Step-by-step explanation
3 x 2.50 = 7.50
7.50 x 0.06 = 0.45
7.50 + 0.45 = 7.95

9-4(x+4)<=7+4(5x+7)
Let's solve your inequality step-by-step.
9−4(x+4)≤7+4(5x+7)
Step 1: Simplify both sides of the inequality.
−4x−7≤20x+35
Step 2: Subtract 20x from both sides.
−4x−7−20x≤20x+35−20x
−24x−7≤35
Step 3: Add 7 to both sides.
−24x−7+7≤35+7
−24x≤42

Find the 5th term for -12,-7,-2,3
a normal distribution has a mean of 10 and a standard deviation of 1 what is the probability of selecting a number between 7 and 13?
Answer: 0.9974
Step-by-step explanation:
Let X be the random variable that follows the normal distribution \.
If mean ([tex]\mu[/tex]) = 10 and standard deviation ([tex]\sigma[/tex]) =1
then, the probability of selecting a number between 7 and 13 = [tex]P(7<X<13)[/tex]
[tex]=P(\dfrac{7-10}{1}<\dfrac{X-\mu}{\sigma}<\dfrac{13-10}{1})[/tex]
[tex]=P(-3<z<3)[/tex] [Since [tex]z=\dfrac{X-\mu}{\sigma}[/tex]]
[tex]=P(z<3)-P(z<-3) \ \ \ [P(z_1<Z<z_2)=P(Z<z_2)-P(Z<z_1)]\\\\= P(z<3)-(1-P(z<3))\ \ \ [P(Z<-z)=1-P(Z<z)]\\\\=2P(z<3)-1\\\\=2(0.9987)-1\ \ [\text{By p-value table}]\\\\= 0.9974[/tex]
Hence, the probability of selecting a number between 7 and 13 is 0.9974.

Answer:
x=5 over 2 (it's a fraction)
Step-by-step explanation:
STEP 1 distribute : 4-1 (2x+4)=5
4-2x-4=5
STEP 2 subtract: 4-2x-4=5
-2x=5
STEP 3 divide both sides of the equation by the same term:
-2x=5
-2x 5
----- ------
-2 -2
STEP 4 simplify:
cancel the terms that are both the numerator and denominator
divide the numbers
x= - 5 over 2 (fraction)

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.
Triangle A,B,C with vertices at A(negative 3, 6), B(2, 9), and C(1, 1)
Note: Consider we need to find the vertices of the triangle A'B'C'
Given:
Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.
Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).
To find:
The vertices of the triangle A'B'C'.
Solution:
If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then
[tex](x,y)\to (y,-x)[/tex]
Using this rule, we get
[tex]A(-3,6)\to A'(6,3)[/tex]
[tex]B(2,9)\to B'(9,-2)[/tex]
[tex]C(1,1)\to C'(1,-1)[/tex]
Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).

Here is a quote from an NPR news article: "On average, working-age adults were eating about 78 fewer calories per day in 2010, compared with five years earlier. The new report is based on data from the National Health and Nutrition Examination Survey, which collects details on eating habits and other health-related information from a nationally representative sample of about 10,000 people in the U.S." Which of the following is TRUE about the numerical value 78?
a. It is an anecdote.
b. It is a parameter.
c. It is a simulation.
d. It is a statistic.
Answer:
The answer is "Option d".
Step-by-step explanation:
It involves the use of quantitative templates, diagrams, or summaries in such a given set of experimental data or real-liability for research. This research method is used for gathering, analyzing, assessing, or making judgments.
The statistics are mostly a summary description and the entire nation is represented in a parameter. It is 78 figure is a statistical figure based on a survey of 10,000 people, that's why choice d is correct.Rachel and three friends were going to the movies.

My question is
6( 2x - 3)-8=-2
Answer:
x = 2
Step-by-step explanation:
Apply the distributed property: 12x - 18 - 8 = -2Combine like terms: 12x - 26 = -2Add 26 to each side, so it now looks like this: 12x = 24Divide each side by 12 to cancel out the 12 next to x. It should now look like this: x = 2I hope this helps!

4 students is blank% of 20 students?
Answer:
4 students is 20% of 20 students.
Step-by-step explanation:
We can say that 20 students represent 100% and that 4 students represent x% of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 %
4 students are 20 percent of 20 students.
What is the percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
We can say that 20 students represent 100% and that 4 students represent x% of all students.
Thus, we can use the proportion:
20 : 4 = 100: x, or 20 / 4 = 100 / x.
cross multiply
20 x = 4 * 100
20 x = 400
x = 400: 20
x = 20 %.
therefore, we can say that 4 students are 20 percent of 20 students.

Solve for x: |2x + 12| = 18
x = 3, x = −3
x = 3, x = −15
x = 15, x = −15
x = −3, x = 15
Answer:
x = 3 x = -15
Step-by-step explanation:
|2x + 12| = 18
There are two solutions to an absolute value equation, one positive and one negative
2x+12 = 18 2x+12 = -18
Subtract 12 from each side
2x+12-12 = 18-12 2x+12-12 = -18-12
2x = 6 2x = -30
Divide by 2
2x/2 = 6/2 2x/2 = -30/2
x = 3 x = -15
