What is the slope of a line that goes through the points (10, -2) and (5,-5)? m =
Y1-Y2
11-12
Answer:
m = 3/5
Step-by-step explanation:
use the formula so m = -5 - -2 / 5 - 10 , so m = -5+2 / -5
m = -3/-5 so m = 3/5

The applicable rules of logarithms are ...
log(ab/c) = log(a) +log(b) -log(c)
log(a^b) = b·log(a)

Researchers were investigating whether there is a significant difference between two medications, R and S, designed to reduce fleas found on cats. From a sample of 300 cat owners, the researchers randomly assigned 150 cat owners to use medication R on their cats and the remaining cat owners to use medication S. For the cats using medication R, 88 percent had no fleas. For the cats using medication S, 90 percent had no fleas. Which of the following is the most appropriate method for analyzing the results?
A two-sample z -test for a difference in population proportions
A two-sample z-test for a difference in sample proportions
A one-sample z-test for a sample proportion
A one-sample z-test for a population proportion
A one-sample z-test for a difference in sample proportions
Answer:
A) A two-sample z -test for a difference in population proportions
Step-by-step explanation:
To determine whether a difference in proportions is significant, the two-sample z-test for a difference in population proportions is the most appropriate method for the analysis.
The most appropriate method for analyzing the results is A. A two-sample z-test for a difference in population proportions.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter.
In this scenario, we have two different treatments (medication R and S) applied to two separate samples (150 cat owners each) and we want to determine if there is a significant difference in the proportion of cats with no fleas between the two groups.
This is a classic scenario for a two-sample z-test for a difference in population proportions, which tests the hypothesis that the difference in proportions between two independent populations is equal to zero.
Thus, a two-sample z-test for a difference in population proportions.
Hence, the correct answer would be option (A)

Joseph plots the speed of his car and time on a scatter plot. The equation for the line of best fit on his scatter plot is y = -15x + 60, where x is the time in hours and y is the speed in miles/hour. Which statement describes the situation correctly?
A.
The initial speed is 60 miles/hour, and his speed decreases by 15 miles/hour every hour.
B.
The initial speed is 60 miles/hour, and his speed increases by 15 miles/hour every hour.
C.
The initial speed is 0 miles/hour, and his speed increases by 15 miles/hour every hour.
D.
The initial speed is 5 miles/hour, and his speed increases by 30 miles/hour every hour.
Answer:
A
Step-by-step explanation:
His speed change is the slope or -15, decreases by 15 miles/hour
when he starts, his speed is 0*-15+60 = 60 miles/hour

Answer:
26.42139285
Step-by-step explanation:
26x26 + 4.7x4.7 = c2
676 + 22.9 =c2
698.09=c2
square root of 698.09=26.42139285

A local bakery sells cupcakes for $3.50 each. The fixed monthly cost totals $275 which includes rent, utilities, and wages. Each cupcake costs the bakery 0.90 to make.
Answer: 110 cupcakes
Step-by-step explanation:
Assuming this question is asking for the breakeven point, you can find that by using the formula:
= Fixed cost / Contribution margin
Contribution margin = Sales price - variable cost (amount to make one cupcake)
= 3.50 - 0.90
= $2.60
Breakeven point = 275 / 2.60
= 109.77
= 110 cupcakes

The maximum value of a data set consisting of 25
positive integers is 84. A new data set consisting of 26
positive integers is created by including 96 in the
original data set. Which of the following measures
must be 12 greater for the new data set than for the
original data set?
A) the mean
B)the median
C)the range
D)the standard deviation
The new data set's range must be greater than the original data set's range. which is the correct answer would be an option (C).
What is the range of the data?The range of the data is defined as the difference between the maximum value of data and the minimum value of the data.
Let m be the smallest value in the original data collection.
Given that the original data set's range = 84 -m
A new data set is made up of 26 positive integers and 96 from the existing data set.
As a result, the new data set's range is 96-m.
We can now determine the difference between two ranges by subtracting them :
⇒ (96 - m) - (84 - m)
⇒ 96 - m - 84 + m
⇒ 12
As a result, the new data set's range must be greater than the original data set's range.
Hence, the correct answer would be an option (C).
