Answer:
m=15
Step-by-step explanation:
BODMAS
6m+6+7-3m=-32
collect like terms
6m-3m+6+7=-32
3m+13=-32
3m=-32-13
3m=45
m=45/3
m=15
Answer:
m = 3
Step-by-step explanation:
6m + 6 + 7(1 - 3m) = -32 (distruibute)
6m + 6 + 7 - 21m = -32 (collect like terms)
-15m + 13 = -32 ( subtract 13 on both sides to get rid of it on the left side)
-15m = -45 (divide by -15 on both sides to get m alone)
m = 3

Statistic Company A Company B Arithmetic Mean 500 600 Median 500 500 Mode 500 300 Standard Deviation 40 20 Mean Absolute Deviation 32 16 Quartile Deviation 25 14 Range 240 120 Sample Size 100 80 The middle 95% of the wires from Company A tested between (________) and (upper) limit. Record ONLY the lower limit as a whole number.
Answer:
The answer is "About 421.6 and 578.4 the middle of 95% of both the wires of the A business checked".
Step-by-step explanation:
The Mean = Median = Mode= 500 for company A
It also will see company A as a regular delivery
Mean > Median > Mode for the business B
Company B would seem to have a correct warped delivery
The value of Z varies in the center of 95% of the wires: [tex](-1.96\ \ from \ \ 1.96)[/tex]
[tex]\text{The lower bound} = Mean - 1.96 \times \sigma[/tex]
[tex]= 500 - 1.96 \times 40 \\\\= 500 - 78.4\\\\= 421.6[/tex]
[tex]\text{The upper limit = Mean} + 1.96 \times \sigma[/tex]
[tex]= 500 + 1.96 \times 40 \\\\= 500 + 78.4 \\\\= 578.4[/tex]

the sum of X and 4 is greater than the difference of 2x and 3 find x
Answer:
x = 7
Step-by-step explanation:
x + 4 > 2x - 3
x by itself = 1x
1x + 4 > 2x - 3
Subtract 1x
1x - 1x + 4 > 2x - 1x -3 =
4 > 1x -3
Add 3
4 + 3 > 1x -3 +3 =
7 > 1x
1x is the same as x
7 = x

Lines AC and BD intersect at E. A figure. What is the measure of angle BEC?
Answer:
Angle BEC = 108°
Step-by-step explanation:
Vertical angles formed when two straight lines intersect are always congruent to each other. That is, the vertical opposite angles formed are of the same measure.
Angle AED = 108°
Angle AED and angle BEC are vertical opposite angles form by intersecting lines, therefore, angle AED = angle BEC.
Angle BEC = 108°

Write an equation of the line shown. Then use the equation to find the value of 2 when y = 185
Answer:
[tex] y = 15x + 20 [/tex]
x = 11, when y = 185
Step-by-step explanation:
Given:
(0, 20);
(2, 50)
Required:
Equation of the line;
Value of x, when y = 185
SOLUTION:
Equation of the line can be written using the slope-intercept formula, given as, [tex] y = mx + b [/tex].
m = slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} =\frac{50 - 20}{2 - 0} = \frac{30}{2} = 15 [/tex]
b = y-intercept = the pointt at which the line cuts the y-axis = 20
Plug in the value into the formula to get the equation:
[tex] y = mx + b [/tex]
[tex] y = 15x + 20 [/tex]
Use this equation to solve for x, when y = 185
[tex] y = 15x + 20 [/tex]
[tex] 185 = 15x + 20 [/tex] (substitution)
[tex] 185 - 20 = 15x + 20 - 20 [/tex]
[tex] 165 = 15x [/tex]
[tex] \frac{165}{15} = \frac{15x}{15} [/tex]
[tex] 11 = x [/tex]
x = 11, when y = 185
A triangle has one angle that measures 56∘ and one angle that measures 63∘. The measure of the triangle's third angle is _____ degrees.
Answer:
61 degrees
Step-by-step explanation:
Let's do this
So we know all the angles measure in a triangle will be 180 degrees
We have 56 and 63
To find the third, let's add and subtract
56+63=119
Now let's subtract from 180
So 180-119=61
The third angle measures 61 degrees
Now let's add them up and see if they total 180 degrees
So 56+63+61=180
Yay, we found the answer!
The answer is 61 degrees.
too young to tat based on a harris poll, among adults who regret getting tattoos, 20% say that they were too young when they got their tattoos. assume that five adults who regret getting tattoos are randomly selected, and find the indicated probability. find the probability that exactly one of the selected adults says that he or she was too young to get tattoos. group of answer choices
Answer:
The probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.
Step-by-step explanation:
Let X denote the number of adults who says that he or she was too young to get tattoos.
The probability of selecting an adults who says that he or she was too young to get tattoos is, p = 0.20.
Five adults who regret getting tattoos are randomly selected.
The events of any of these five adults regretting getting tattoos is independent of each other.
The random variable X follow a Binomial distribution with parameters n = 5 and p = 0.20.
Compute the probability that exactly one of the selected adults says that he or she was too young to get tattoos as follows:
[tex]P(X=x)={5\choose x}(0.20)^{x}(1-0.20)^{5-x}\\\\P(X=1)={5\choose 1}(0.20)^{1}(0.80)^{5-1}\\\\[/tex]
[tex]=5\times 0.20\times 0.4096\\\\=0.4096[/tex]
Thus, the probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.

The high school has 35 teachers and 630 students. What is the ratio of teachers to students?
A: 18:1
B: 1:18
C: 630:35
D: 35:630
Answer:
The ratio of teachers to students is B) 1:18
Step-by-step explanation:
Simply divide the number of teachers to the number of students
630/35 = 18
Therefore the ratio between teachers to students is 1:18, meaning that there is 1 teacher designated for every 18 students.

Graph the line using a point and a slope. Write the equation of each line.
c
a line that contains point (0, −3) and perpendicular to another line whose slope is 2.
Answer:
Graph attached.
Step-by-step explanation:
Line (i) contains point (0, -3)It's perpendicular to line (ii) whose slope is 2The product of slope of line (i) and slope of line (ii) should be equal to -1 (product of slopes of two perpendicular lines = -1)
i.e
Slope of line (i) × 2 = -1
Slope of line (i) = [tex]-\frac{1}{2}[/tex]
To find the equation of line (i), we need another point (x,y) on the line.
Slope (m) = change in y ÷ change in x = [tex]\frac{y - -3}{x - 0} = -\frac{1}{2}[/tex]
y = [tex]-\frac{1}{2} x[/tex] - 3

A car is 180 inches long. A truck is 75% longer than the car. How long is the truck? Explain or show your reasoning.
Answer:
315 inches long
Step-by-step explanation:
180 x .75= 135 <--- that is 75% of 180
then add the two numbers
180 + 135
you add them because the original length of the car is 180 inches and the truck is 75% longer.
180 + 135= 315
find the value of x.

If M is the midpoint of XY and XM=2x+5 and MY=3x-1, then what is the length of MY?
Answer:
If M is mid point then XM = MY
2x +5 = 3x -1
2x - 3x = -1 - 5
-x = -6....so
x = 6
MY = 3(6) -1
MY = 18 -1
MY = 17

If f(2) = 13, which could be the equation for f (x)?
A) f (x) = x2 + 8
B) f(x) = 3x2 +1
C) f(x) = 2x3 + 5
D) f (x) = x2 + x
Only use letter in your answer choice!!!
the answer is B for this question
The equation for f(x) if the independent value is 2 will give a result of 13 is (x) = 3x² + 1
Functions and valuesGiven the expression f(2) = 13, we need to find the function such that when the input value is 2, the output value will be 13.
Using the function f(x) = x² + 8
f(2) = 2² + 8
f(2) = 4 + 8 =12
Using the function f(x) = 3x² + 1
f(2) = 3(2)² + 1
f(2) = 12 + 1 =13
Hence the equation for f(x) if f(2) = 13 is (x) = 3x² + 1

When Alyssa was ten years old, she was twice as old as her horse midnight. If midnight died when he was twenty four years old, how old was Alyssa when Midnight died?
Let Alyssa's horse's age be x .
Then :-
Alyssa's age = 2x
Age of her horse when it died = 24
Alyssa's age when her horse died =
[tex]2x \\ = 2 \times x \\ = 2 \times 24 \\ = 48 \: years[/tex]
∴ Alyssa was 48 years old when her horse Midnight died .
Answer:
29
Step-by-step explanation:
Alyssa was twice the age of midnight so 10 ÷2 =5(age gap)
Midnight died at 24 so Alyssa was 29 that time because
24+5(age gap) =29
