What is the slope between (-14,-12),(7,17)
Answer:
[tex]let, slope=m[/tex]
[tex]Therefore,m = 29 / 21 = 1.38095[/tex]
Answer:
Slope ≈ 1.38
Step-by-step explanation:
GIVEN :-
(x₁ , y₁) = (-14 , -12)(x₂ , y₂) = (7 , 17)TO FIND :-
Slope between the given pointsSOLUTION :-
Formula for slope = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Using this formula ,
[tex]Slope = \frac{17 - (-12)}{7 - (-14)}[/tex]
[tex]= \frac{17 + 12}{7 + 14}[/tex]
[tex]= \frac{29}{21}[/tex]
[tex]= 1.38 (appx.)[/tex]
the the product of 334 and k decreased by 68 is 65
Answer:
Step-by-step explanation:
334k - 68 = 65
+ 68 +68 Add 68 because addition is the opposite of subtraction.
334k = 133 Simplify
/334 /334 divide by 334 because it is the opposite of multiplication.
k = 0.39820359281
A group consisting of 6 people is to be selected from eight parents and four teachers.
Find the probability of selecting three parents and three teachers.
Answer:
9/32 or 0.28125
Step-by-step explanation:
8 parents and 4 teachers
There are 12 possible outcomes.
probability = # of favorable outcomes / # of possible outcomes
Let's do the teachers first.
There are 4 teachers, and we are finding the probability for 3 of them being picked.
Therefore,
P = 3/4
Now let's do the parents.
There are 8 parents, and we want 3.
Therefore,
P = 3/8
Now, we do [tex]\frac{3}{4} *\frac{3}{8} = \frac{9}{32}[/tex]
Therefore, the chance of 3 teachers and 3 parents being picked out of 4 teachers and 8 parents is 9/32, or in decimal form 0.28125.

10. Find the quotient of 3808 and 200. Write the answer as a mixed number
in simplest form.
Answer:
19.04 = 19 1/25
Hope This Helped;)
The quotient of 3808 and 200 in the form of a mixed number
in simplest form is 19 1/25.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The numbers are 3808 and 200
After dividing:
= 3808 ÷ 200
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
Or
= 3808/200
Divide both the numerator and denominator by the GCD
= 476/25
= 19 1/25
Thus, the quotient of 3808 and 200 in the form of a mixed number
in simplest form is 19 1/25.

Answer:
[tex] \frac{ - (5.8 - 3(3.2))}{ {( - .2)}^{2} } + 3 \\ = \frac{ - (5.8 - 9.6)}{.04} + 3 \\ = \frac{ - ( - 3.8)}{.04} + 3 \\ = \frac{3.8}{.04} + 3 \\ = 95 + 3 \\ = 98 \\ thank \: you[/tex]
Answer:
Below
Step-by-step explanation:
First we will evaluate the brackets (BEDMAS)
- (5.8 - 9.6) / (-0.2)^2 + 3
- ( -3.8 ) / ( 0.04) + 3
Because there is a negative sign on both the outside and inside of a bracket, that number becomes positive
( 3.8 ) / ( 0.04 ) + 3
Calculate this :
= 95 + 3
= 98

Work Shown:
(f - g)(x) = f(x) - g(x)
(f - g)(x) = (3x-1) - (x+2)
(f - g)(x) = 3x-1 - x-2
(f - g)(x) = (3x-x) + (-1-2)
(f - g)(x) = 2x-3

y=mx+b m= rise/run = change in Y/change in x/ b= y-intecept.
Answer:
y = -[tex]\frac{2}{8}[/tex] + 5
Step-by-step explanation:
You have all that you need
(y = mx+b, m= rise/run which is the change in y/change in x, b = y-intercept.)
so now we just need to put it to use!
Let's take y = mx + b and break it into two parts. We need the b and the m. The b is easier, because we can conclude by looking at the graph it is equal too 5. Here is our equation so far:
y = mx + 5
Now we need to solve for m:
[tex]\frac{rise}{run} = \frac{2}{8}[/tex]
The line is going dowards, so the slope (m) is negative.
Here is our final answer:
y = -[tex]\frac{2}{8}[/tex] + 5

Answer:
D
Step-by-step explanation:
The absolute value function has its vertex at (1, 3). It is scaled by a factor of -2, so its transformation of the parent function f(x) = |x| will be ...
-2f(x -1) +3 = -2|x -1| +3
This represents the left side of the equation you're seeking.
The right side equation is the equation of a line with slope 2/5 and y-intercept -2.2 = -11/5.
The equation that has both the left side and the right side correct is ...
D. -2|x -1| +3 = 2/5x -11/5
A politician claims that he is supported by a clear majority of voters. In a recent survey, 38 out of 60 randomly selected voters indicated that they would vote for the politician. (You may find it useful to reference the z table.)
a. Select the null and the alternative hypotheses.
multiple choice 1
H0: p = 0.50; HA: p ≠ 0.50
H0: p ≤ 0.50; HA: p > 0.50
H0: p ≥ 0.50; HA: p < 0.50
b. Calculate the sample proportion. (Round your answer to 2 decimal places.)
c. Calculate the value of test statistic. (Round final answer to 2 decimal places.)
d. Find the p-value.
multiple choice 2
0.025 p-value < 0.05
0.05 p-value < 0.10
p-value 0.10
p-value < 0.01
0.01 p-value < 0.025
e. At the 5% level of significance, what is the conclusion?
multiple choice 3
Do not reject H0; the politician’s claim is not supported by the data.
Do not reject H0; the politician’s claim is supported by the data.
Reject H0; the politician’s claim is not supported by the data.
Reject H0; the politician’s claim is supported by the data.
Testing the hypothesis for the proportion, it is found that:
a) H0: p ≤ 0.50; HA: p > 0.50
b) The sample proportion is [tex]\pi = 0.6333[/tex].
c) The test statistic is [tex]z = 2.07[/tex].
d) The p-value of the test is of 0.0192.
e) Reject H0; the politician’s claim is supported by the data.
Item a:
At the null hypothesis, we test that the politician does not have the majority, thus:
[tex]H_0: p \leq 0.5[/tex]
At the alternative hypothesis, we test that he/she does have the majority, thus:
[tex]H_1: p > 0.5[/tex]
Item b:
38 out of 60, thus:
[tex]\pi = \frac{38}{60} = 0.6333[/tex]
The sample proportion is [tex]\pi = 0.6333[/tex].
Item c:
The test statistic is:
[tex]z = \frac{\pi - p}{\sqrt{\frac{p(1 - p)}{n}}}[/tex]
For this problem, [tex]\pi = 0.6333, p = 0.5, n = 60[/tex], thus:
[tex]z = \frac{0.6333 - 0.5}{\sqrt{\frac{0.5(0.5)}{60}}}[/tex]
[tex]z = 2.07[/tex]
The test statistic is [tex]z = 2.07[/tex].
Item d:
The p-value of the test is the probability of finding a sample proportion above 0.6333, which is 1 subtracted by the p-value of z = 2.07.
Looking at the z-table, z = 2.07 has a p-value of 0.9808.
1 - 0.9808 = 0.0192
The p-value of the test is of 0.0192.
Item e:
The p-value of the test is of 0.0192 < 0.05, thus, his claim is supported by the data, and we reject the null hypothesis. Then, the correct option is:
Reject H0; the politician’s claim is supported by the data.

What transformations take place by graphing the function below in respect to its parent function? Check all that apply.
Answer:
y = x² is the parent
y = 3/2(x+7)²+2 shifts 7 u left, up 2 u, and has vertical compression
Answer:
Right 7 unitsUp 2 unitsVertical StretchStep-by-step explanation:
Given the function, f(x) = 3/2(x + 7)² + 2,
where:
a = 3/2
vertex (h, k ) = (7, 2)
The value of a determines whether the graph opens up or down. The value of a also makes the parent function wider or narrower (vertical stretch by a factor of a ). If a > 1, the graph is narrower than the parent function. The value of h determines how far left or right the parent function is translated. If h is positive, the function is translated h units to the right. The value of k determines how far up or down the parent function is translated. If k is positive, the function is translated k units up.
Given these descriptions, we can assume that:
The function is vertically translated by 2 units upward. The function is horizontally translated by 7 units to the right.Vertical stretch by a factor of 3/2 (or 1.5).Please mark my answers as the Brainliest, if you find my explanations helpful :)
