D) 107
Answers
Answer:
B) 132
Step-by-step explanation:
to find 1/4 of 528 we can multiply the values and get 528/4 = 132
also, you could multiply 528 by .25 because 1/4 is equal to .25 in decimal

How do you determine the value of the unknown exponent in the
equation 9,700 divided by 10 to the power of what equals 0.97?
Answers
Answer:
?=4
Step-by-step explanation:
First, we have to tell how we got from 9700 to 0.97. so we know that it is divided by 10^?. When you divide by 10, it is the same as moving the decimal point one space to the left. SO all you have to do is count how many times the decimal point got moved to get from 9700 to 0.97. This number is 4 so the question mark is 4 because 9700/10^4 will move the decimal place 4 to the right and give you 0.97.

Anas wants to build a one-sample z interval with 85% confidence to estimate what proportion of users will click an advertisement that appears on his website. He takes a random sample of 250 users and finds that 54 of them clicked the advertisement. Answer the following:
1. What critical value z start superscript, times, end superscript should Anas use to construct this confidence interval?
2. Provide the value of margin of error.
3. Provide the confidence interval with 85% of confidence.
4. What would happen if Anas managed to have 500 sample size?
Answers
Answer:
See below
Step-by-step explanation:
Check One Sample Z-Interval Conditions
Simple Random Sample? √
np≥10? √
n(1-p)≥10? √
One-Sample Z-Interval Information
Formula --> [tex]CI=\hat{p}\pm z^*\biggr(\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\biggr)[/tex]Sample Proportion --> [tex]\hat{p}=\frac{54}{250}=0.216[/tex]Critical Value --> [tex]z^*=1.4395[/tex] (for a 85% confidence level)Sample Size --> [tex]n=250[/tex]Margin of Error (MOE) --> [tex]\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex]Problem 1
As stated previously, Anas should use the critical value [tex]z^*=1.4395[/tex] to construct the 85% confidence interval
Problem 2
Given our formula for the margin of error (MOE), the value is [tex]MOE=\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}=\sqrt{\frac{0.216(1-0.216)}{250}}\approx0.026[/tex]
Problem 3
The 85% confidence interval would be [tex]CI=\hat{p}\pm z^*\biggr(\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\biggr)=CI=0.216\pm 1.4395(0.026)\appro=\{0.1786,0.2534\}[/tex], which means that we are 85% confident that the true proportion of people that clicked on the advertisement is between 0.1786 (~45 people) and 0.2534 (~63 people)
Problem 4
Increasing the sample size to [tex]n=500[/tex] is going to decrease the margin of error because it is a closer representation of the population, but, alas, requires more time, energy, and resources to observe.

give the points (4,-5) and (0,-2) on a line find the values of M and B.
y= mx+b
M= ?
B= ?
enter answers as integers and or as reduced fractions in the form A/B
Answers
Answer:
m = -3/4; b = -2
Step-by-step explanation:
y = mx + b
First, we use the coordinates of the points to find the slope, m.
m = (y2 - y1)/(x2 - x1) = (-2 - (-5))/(0 - 4) = (-2 + 5)/(-4) = -3/4
The slope, m = -3/4.
Now we use the slope and the coordinates of one point in the equation y = mx + b to find b.
y = mx + b
y = (-3/4)x + b
Let's use point (0, -2).
-2 = (-3/4)(0) + b
b = -2
Answer: m = -3/4; b = -2

Which choice shows (50 + 30) + 40 correctly rewritten using the associative property and then correctly simplified?
Answers
Answer:
(80)+40=120
Step-by-step explanation:
(50+30)+40
120
The required simplified value is 120.
Given that,
Top simplify the expression following the associative property.
(50 + 30) + 40.
In mathematics, it deals with numbers of operations according to the statements. There are ,four major arithmetic operators, addition, subtraction, multiplication and division,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
= (50 + 30) + 40
Simplification, using associative property, in parenthesis 50 + 30 become 80.
= 80 + 40
Again using associative property, 80 + 40 become 120
= 120
Thus, the reequired simplified value is 120.

Answer:
x = -2.25
Step-by-step explanation:
Answer:
x = -2.25
Step-by-step explanation:
Add 15 to both sides of the equation
-6x - 15 = -1.5
-6x-15+15=-1.5+15
Simplify
-6x = 13.5
Divide both sides of the equation by the same term
-6x/6 = 13.5/6
Simplify
x = -2.25

How do i write this equation from ordered pairs?? Pls help
Answers
Answer:
y = -x + 3
Step-by-step explanation:
First find the slope (rise over run):
[tex](\frac{5-1}{-2-2}) = \frac{4}{-4} = -1[/tex]
Since the slope is -1, use one of the given coordinates to write an equation in point-slope form:
y - 5 = -1(x + 2)
or optionally in slope-intercept form:
y = -x + 3
Answer:
equation : y = -x + 3
Step-by-step explanation:
coordinates given: (-2,5) and (2, 1)slope = ( y2-y1 ) / ( x2-x1 )
= ( 1 - 5 ) / ( 2 --2)
= -4 / 4
= -1
Now find equation using: y - y1 = m ( x - x1 )
: y - 1 = -1 ( x - 2 )
: y = -x +2 +1
: y = -x + 3
