Step-by-step explanation:
Answer:
-2 + 10=8
Adding a negative to a positive is just like subracting whole numbers so
10-2=8
so 2 would be your answer

Mira uses the mapping rule to find the coordinate of a point that had been rotated 90° clockwise about the origin. Examine Mira’s solution to determine which step has an error.
M(–5, –6) is rotated 90° clockwise.
Step 1. Use the rule (x, y)g(y, –x).
Step 2. Switch x and y coordinates:
(–6, –5)
Step 3. Multiply the new x-coordinate by –1:
((–1)–6, –5)
Step 4. Simplify:
(6, –5)
Mira made an error in Step
Answer:
3
Step-by-step explanation:
Answer: You multiply the old x coordinate by negative 1, so the error is at step 3.
It should give (-6, (-1)-5).

A rectangular rug has an area of 84 square feet. If the length is 8 feet more than the width, find the dimensions of the rug.
Answer:
w=6
l=14
Step-by-step explanation:
Area of rectangle = l*w
So:
[tex]w*(w+8)=84[/tex]
Then, just find w, and w+8.
[tex]w^2+8w=84\\w^2+8w-84=0\\(w-6)(w+14)=0\\w-6=0, w=6\\w+14=0, w=-14[/tex]
Length cannot be negative, so the width is 6.
Length = width + 8 = 6+8=14

Answer:
8 divided by 1/3 is 24 because you are dividing a fraction so it is basically 8*3 (inverse operations). As for 2/3 it does not have one as a numerator so it automatically is less that 1/3

A recent study in a small city stated that the average age of robbery victims was 63.5 years. A random sample of 20 recent victims had a mean of 63.7 years and a standard deviation of 1.9 years. At = 0.05, is the average age higher than originally believed?
Answer:
The p-value of the test is of 0.3219 > 0.05, which means that at [tex]\alpha = 0.05[/tex], the average age is not higher than originally believed.
Step-by-step explanation:
A recent study in a small city stated that the average age of robbery victims was 63.5 years. Test if the average age higher than originally believed.
At the null hypothesis, we test that the mean is the believed mean age of 63.5 years, that is:
[tex]H_0: \mu = 63.5[/tex]
At the alternate hypothesis, we test if this mean is higher, that is:
[tex]H_1: \mu > 63.5[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
63.5 is tested at the null hypothesis:
This means that [tex]\mu = 63.5[/tex]
A random sample of 20 recent victims had a mean of 63.7 years and a standard deviation of 1.9 years.
This means that [tex]n = 20, X = 63.7, s = 1.9[/tex]
Test statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{63.7 - 63.5}{\frac{1.9}{\sqrt{20}}}[/tex]
[tex]t = 0.47[/tex]
P-value of the test and decision:
The p-value of the test is the probability of finding a sample mean above 63.7, which is a right-tailed test, with t = 0.47 and 20 - 1 = 19 degrees of freedom.
With the help of a calculator, this probability is of 0.3219.
The p-value of the test is of 0.3219 > 0.05, which means that at [tex]\alpha = 0.05[/tex], the average age is not higher than originally believed.

Answer:
7
Step-by-step explanation:
Given :
A right angled triangle with one angle 64° and side 15 .And we need to find the value of x to the nearest tenth. So the correct approach will be ,
[tex]:\implies[/tex] tan 64° = p/b
[tex]:\implies[/tex] tan 64° = 15/x
[tex]:\implies[/tex] x = 15 / tan64°
[tex]:\implies[/tex] x ≈ 7
He commited a mistake in 2nd step. He should have written 15/ tan64° .Hence the correct answer is 7 .
Use the graph to determine

b) Range: y≤-2
c) x-intercepts: None
d) y-intercepts: (0,-2)
e) f(4)= -4
Step-by-step explanation:
If this helps please mark as brainliest
(a) domain is [0,∞)
(b) Range is [-2,-∞)
(c) X intercept is none
(D) Y intercept is (0,-2)
(E) f(4)=-4
Given :
Use the given graph to determine the domain , range etc.
Explanation :
Domain is the set of x values on the graph
The graph starts at x=0 and goes on .
So domain is [0,∞)
Range is the set of y values on the graph
The graph starts at y=-2 and it goes down
Range is [-2,-∞)
X intercepts are the points where the graph crosses or touches x axis
The graph does not cross the x axis
X intercept is none
Y intercepts are the points where the graph crosses or touches y axis
The graph touches y axis at -2
Y intercept is (0,-2)
To find out f(4) we look at the y value when x=4
f(4)=-4

Step-by-step explanation:
For each of the following research scenarios, decide whether the design uses a related sample. If the design uses a related sample, identify whether it uses matched subjects or repeated measures. (Note: Researchers can match subjects by matching particular characteristics, or, in some cases, matched subjects are naturally paired, such as siblings or married couples).
A researcher is interested in whether people eat more or less when they are in a hurry. The researcher collects a random sample of 80 adults and invites them to eat two (identical) free meals one month apart. For one of the meals, no time restriction is placed on the meal. For the other meal, participants are told when their meal is served that they have only 10 minutes until another group is due to sit down. Half of the participants eat their hurried meal first; the other half eat it second. The researcher compares the amount eaten at each sitting. The design described_____.
John Cacioppo was interested in possible mechanisms by which loneliness may have deleterious effects on health. He compared the sleep quality of a random sample of lonely people to the sleep quality of a random sample of nonlonely people. The design described____.
a. uses a related sample (repeated measures).
b. uses a related sample (matched subjects).
c. does not use a related sample.
Answer:
A.) uses a related sample (repeated measures).
B.) does not use a related sample.
Step-by-step explanation:
The first scenario uses a related sample whereby same subjects were used to over the course of each related experiment (comparing if people eat more or less when in a hurry). After the completion of both experiment, we'll have two different reading for each subject which a b further be used to compare the difference in consumption when in a hurry and when not.
The second scenario here fails to employ a related sample design as the the subjects used have contrasting characteristics, a group consisting of lonely people and another consisting of those who aren't lonely.

semi-circle because the measure of a whole circle is 360°.
Arc :
The arc of a circle consists of two points on the circle and all of the points on the circle that lie between those two points. It's like a segment that was wrapped partway around a circle. An arc is measured not by its length (although it can be, of course) but most often by the measure of the angle whose vertex is the center of the circle and whose rays intercept the endpoints of the arc. Hence an arc can be anywhere from 0 to 360 degrees.

A tortoise crawling at a rate of 0.1 mi/h passes a resting hare. The hare wants to rest another 30 min
before chasing the tortoise at the rate of 5 mi/h. How many feet must the hare run to catch the tortoise?
Answer:
The rabbit will run 264feet to get to the tortoise
Step-by-step explanation:
To solve this problem perfectly, we need to take note of the units and conversions involved.
The speed of the tortoise is 0.1 mi/hr
The speed of the hare is 5mi/hr
If the hare rests for another 30 minutes before he starts running the race, We are to get the distance covered by the tortoise under this 30 minutes.
The tortoise runs 0.1 miles in 1 hour
The tortoise will run x miles in 0.5 hours.
x = 0.5 X 0.1 = 0.05 miles.
Therefore, the distance covered by the Tortoise within 30 minutes is 0.05 miles.
The hare will have to run for 0.05 miles before he can catch up to the tortoise.
It is now unit conversion comes into play. We are converting the 0.05 miles to feet so we can get our final answer.
The answer in feet is 264 feet.
Therefore, the rabbit will run 264feet to get to the tortoise
