(b=9) help now please I'm failing
Answer:
Step-by-step explanation:
Move all terms containing b to the left, all other terms to the right. Add '81' to each side of the equation. -81 + 81 + b 2 = 0 + 81 Combine like terms: -81 + 81 = 0 0 + b 2 = 0 + 81 b 2 = 0 + 81 Combine like terms: 0 + 81 = 81 b 2 = 81 Simplifying b 2 = 81 Take the square root of each side: b = {-9, 9}

Answer:
The correct answer is X=5
I'm 10000000000% sure
Answer:
x = 5
Step-by-step explanation:
First, to get rid of the fraction, multiply both sides of the equation by x.
— (14.8/x + 2.4) * x = 5.36 * x
— 14.8 + 2.4x = 5.36x
Next, subtract 2.4x from both sides of the equation.
— 14.8 + 2.4x - 2.4x = 5.36x - 2.4x
— 14.8 = 2.96x
Now, divide both sides of the equation by 2.96.
— 14.8/2.96 = 2.96x/2.96
— 5 = x
Subtract: 9-7
Subtracting 9-7=2

The statistical question is "How many pets does Alisha have at home?''.
The correct option is Question 1.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Simply expressed, a statistical question is one that is supported by data and facts.
From the given choices:

Questions :
(4a) Write a multiplication equation AND a division equation to represent this statement. "There are 12 fourths in 3.".
(4b) Write a multiplication equation and a division equation to represent this diagram.
Answer:
12/4 * 3 or 3 ÷ 12/4
Step-by-step explanation:
Don't worry, I got you covered.
First, you examine the words in the sentence. After you look at the key-words, which would be "12 fourths in 3." This would translate to 12/4 into 3. Here's the examples.
Start by dividing rather than multiplying for your first equation.
3 ÷ 12/4. If you want 3 to be equal to 12/4 in division, you want to take the largest number and divide it into the smaller number. In this case, the large number would be 3 while the small number would be 12/4. It still makes it correct, despite you changing the problem a bit.
This would get you the easiest way to use your division.
Finally, try making a multiplication problem. If you want there to be 3 equal to 12/4, another justification could be 12/4 * 3. This would keep the problem true, while still solving the missing equation.

There are 120 students at Francis Howell North High School. Mr. Willott conducts a poll that asks 20 randomly selected students how many hours of sleep they got last night. They find that the mean amount of sleep is 6.7 hours. The population standard deviation is σ = 2 hours. Can we estimate the standard deviation of the sampling distribution of means by using σ divided by the square root of n (2/sqrt(20) = 0.557 hours)?
Answer:
Yes
Step-by-step explanation:
The central limit theorem says that If a random variable X from a population has mean u and finite variance σ² , then the sampling distribution of the sample mean X~ approaches a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.
It is interesting to note that we have neither assumed that the distribution of X is continuous nor we have said anything about the shape of the distribution , whereas the limiting distribution of X is continuous and normal. Thus the distribution of the sample means regardless of the shape of the population having a finite variance , is approximately normal with mean u and variance σ²/n .
Therefore
(standard deviation/ √sample size)²= variance / n
2/ √20
= 2/4.472
=0.44721
The sampling distribution of X` is therefore approximately normal with mean ux=u and σx =σ/n
Yes, we estimate the standard deviation of the sampling distribution of means by using σ divided by the square root of n and this can be determined by finding the mean and standard deviation for the distribution of the sample means.

Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.15 and a standard deviation of 1.52. Using the empirical rule, what percentage of American women have shoe sizes that are less than 11.19
Answer:
97.5% of American women have shoe sized less than 11.19
Step-by-step explanation:
Here, we want to use the empirical rule to find the percentage of women with shoe sizes less than 11.19
The first thing we shall do here is to find the z-score
Mathematically, that will be calculated using the formula;
z = (x-mean)/SD
z = (11.19-8.15)/1.52
z = 2
We can see that the given value is 2 standard deviation away to the right of mean
So, we want to get the percentage that is between the mean and two standard deviations away from it using the empirical rule
So according to the empirical rule
The percentage will be
100-2.35-0.15
= 100-2.5 = 97.5%

Answer:
AC = 4[tex]\sqrt{13}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AC² + 9² = 17²
AC² + 81 = 289 ( subtract 81 from both sides )
AC² = 208 ( take the square root of both sides )
AC = [tex]\sqrt{208}[/tex] = 4[tex]\sqrt{13}[/tex] ← exact value
≈ 14.42 ( to 2 dec. places )
