Answer:
∠ RST = 72°
Step-by-step explanation:
∠ RST and 4x - 24 are alternate exterior angles and congruent, thus
4x - 24 = 3x ( subtract 3x from both sides )
x - 24 = 0 ( add 24 to both sides )
x = 24
Thus
∠ RST = 3x = 3 × 24 = 72°

the graph of the absolute value parent function, f(x) = |x|, is stretched horizontally by a factor of 5 to create the graph of g(x). what is the function of g(x)?
a. g(x) = |x+5|
b. g(x) = |1/5 x|
c. g(x) = |5x|
d. g(x) = 5 |x|
Answer: I’m thinking the answer is B
Step-by-step explanation:
Transformations are used to move a function from one position to another. The function of g(x) is [tex]g(x) = |\frac x5|[/tex]
Given that:
[tex]f(x) = |x|[/tex]
The rule of a horizontal stretch by factor k is:
[tex](x,y) \to (\frac xk,y)[/tex]
This means that:
[tex]g(x) = f(\frac xk)[/tex]
In this case, [tex]k = 5[/tex]
So, we have:
[tex]g(x) = f(\frac x5)[/tex]
Calculate [tex]f(\frac x5)[/tex]
[tex]f(\frac x5) = |\frac x5|[/tex]
Hence, the function of g(x) is
[tex]g(x) = |\frac x5|[/tex]

Imagine that you are doing an exhaustive study on the children in all of the daycares in your school district. You are particularly interested in how much time children spend in active play on weekends. You find that for this population of 2,431 children, the average number of minutes spent in active play on weekends is μ = 65.87, with a standard deviation of σ = 87.08. You select a random sample of 25 children of daycare age in this same school district. In this sample, you find that the average number of minutes the children spend in active play on weekends is M = 59.28, with a standard deviation of s = 95.79.
The difference between M and mu is due to the sampling error is ______.
Answer: The difference between M and mu is due to the sampling error is -6.59 .
Step-by-step explanation:
As per given:
in population, the average number of minutes spent in active play on weekends is μ = 65.87
In sample, the average number of minutes the children spend in active play on weekends is M = 59.28
Now, the difference between M and μ is due to the sampling error is M- μ
= 59.28 - 65.87
= -6.59
So, the difference between M and mu is due to the sampling error is -6.59 .
pls help me with this i will give crown
Answer:
C
Step-by-step explanation:
The easiest way to solve this would be to find the difference between the numbers. We can do [tex]-3-(-9)[/tex] to find the difference of [tex]6[/tex]. We can then make sure this is true for the rest of the sequence by adding 6 to each number.
[tex]-9+6=-3[/tex]
[tex]-3+6=3[/tex]
[tex]3+6=9[/tex]
[tex]9+6=15[/tex]
Now that we've verified that this is true, we know the answer is C

Solving Equations.
It is estimated % of all adults in United States invest in stocks and that % of U.S. adults have investments in fixed income instruments (savings accounts, bonds, etc.). It is also estimated that % of U.S. adults have investments in both stocks and fixed income instruments. (a) What is the probability that a randomly chosen stock investor also invests in fixed income instruments? Round your answer to decimal places. (b) What is the probability that a randomly chosen U.S. adult invests in stocks, given that s/he invests in fixed income instruments?
Complete question :
It is estimated 28% of all adults in United States invest in stocks and that 85% of U.S. adults have investments in fixed income instruments (savings accounts, bonds, etc.). It is also estimated that 26% of U.S. adults have investments in both stocks and fixed income instruments. (a) What is the probability that a randomly chosen stock investor also invests in fixed income instruments? Round your answer to decimal places. (b) What is the probability that a randomly chosen U.S. adult invests in stocks, given that s/he invests in fixed income instruments?
Answer:
0.929 ; 0.306
Step-by-step explanation:
Using the information:
P(stock) = P(s) = 28% = 0.28
P(fixed income) = P(f) = 0.85
P(stock and fixed income) = p(SnF) = 26%
a) What is the probability that a randomly chosen stock investor also invests in fixed income instruments? Round your answer to decimal places.
P(F|S) = p(FnS) / p(s)
= 0.26 / 0.28
= 0.9285
= 0.929
(b) What is the probability that a randomly chosen U.S. adult invests in stocks, given that s/he invests in fixed income instruments?
P(s|f) = p(SnF) / p(f)
P(S|F) = 0.26 / 0.85 = 0.3058823
P(S¦F) = 0.306 (to 3 decimal places)
Examine triangle ABC.
Triangle A B C. Angle B is 79 degrees. Exterior angle to A is (x + 5) degrees and the exterior angle to C is x degrees. What is the value of x?
37
48
127
138
Answer:
x=127
Step-by-step explanation:
total sum of all angle of triangle is 180 degree
Now,
taking angle A let interior angle be Y
taking angle C let interior angle be Z
Again, In angle A
the sum of interior angle and exterior angle is 180 degree being staright line
Or, y+(x+5)=180
or,x+y=180-5
or, x+y=175
or,y=175-x --------eqn 1
In angle C
the sum of interior angle and exterior angle is 180 degree being staright line
or, x+z=180
or, z=180-x ----------eqn2
Again, In triangle ABC
total sum of all angle of triangle is 180 degree.
Angle A+ Angle B + AngleC=180
Or, y+79+z=180 -------eqn3
putting the value of eqn-1 and eqn-2 in eqn-3
Or, 175-x+79+180-x=180
Or, 431-180= 2x
Or, 254÷2=x
hence X= 127 degree

Step-by-step explanation:
What does the pattern in the residual plot indicate about the type of model?
a. The pattern is random, indicating a good fit for a nonlinear model.
b. The pattern shows the points are far from the zero line, indication a good fit for a linear model.
c. The pattern shows the points are far from the zero line, indicating a good fit for a nonlinear model.
d. The pattern is not random, indicating a good fit for a nonlinear model.
e. The pattern is random, indicating that the model is unable to be determined.
Answer: c. The pattern shows the points are far from the zero line, indicating a good fit for a nonlinear model.
d. The pattern is not random, indicating a good fit for a nonlinear model.
Step-by-step explanation:
A residual plot is a graph that represents
residuals on the vertical axis independent variable on the horizontal axis.Two main kids of plot are there.
First plot gives a random pattern, indicates a good fit for a linear model.
Other plots are non- random, indicates a good fit for a non- linear model.
Two points are correct for any residual plots :
c. The pattern shows the points are far from the zero line( basically u-shaped), indicating a good fit for a nonlinear model.
d. The pattern is not random, indicating a good fit for a nonlinear model.

A jar contains chocolate chip cookies and Anzac
biscuits. If Jim makes a selection at random from the
jar, he has a probability of selecting an Anzac
biscuit. If there are 10 chocolate chip cookies, how
many Anzac biscuits are there?
Answer:
0.20
Step-by-step explanation:
there are 4 + 6 + 10 = 20 biscuits in the jar
probability of picking a chocolate chip biscuit = 4/20 = 1/5 = 0.20
Is -20 solution x/-10=2?
Answer:
Yes
Step-by-step explanation:
Multiply -10 on both sides so x=-20

Find the slope of a line through the given points.
(3-7), (5,5)
Answer:
11/2
Step-by-step explanation:
Answer: m = 6
Step-by-step explanation: Start by writing down the slope formula.
m = y₂ - y₁ / x₂ - x₁
We take the second y minus the first y over the second x minus the first x.
m = 5 - (-7) / 5 - 3
m = 12 / 2
m = 6
So the slope of our line is 6.
