Answer:
width - 5cm
length - 10cm
Step-by-step explanation:
Let's define the variable w as the width of the rectangle. The length of the rectangle would be 2w as given by the problem. A form of the perimeter of a rectangle formula is:
P = 2(l + w)
Where P is the perimeter, l is the length, and w is the width. We substitute our length, width, and perimeter to get:
30 = 2(2w + w)
You can simplify to get:
30 = 2(3w)
and divide by 6 on both sides to isolate w:
w = 5cm - the width is 5 cm
The length is twice the width, and 2 x 5 is 10, so 10cm is the length.

A random sample of small business stock prices has a sample mean of x¯=$54.82 and sample standard deviation of s=$8.95. Use the Empirical Rule to estimate the percentage of small business stock prices that are more than $81.67. Round your answer to the nearest hundredth.
Answer:
The right solution is "0.15%".
Step-by-step explanation:
The given values are:
Mean,
[tex]\bar{x}=54.82[/tex] $
Standard deviation,
[tex]s = 8.95[/tex] $
[tex]P(X>81.67)[/tex]
Now,
= [tex]P(z>\frac{81.67-\bar{x}}{s} )[/tex]
On substituting the values, we get
= [tex]P(z>\frac{81.67-54.82}{8.95} )[/tex]
= [tex]P(z>\frac{26.85}{8.95})[/tex]
= [tex]P(z>3)[/tex]
By using the table, we get
= [tex]0.0015[/tex]
= [tex]0.15[/tex]%
22,19,16,13 what is the 37th term
Answer:
-86
Step-by-step explanation:
3x10=30
22-3=19-3=16-3=13
so if its tthe 37th term, lets do 30x3=90
now 13-90=-77
-77=34th term
now just -3 until 37
-80
-83
-86
the 37th term is -86
Last Friday, Jason purchased 12 packages of baseball cards. Each package contained 35 cards. If 1/7 of the cards featured pitchers, how many cards featured batters?
Answer: 360
Step-by-step explanation:
12 packages * 35 cards = 420 total cards.
1/7 of 420 = 420 * 1/7 = 60
if 60 cards were pitchers, then 420-60 = 360 cards were batters
if the length is 9 cm,breadth is 10 cm and volume of cuboid is 1800cm cube ,,find the height and total surface area of cuboid,
Answer:
the height is 20 cm.
tsa is 940 cm square
Step-by-step explanation:
volume of cuboid = l*b*h
1800 = 9*10*h
h= 20 cm
TSA = 2(L*B+ B*H + L*H)
= 2(9*10 + 10*20 + 9*20)
=940 cm square
The height of the cuboid will be 20 cm
The total surface area of cuboid will be 940 cm²
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The length of cuboid = 9 cm
The breadth of cuboid = 10 cm
And, The volume of cuboid = 1800 cm³
Now,
We know that;
Volume of cuboid = Length × Breadth × Height
⇒ 1800 = 9 × 10 × h
⇒ 1800 / 90 = h
⇒ h = 20 cm
And, The total surface area of cuboid = 2lw + 2lh + 2hw
Substitute all the values, we get;
⇒ The total surface area of cuboid = 2 (9 × 10 + 9 × 20 + 20 × 10)
= 2 (90 + 180 + 200)
= 2 × 470
= 940 cm²

Tommy the Dunker's performance on the basketball court is influenced by his state of mind: If he scores, he is twice as likely to score on the next shot as he is to miss, whereas if he misses a shot, he is six times as likely to miss the next shot as he is to score.
Required:
a. If Tommy has missed a shot, what is the probability that he will score two shots later?
b. In the long term, what percentage of shots are successful?
Answer:
Step-by-step explanation:
Probability of of winning next shot if he scores= 0.5
Probability of missing next shot if he misses = 1/6
a) Probability of scoring 2 shots later if he missed = (1-1/6)^2
=(5/6)^2
=25/36
b) % of successful shots= (1/2+5/6×(1/100))%
=4/3×1/100
=0.013%
Four hundred randomly selected working adults in a certain state, including those who worked at home, were asked the distance from their home to their workplace. The average distance was x-bar equal to 8.84 miles. Assume that the standard deviation of the population of all working adults in that state is 2.70 miles. Construct a 99% confidence interval for the mean distance from home to work for all residents of this state. Droble
Answer:
The 99% confidence interval for the mean distance from home to work for all residents of this state is between 8.49 and 9.19 miles.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.575\frac{2.7}{\sqrt{400}} = 0.35[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 8.84 - 0.35 = 8.49 miles.
The upper end of the interval is the sample mean added to M. So it is 8.84 + 0.35 = 9.19 miles.
The 99% confidence interval for the mean distance from home to work for all residents of this state is between 8.49 and 9.19 miles.

move two choices to the blanks to correctly complete the sentences.
Answer:
(A) There should have been 5 outcomes of HT
(B) The experimental probability is greater than the theoretical probability of HT.
Step-by-step explanation:
Given
[tex]S = \{HH,HT,TH,TT\}[/tex] -- Sample Space
[tex]n(S) = 4[/tex] --- Sample Size
Solving (a); theoretical outcome of HT in 20 tosses
First, calculate the theoretical probability of HT
[tex]P(HT) = \frac{n(HT)}{n(S)}[/tex]
[tex]P(HT) = \frac{1}{4}[/tex]
Multiply this by the number of tosses
[tex]P(HT) * n= \frac{1}{4} * 20[/tex]
[tex]P(HT) * n= 5[/tex]
Solving (b); experimental probability of HT
Here, we make use of the table
[tex]P(HT) = \frac{n(HT)}{n(S)}[/tex]
[tex]P(HT) = \frac{6}{20}[/tex]
[tex]P(HT) = 0.30[/tex] ---- Experimental Probability
In (a), the theoretical probability is:
[tex]P(HT) = \frac{1}{4}[/tex]
[tex]P(HT) = 0.25[/tex] ---- Experimental Probability
By comparison;
[tex]0.30 > 0.25[/tex]

Givin the equilateral triangle below find the value of y
Answer:
15°
Step-by-step explanation:
All angles in an equilateral triangle are equal.
Angle sum property of triangle = 180°

Answer:
1. 140 degrees
2. 40 degrees
3. 65 degrees
4. 75 degrees
5 115 degrees
Step-by-step explanation:
1. The inside angle adjacent to angle 1 is 40. We know this because a triangle's interior angles have to add up to 180, and the only number when added to 140 (60+80) to equal 180 is 40. That means that 1 has to be the other part to equal 180.
2. The same rule occurs as before. This time angle 1 is 140, and the line they share's angles have to equal 180, so 2 is 40.
3. The same rule occurs as before with the 105 outside the triangle. 40 + X + 75 = 180, which means that 3 is 65.
4. Using the 105 we can deduce that 105 + X = 180.
5. We use the 40, and angle 4 + X to equal 180. Then we use the X to find 5 to be 115.
Sorry if that is confusing. Your book will probably have better explanations that I will.
Which of the following is a major difference between a
hypothesis test with the t statistic formula and the test with a z‐
score?
a) You must know the population variance (or standard
deviation) for the z‐score but not for the t statistic.
b) You use the unit normal table to find critical values for
the z‐score test but not for the t test.
c) You must calculate the sample variance (or standard
deviation) for the t statistic but not for the z‐score.
d) All of the other options are major differences.
Answer:
What's the key difference between the t- and z-distributions? The standard normal or z-distribution assumes that you know the population standard deviation. The t-distribution is based on the sample standard deviation.
The major difference between a hypothesis test with the t statistic formula and the test with a z‐ score is,
⇒ You must know the population variance (or standard deviation) for the z‐score but not for the t statistic.
What is Standard deviation?Standard deviation is the measure of dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
We have to given that;
To find the major difference between a hypothesis test with the t statistic formula and the test with a z‐ score.
Now, We know that;
The major difference between a hypothesis test with the t statistic formula and the test with a z‐ score is the population variance (or standard deviation) for the z‐score but not for the t statistic.
Thus, The major difference between a hypothesis test with the t statistic formula and the test with a z‐ score is,
⇒ You must know the population variance (or standard deviation) for the z‐score but not for the t statistic.
