Answer:
B. {x| -3 < x ≤ 2}
Step-by-step explanation:
The unshaded "O" on "-3" implies that -3 is not included. Which means -3 < x or x > -3.
The shaded "O" on "2" implies that 2 is included, therefore, x is either equal to 2 or less than 2 (x ≤ 2) since the line is towards our left side. This, we would have:
{x| -3 < x ≤ 2}

If money is invested for a short period of time, simple interest is paid using the following formula.
I = Prt
P is the money invested, or principal amount, r is the simple interest rate, and t is the time, in years, the money is invested.
Given P = $2,000, t = 2 years, and I = $280, what is the simple interest rate?
A. 7%
B. 0.7%
C. 8%
D. 0.07%
Answer:
A. 7%
Step-by-step explanation:
Given the following data;
Principal, P = $2,000
Time, T = 2 years
Simple Interest, I = $280
To find the simple interest rate, R?
Mathematically, simple interest is calculated using this formula;
[tex] S.I = \frac {PRT}{100} [/tex]
Where;
S.I is simple interest. P is the principal. R is the interest rate. T is the time.Substituting into the equation, we have;
[tex] 280 = \frac {2000*R*2}{100} [/tex]
Cross-multiplying, we have;
[tex] 280 * 100 = 4000*R[/tex]
[tex] 28000 = 4000R [/tex]
[tex] R = \frac {28000}{4000} [/tex]
Simple interest rate, R = 7%

A diver is on a diving board 12 meters above the water. He dives vertically from the board with initial velocity of 4.9 meter/sec. how high will the diver get above the water?
Answer:
13.225 m
Step-by-step explanation:
Given that :
Initial Velocity, u = 4.9m/s
Acceleration due to gravity, a = - 9.8 m/s² (downward)
Distance, S = - 12
According to the motion equation :
S = ut + 0.5at²
S = 4.9t + 0.5(-9.8)t²
S = 4.9t - 4.9t² - - - (1)
At the highest point, v = 0
v² = u + at
0 = 4.9 + - 9.8t
-9.8t = - 4.9
t = 4.9/9.8
t = 0.5s
Put t = 0.5 in (1) above
S = 4.9(0.5) - 4.9(0.5)²
S = 2.45 - 1.225
S = 1.225 m
Total height :
(12 + 1.225) m = 13.225 m

The yearbook club had a meeting. The meeting had 18 people, which is one-third of the club. How many people are in the club?
Answer:
54
Step-by-step explanation:
Number of people in the meeting= 18
Out of this number 1/3 are from the club
Therefore the total number of club members can be calculated as follows
= 1/3 × x= 18
x = 18 × 3
= 54
Hence the number of people in the club is 54
what is the perimeter of this tile 6in 2in
Answer:
16in
Step-by-step explanation:
Most tiles a quadrilaterals meaning they have four sides, if it is 6in by 2 in, that means tou multiply both by two since there are two of each side length.
6 times 2 is 12
2 times 2 is 4
4 + 12= 16
Answer:

At 186282 miles per second, how far does light travel in a year? Give your answer in miles, but use scientific notation, which expresses a number like 93400000 as 9.34 × 107 (which might appear on your calculator as 9.34 E7 instead). A year is approximately 365.25 days. pleaasseeeeee heeelelpepepel,
Answer:
Use dimensional analysis to answer each of the following questions. To find the distance light travels in a year for part a, convert sec to yr by using unit ratios with min, hr, and days in their denominators. Thus, a light year is approximately 5,874,589,152,000 mi
The number of miles that the light covers in a light year will be 5.89 × 10¹² miles.
What is speed?Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
At 186282 miles per second.
We know that in one light year, the number of seconds will be 31.536 × 10⁶.
Then the distance is given as,
186282 = d / (31.536 × 10⁶)
d = 31.536 × 10⁶ × 186282
d = 5.89 × 10¹² miles
The number of miles that the light covers in a light year will be 5.89 × 10¹² miles.
More about the speed link is given below.

The test scores on a 100-point test were recorded for 20 students:71 93 91 86 7573 86 82 76 5784 89 67 62 7277 68 65 75 84a. Can you reasonably assume that these test scores have been selected from a normal population? Use a stem and leaf plot to justify your answer.b. Calculate the mean and standard deviation of the scores.c. If these students can be considered a random sample from the population of all students, find a 95% confidence interval for the average test score in he population.
Answer: a. Yes
b. mean = 76.65
standard deviation = 10.04
c. 76.65 ± 4.4
Step-by-step explanation:
a. Stem and leaf Plot shows the frequencies with which classes of value occur. To create this plot, we divide the set of numbers into 2 columns: stem, the left column, which contains the tens digits; leaf, the right column, which contains the unit digits.
Normal distribution is a type of distribution: it's a bell-shaped, symmetrical, unimodal distribution.
A stem and leaf plot displays the main features of the distribution. If turned on its side, we can see the shape of the data.
The figure below shows the stem and leaf plot of the 100-point test score. As we can see, when turned, the plot resembles bell-shaped distribution. So, this test scores were selected from a normal population.
b. Mean is the average number of a data set. It is calculated as the sum of all the data divided by the quantity the sample has:
mean = [tex]\frac{\Sigma x}{n}[/tex]
For the 100-point test score:
mean = [tex]\frac{71+93+91+...+65+75+84}{20}[/tex]
mean = 76.65
Standard Deviation determines how much the data is dispersed from the mean. It is calculated as:
[tex]s=\sqrt{\frac{\Sigma (x-mean)^{2}}{n-1} }[/tex]
For the 100-point test score:
[tex]s=\sqrt{\frac{[(71-76.65)+(93-76.65)+...+(84-76.65)]^{2}}{20-1} }[/tex]
s = 10.04
The mean and standard deviation of the scores are 76.65 and 10.04, respectively.
c. Confidence Interval is a range of values we are confident the real mean lies.
The calculations for the confidence interval is
mean ± [tex]z\frac{s}{\sqrt{n} }[/tex]
where
z is the z-score for the 95% confidence interval, which is equal 1.96
Calculating interval
76.65 ± [tex]1.96.\frac{10.04}{\sqrt{20} }[/tex]
76.65 ± 4.4
The 95% confidence interval for the average test score in the population of students is between 72.25 and 81.05.
