27 - 4x + -7 ( 1 + 3x)
Answer:
-25x + 20
Step-by-step explanation:
I am going to assume by the lack of instructions, you wanted this simplified. We need to start by combining the -7 into the two terms in the paranthesis:
27 -4x -7 -21x
We can now combine like terms to simplify:
-25x + 20
27-4x+-7(1+3x)
27 - 4x - 7(1+3x)
27 - 4x - 7 - 21x
-25x + 20
Which equation has the solution x = 9?

4+ 5x = 18
81 – 3 = 6
х
2x – 3 = 15
24 – 2x = 13
3x + 2 = 25
Answer:
2x – 3 = 15
Step-by-step explanation:
2 * 9 = 18 - 3 = 15. correct
+7 = 8, no I don't really now what you mean by this...
81 - 3 = 6x? > (81 - 3 = 78) = (6 * 9 = 54), no, please tell me if I'm interpreting this right.
4 + 5x = 18 > 5 * 9 = 45 + 4 = 49, no
2 * 9 = 18, 24 - 18 = 6, no
3 * 9 = 27 + 2 = 29, no

The mean output of a certain type of amplifier is 466 watts with a standard deviation of 10 watts. If 32 amplifiers are sampled, what is the probability that the mean of the sample would differ from the population mean by less than 1.6 watts? Round your answer to four decimal places.
Answer:
0.8186
Step-by-step explanation:
The formula to use to solve this question is given as:
z = (x-μ)/σ/√n, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
n is the random number of samples
P(z < (x-μ)/σ/√n)
(x-μ) = 1.6 watts
σ = 10 watts
n = 32 amplifiers
Hence,
P(z < 1.6/10/√32)
P(z < 1.6/1.767766953)
P(z < 0.9050966799)
Approximately to 2 decimal places)
P(z < 0.91)
= 0.81859
Rounded to four decimal places, the probability that the mean of the sample would differ from the population mean by less than 1.6 watts is 0.8186.
A hotel manager records the number of bookings made at various prices during July.
What type of correlation does the graph show?
A. strong positive correlation
B. weak positive correlation
C. strong negative correlation
D. weak negative correlation
E. no correlation
Answer:
C. strong negative correlation
Step-by-step explanation:
I would say the answer is C. a strong negative correlation.
Firstly, the graph is 'going downwards', meaning that the relationship is negative. This is because one variable decreases when the other is increased. I think it is a strong relationship because the trend is quite clear through the points and the slope is moderately steep.
Hope this helped!
Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a
mean of 100 and a standard deviation of 15.
106 124
The area of the shaded region is (Round to four decimal places as needed.)
Answer:
The area of the shaded region is 0.2898.
Step-by-step explanation:
Let X represent the IQ scores of adults.
It is provided that [tex]X\sim N(100,15^{2})[/tex].
Compute the probability of an adult having an IQ between 106 and 124 as follows:
[tex]P(106<X<124)=P(\frac{106-100}{15}<\frac{X-\mu}{\sigma}<\frac{124-100}{15})[/tex]
[tex]=P(0.40<Z<1.60)\\=P(Z<1.60)-P(Z<0.40)\\=0.94520-0.65542\\=0.28978\\\approx 0.2898[/tex]
*Use a z-table.
Thus, the area of the shaded region is 0.2898.

A triangle has a base length of 10 inches and a height of 4 inches.
What is the area of the triangle?
Answer:
No, The answer is 20. Remember area of triangle equals 1/2bh (or half of base and height multiplied.)
The area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.
What is area of a triangle?
The area of a triangle is one half the product of its base multiplied by height. Mathematically -
Area [Δ] = 1/2 x base x height
Given is a triangle (Δ) has a base length of 10 inches and a height of 4 inches.
We can write -
Base Length [B] = 10 inches
Height of triangle [H] = 4 inches
Area of triangle (Δ) = 1/2 x B x H
A(Δ) = 1/2 x B x H
A(Δ) = 1/2 x 10 x 4
A(Δ) = 20 square inches
Therefore, the area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.

The company is interested in which confidence intervals associated with 1 (very satisfied) contain the proportion 0.25, or 25%. Determine which confidence levels satisfy this. (Select all that apply.)
Hi, you've asked an incomplete question. However, I provided a brief explanation about confidence interval and confidence level.
Explanation:
The term confidence interval and confidence level are not the same but they are related. Confidence interval refers to a range of values that makes up part of the statistic's mean data which contains an unknown population parameter.
However, the Confidence level is the level of certainty that the confidence interval would contain the true population parameter if a random sample is drawn.

The variables x and y are related proportionally. When x = 8, y = 20. Find y when x = 80.
Answer:
y = 200
Step-by-step explanation:
Use the equation y = kx, where k is a constant.
Plug in the given x and y values, then solve for k:
y = kx
20 = k(8)
2.5 = k
Then, plug in k and the given x value, and find y:
y = 2.5x
y = 2.5(80)
y = 200
So, y = 200 when x = 80

Factor each of the following quadratic expression.
1. x² + x
2. 5x2 - 25x
3. x2 - 16
4. x² + 4x + 4
5. x2 - 5x + 6
Step-by-step explanation:
Given expressions:
1. x² + x
2. 5x² - 25x
3. x² - 16
4. x² + 4x + 4
5. x² - 5x + 6
Problem: Factor each of the quadratic expression
Solution:
A quadratic expression is an expression whose highest power is two.
1. x² + x
For this expression:
x² + x
Factorizing x since it is a common term;
x(x + 1)
2. 5x² - 25x
For this expression;
Factorize 5x since it common to both of them;
5x(x - 5)
3. x² - 16
For this expression;
Apply the differences of two squares;
x² - 16
x² - 4²;
Note; x² - y² = (x-y)(x+y)
So, x² - 4² = (x-4)(x + 4)
4. x² + 4x + 4
To solve this,
Find two numbers whose product will be 4 and sum also 4;
x² + 4x + 4 = x² + 2x + 2x + 4
= x(x + 2) + 2(x + 2)
= (x + 2)(x + 2)
5. x² - 5x + 6
To factorize this expression, simply find two numbers whose sum is -5 and product is 6;
x² - 5x + 6 = x² - 3x - 2x + 6
= x (x - 3) -2(x - 3)
= (x -2)(x-3)
