.67%

Answer: The answer is B, 5/12.
hope this helped :)
Answer:
B. 5/12
Step-by-step explanation:
2/3 x 5/8 = 10/24
The greatest common factor of 10 and 24 is 2.
Since the GCF is 2,
We divide the numerator and denominator by 2 and get 5/12.
Therefore, the simplified fraction of 10/24 is 5/12.

Answer:
72 mi is the answer.
Step-by-step explanation:
a = 30 mi
b = ?
c = 78 mi
According to the Pythagoras theorem,
a² + b² = c²
30² + b² = 78²
900 + b² = 6084
b² = 6084 - 900
b² = 5184
b = 72 mi
∴ the eastbound airplane has travelled 72 mi.
