What are the values of the new mean and standard
deviation of the students' reading times?
A group of 19 students registered for a speed-reading
class at a local community college. On the first day of
class, students were timed as they read a passage
from a novel. The mean time of all the students was
189 minutes with a standard deviation of 21 minutes.
Six months later, the students were timed again as they
read a passage of similar length and readability level.
Each student in the course lost exactly 10 minutes on
their reading times.
O mean = 179 minutes and standard deviation = 11
minutes
O mean = 179 minutes and standard deviation = 21
minutes
O mean = 179 minutes and standard deviation = 31
minutes
O mean = 189 minutes and standard deviation = 11
minutes
O mean = 189 minutes and standard deviation = 21
minutes
Answer:
Second answer, O mean = 179 and standard deviation = 21 minutes.
Step-by-step explanation:
The mean will decrease but the standard deviation(average difference) between the data points will remain the same.

First, angle ACB will be equal to 90° as it is the angle that lies on the same arc as the diameter. From there you can find angle y with angle A+ angle B+ Angle C=180°
then you can find the angle complementary to x with the same formula then you can subtract that angle with 90° to get x.

It is estimated that 7 out
of 10 people invited to a
wedding will attend. If Mark
and Katie invite 120 people,
how many can they expect to
not attend?
Answer:
They can expect that 36 people will not attend.
Step-by-step explanation:
We are trying to figure out how many people didn't attend, so that would be 10 invites - 7 attendees = 3 bailers, so 3/10 people won't attend.
Now, you need to multiply that ratio to become 120 people:
3/10 --> x/120
In order to change that fraction, you must figure out what 120/10 is:
120/10 = 12
This means that the denominator was multiplied by 12, so the numerator must also be multiplied by 12 to get x:
3/10 --> (3*12)/120
--> 36/120
36 out of 120 people can be expected not to attend.

In-line skaters A study of injuries to in-line skaters used data from the National Electronic Injury Surveillance System, which collects data from a random sample of hospital emergency rooms. The researchers interviewed 161 people who came to emergency rooms with injuries from in-line skating. Wrist injuries (mostly fractures) were the most common.
The interviews found that 53 people were wearing wrist guards and 6 of these had wrist injuries. Of the 108 who did not wear wrist guards, 45 had wrist injuries. Why should we not use the large-sample confidence interval for these data?
a. Because 161 people are not enough for using the large-sample confidence interval.
b. Because the difference in sizes of the two groups is too large.
c. Because there are only 6 skaters in one group having wrist injuries.
d. Because the sample error is two large.
Using the Central Limit Theorem, it is found the correct option regarding why the large-sample confidence interval for these data.
c. Because there are only 6 skaters in one group having wrist injuries.
What does the Central Limit Theorem state?It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex], that is, as long as there are at least 10 successes and at least 10 failures in the sample.
In this problem, for the sample of people wearing wrist guards, only 6 had injuries, hence the large-sample confidence interval should not be used and option C is correct.

A real estate agent believes that the values of houses in the neighborhood she works in have increased from last year. To test this claim, she selects random houses in this neighborhood and compares their estimated market values in the current year to their estimated market values in the previous year. Suppose that data were collected for a random sample of 8 houses, where each difference is calculated by subtracting the market value of the previous year from the market value of the current year. Assume that the values are normally distributed. What type of test is this hypothesis test?
Answer:
alternative hypothesis test
Explanation:
Remember, the alternative hypothesis test usually suggests that there is a chance of variation (difference) in the data observed.
Hence, since we are told the "real estate agent believes that the values of houses in the neighborhood she works in have increased (the chance of variation) from last year," and that "each difference is calculated by subtracting the market value of the previous year from the market value of the current year," we can reach the conclusion that this is an example of an alternative hypothesis test.

2. The table shows the mass of fibres in 100 grams of each food item below. Food Mass of fibre (grams per 100 grams) Beans Bread Soup Cornflakes Pasta 3.6 2.4 0.7 2.5 3.0 i. A small tin of beans contains 200 grams. If you are going to eat two-thirds (2/3) of this small tin of beans, how much fibres will you consume? Show your calculations. (2 marks)
Given that the amount of fiber in 100 grams of beans is 3.6 grams the amount of fiber consumed from [tex]\mathbf{\frac{2}{3}}[/tex] of the small tin is 4.8 grams.
How can the amount of fiber consumed be calculated?From the given table, we have;
Mass of fiber in 100 g of beans = 3.6 grams
Mass of beans in the small tin = 200 grams
The quantity of the beans eaten = [tex]\frac{2}{3}[/tex] of the small tin
Required:
The amount of fiber to consumed from eating [tex]\frac{2}{3}[/tex] of the small tin
Solution;
[tex]Amount \ of \ fiber \ consumed = 200 \, g \times \dfrac{3.6 \, g}{100 \, g} \times \dfrac{2}{3} = \mathbf{4.8 \, g}[/tex]
Therefore;
The amount of fiber consumed by eating [tex]\frac{2}{3}[/tex] of the small tin = 4.8 grams

Write an equation of the line passing through each of the following pairs of points.
(5, 7), (−8, −4)
Answer:
y= 11/13x + 36/13
Step-by-step explanation:
y=mx+b
y2 -y1 -4-7 = -11
x1-x2 -8-5= -13
slope is 11/13
Answer:
y = [tex]\frac{11}{13}[/tex] x + [tex]\frac{36}{13}[/tex]
Step-by-step explanation:
First, find the slope of the line passing through the points
Then find the y-intercept of the line
Then construct the formula
1. find the slope
remember the formula
[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex] is used to find the slope
now plug in the given points
(5, 7)
(-8, -4)
[tex]x_{1} = 5\\y_{1} = 7\\x_{2} = -8 \\y_{2} = -4[/tex]
[tex]\frac{(-4) - (7)}{(-8) - (5)}[/tex]
simplify and solve
= [tex]\frac{-11}{-13}[/tex]
= [tex]\frac{11}{13}[/tex]
2. find the y-intercept
remember the base formula for a line
y= mx + b
where m is the slope and b is the y-intercept
we know the slope, so now plug in one of the given coordinates for a point on the line and slove to find the y-intercept
y = mx + b
y = [tex]\frac{11}{13}[/tex]x + b
use the first set of given coordinates for a point on this line: (5, 7)
7 = [tex]\frac{11}{13}[/tex] * 5 + b
solve by inverse operations and simplifying
7 = [tex]\frac{55}{13}[/tex] + b
[tex]\frac{36}{13}[/tex] = b
3. construct the formula
now we know the slope and the y-intercept, all we have to do now is substitute it into the base formula for a line:
y = mx + b
where m is the slope and B is the y-intercept
we found that
m = [tex]\frac{11}{13}[/tex]
and
b = [tex]\frac{36}{13}[/tex]
so that means the equation is
y = [tex]\frac{11}{13}[/tex] * x + [tex]\frac{36}{13}[/tex]

A loan company charges $80 interest for a three-month loan of $550. Find the annual interest rate (APR) they are charging.
Answer:
Step-by-step explanation:
using the simple interst formula;
SI = Principal * Rtae * Time/100
Given
Principal = $550
SI = $80
Time = 3 month = 3/12 years
Required
Annual interest rate
Substitute
80 = 550 * R * 3/12*100
80 = 1650R/1200
96000 = 1650R
R = 1650/96000
R = 0.017
Rate = 0.017 * 100 = 1.7%

3x + 2 = 38
Answer:
3x=38-2
3x=36
3x÷3=36÷3
x=12
Step-by-step explanation:
You start by grouping the like terms on one side, 2 is a constant number so you will group it with the constant 38. When you swap it to the other side of the equal sign, you change its sign. After you will divide both sides of the equation by the coefficient of x which is 3,in order to get the value of x.

How to solve 0=X+1/x-2
Answer:
x = -1
Step-by-step explanation:
[tex]0= \frac{x+1}{x-2}\\[/tex]
Variable x cannot be equal to 2 since division by zero is not defined. Multiply both sides of the equation by x−2.
0 = x + 1
Swap sides so that all variable terms are on the left hand side.
x + 1 = 0
Subtract 1 from both sides. Anything subtracted from zero gives its negation.
x = -1
