The photo has the full solution
The number, when A two-digit positive number is such that the one's digit is 2.5 times as much as the ten's digit, is 25.
What is the equation?In other terms, an equation is a mathematical statement stating that "this is equivalent to that." It appears to be a mathematical expression on the left, an equal sign in the center, and a mathematical expression on the right.
Given:
A two-digit positive number is such that the one's digit is 2.5 times as much as the ten's digit,
Write the equations of the statement as shown below,
Assume the one's digit is x and the ten's digit is y then,
x = 2.5y
(10y + x) - (10x + y) = 27
Solve the above equation and find the value of x and y,
10y + x - 10x - y = 27
-9x + 9y = 27
-x + y = 3
-2.5y + y = 3 (Plug value of x)
-1.5y = 3
y = 2
x = 2.5 × 2
x = 5
Number = 2 × 10 + 5 = 25
Thus, the number is 25.

Average rate change to the nearest hundredth can be which answer ?
Answers
Answer:
0.47
Step-by-step explanation:
f(x) = (x - 2)^(1/3)
average rate of change from x = -2 to x = 4 is [f(4) - f(-2)]/[4 - (-2)]
f(-2) = (-4)^(1/3) = -1.587401
f(4) = 2^(1/3) = 1.25992
[f(4) - f(-2)]/[4 - (-2)] = [1.25992 - (-1.587401)]/[4 - (-2)] = 0.47

In this composite function, (f◦g)(x) where f(x)=(X-3) and g(x)=X^2 what is (f◦g)(x) when x=1?
Answers
Answer:
When x = 1, (f◦g)(x) is -2.
Step-by-step explanation:
Composite function:
The composite function of f and g is given by:
[tex](f \circ g)(x) = f(g(x))[/tex]
In this question:
[tex]f(x) = x - 3, g(x) = x^2[/tex]
Composite function:
The composite function is:
[tex]f(g(x)) = f(x^2) = x^2 - 3[/tex]
At x = 1
[tex](f \circ g)(1) = 1^2 - 3 = 1 - 3 = -2[/tex]
So
When x = 1, (f◦g)(x) is -2.

Which linear function is increasing at a greater
rate? Explain your reasoning.
Linear Function 1 has an x-intercept of (4, 0) and
a y-intercept at (0, 22)
Linear function 2 includes the points in the table
below
Answers
Answer:
Linear function 2
Step-by-step explanation:
If Linear function 1 has an x-intercept of 4,0 and a y-intercept of 0,22
It's a negative equation, Its not increasing Its decreasing.
So it must be Linear function 2
the second function
step-by-step explanation:
“increasing at a greater rate” is the slope
Function 1 has points at (4, 0) (0, 22)
to find the slope it would be
m = y2 - y1 / x2 - x1
m = 22 - 0 / 0 - 4
m = 22 / -4
m = -5.5
Function 2 we can take any two points from the table
I’m going to take (1, 0) and (3, 1)
m = 3 - 1 / 0 - 1
m = -2 / -1
m = 2 / 1
m = 2
because function 1 is negative function 2 would be increasing at a greater rate.

O The margin of error is multiplied by 2.
Answers
Answer:
The margin of error is multiplied by 4.
Step-by-step explanation:
Margin of error is:
[tex]M = \frac{zs}{\sqrt{n}}[/tex]
In which z is related to the confidence level, s is elated to the standard deviation and n is the sample size.
From this, we have that the standard deviation is inversely proportional to the square root of the sample size.
If you cut the sample size in half:
The margin of error is inversely proportional to the square root of the sample size, so if you cut the sample size by [tex]\frac{1}{2}[/tex], the margin of error will be multiplied by [tex]2^2 = 4[/tex]
So
The margin of error is multiplied by 4.
