Answer: The value of x is 29°, the measure of angle 1 is 123°, and the measure of angle 2 is 57°.
Step-by-step explanation:
A linear pair is the same as a straight line meaning that the sum of the two angles has to equal 180 degrees.
In this case, add both angles and set them to equal to 180 in order to solve for x.
(4x + 7) + (2x-1) = 180 Combine like terms on the left side.
(4x + 2x) + ( 7 - 1) = 180
6x + 6 = 180 Now subtract 6 from both sides
-6 -6
6x = 174 Divide both sides by 6
x = 29
Since x is 29 degrees we will input it into the expression for the angles and solve for the real value.
m ∠1 = 4(29) + 7
m ∠1 = 116 + 7
m ∠1 = 123
If the measure of angle 1 is 123 degrees then you can subtract that from 180 to find the measure of angle two or you can use the expression.
m ∠2 = 2(29) -1
m ∠2 = 58 - 1
m ∠2 = 57

.A rectangle is constructed with its base on the diameter of a semicircle with radius 16 and with its two other vertices on the semicircle. What are the dimensions of the rectangle with maximum area?
The rectangle with maximum area has base __ and height __.
To find the dimensions of the rectangle with maximum area, we need to consider the relationship between the rectangle and the semicircle.
Let's assume that the base of the rectangle is the diameter of the semicircle. Since the radius of the semicircle is given as 16, the diameter (and base of the rectangle) will be 2 * 16 = 32.
Now, we need to determine the height of the rectangle. Since the other two vertices of the rectangle lie on the semicircle, the height of the rectangle will be the distance from the center of the semicircle to the top edge of the rectangle.
The center of the semicircle is also the midpoint of the base of the rectangle, so the distance from the center to the top edge of the rectangle will be equal to the radius of the semicircle.
Therefore, the height of the rectangle will be 16.
Hence, the dimensions of the rectangle with maximum area are:
Base: 32
Height: 16

A store that sells skis buys them from a manufacturer at a wholesale price of $57. The store's markup rate is 40%.
a. What price does the store charge its customers for the skis?
b. What percent of the original price is the final price?
c. What is the percent increase from the original price to the final price?
a) The selling price of the skis is $79.80.
b) The final price is 140% of the original price.
c) The percent increase from the original price to the final price is 40%.
a) Calculation of selling price:
Markup rate is 40%
Original cost = $57
Selling price = (100% + Markup percentage) × Original cost
Selling price = (100% + 40%) × $57
Selling price = 1.4 × $57
Selling price = $79.80
b) Calculation of percentage of the original price that is the final price
Percentage of original price that is the final price = (Final price / Original price) × 100%
Percentage of original price that is the final price = ($79.80 / $57) × 100%
Percentage of original price that is the final price = 140%
c) Calculation of the percentage increase
Percentage increase = (Final value − Initial value) / Initial value × 100%
Percentage increase = ($79.80 − $57) / $57 × 100%
Percentage increase = $22.80 / $57 × 100%
Percentage increase = 40%
Therefore, The store charges $79.80 for the skis. The final price is 140% of the original price and the percent increase from the original price to the final price is 40%.

(2x+15) What is the measure, in degrees, of angle D ?
The measure of angle D is ∠D = 65°.
What are similar triangles?Two triangles are said to be similar if there corresponding sides are proportional and their corresponding angles are equal.
Given is that triangle ΔABC is similar to triangle ΔDEF.
We can write -
∠D + x + 90° = 180°
∠D = 90° - x
Since both the triangles are similar, we can write -
∠D = ∠A
{90° - x} = {2x + 15}°
3x = 75°
x = 25°
∠D = 90 - x = 65°
∠D = 65°
Therefore, the measure of angle D is ∠D = 65°.

A simple random sample of 15 year old boys from one city is obtained in their weights are listed below use a 0.01 significance level to test the claim the these sample ways come from a population with a mean equal to 148 pounds. Assume that the standard deviation of the weight of a 15-year-old boys in the city is known to be 16.1 pounds. Use the traditional method of testing hypotheses.
Answer:
\/\/\/
Step-by-step explanation:
What you are testing is a distribution of means, because you have a sample of eleven individuals (N=11), a population mean, and the population variance. Basically, the problem is asking: what is the likelihood that the sample mean (153.45 lbs) could have been obtained from a population where (M=149) if the null hypothesis is true?
p1: 15 year old boys with a mean weight of 153.45 lbs from City "Unknown".
p2: 15 year old boys with a mean weight of 149.00 lbs from the population.
H1: The sample of boys from City "Unknown" was not drawn from a population where the average weight of 15 year old boys = 149lbs.
H0: The sample of boys from City "Unknown" was drawn from a population where the average weight of 15 year old boys = 149lbs.
Mean = 149 [μM = μ = 149]
Variance = 16.2squared/11 = 262.44/11 = 23.86 [σM2 = σ2/N]
Standard Deviation = 4.88 [σM = √σM2 = √(σ2/N)]
Shape = normal
Using .01 level of significance for a two-tailed test, the cutoff sample score is +/- 2.575
Z = (M-µ) / σM = (153.45 - 149) / 4.88 = .91
.91 < 2.575
σM or the Standard Error of the Mean is 4.88 so...
for 99% confidence interval,
lower limit = 153.45 + (-2.575)(4.88) = 140.88
upper limit = 153.45 + (2.575)(4.88) = 166.02
the 99% confidence interval = 140.88 — 166.02 (lbs)
the population mean (µ=149.00) is included in the interval, which confirms results of Z test.
Conclusion: retain null, there is <.01 probability that the sample from City "Unknown" was drawn from a population where the mean weight is NOT = 149.00lbs.
a score of x = 70 on an exam with µ = 82 and σ = 8, or a score of x = 60 on an exam with µ = 72 and σ = 12?
A score of x = 60 on an exam with μ = 72 and σ = 12 is comparatively better than a score of x = 70 on an exam with μ = 82 and σ = 8.
To compare the two scores, we can convert them to z-scores, which tell us how many standard deviations a particular value is from the mean. The formula for z-score is:
z = (x - μ) / σ
where x is the value, μ is the mean, and σ is the standard deviation.
For the first score of x = 70 on an exam with μ = 82 and σ = 8, the z-score is:
z = (70 - 82) / 8 = -1.5
For the second score of x = 60 on an exam with μ = 72 and σ = 12, the z-score is:
z = (60 - 72) / 12 = -1.0
The z-score for the first score is lower than the z-score for the second score, which means that the first score is further below its mean than the second score is below its mean. Therefore, we can say that a score of x = 60 on an exam with μ = 72 and σ = 12 is comparatively better than a score of x = 70 on an exam with μ = 82 and σ = 8.

The two given rectangles are proportional to each other since they have a width-to-length ratio of 2 and the area ratio between them is equal to 9.
Two rectangles are proportional to each other when both have the same length-to-width ratio. The area ratio is defined by the following formula:
r' = (l' · h')/(l · h) (1)
Where:
l' - Length of the enlarged rectangle.
l - Length of the original rectangle.
h' - Length of the enlarged rectangle.
h - Length of the original rectangle.
Now we determine the length-to-width ratio of each rectangle:
Original rectangle
s = 4/2
s = 2
Enlarge rectangle
s' = 12/6
s' = 2
The two rectangles have the same length-to-width ratio.
The area ratio is:
r' = (12 · 6)/(4 · 2)

given that £1 = $1.62
how much is £650 in $
Answer:
$1053
Step-by-step explanation:
If we have that £1 = $1.62, then we can multiply both sides by 650 in order to get £650 on the left side of the equality. We must multiply the right side also by 650, and so we get £650=$1.62 * 650.
To do this multiplication, we can break 1.62 down simply into $1.00 +$0.6+$0.02
650*$1.00=$650, 650*$0.6=650*6/10=65*6=$390, and 650*$0.02=650*2/100=6.5*2=$13.
When we add these three products together, we get $650+$390+$13=$1053. And so, £650=$1053
Two variables are connected by the relation: P∝1/Q^2
Q is increased by 40%
To the nearest percent, describe the change in P
in percentage terms.
The change in P in percentage terms is 51% decrease.
How to illustrate the information?Since the two variables are connected by the relation, this will be illustrated as:
P=k/Q^2
where k is the proportionality constant.
Now, If Q is increased by 40%, i.e. the update Q' = Q + 0.4Q.
Now, we have
P1 = k/Q^2 and P2 = k/(Q+0.4Q)^2
P2/P1 = {k/(Q+0.4Q)^2}/{k/Q^2}
P2/P1 = 1/(1.4)^2
P2=0.51*P1
P2 = 0.5P1
Hence P reduces by 51%.

Assume a stick of length 1 is randomly broken into two portions. The smaller piece's estimated length is 0.25.
The random variable L (the length for the shorter stick) has a uniform distribution.
Thus the probability density function for L is as follows:
L = \(\frac{1}{0.5-0} = 2\)This means 2 for all length in the range 0 - 0.5
Now, we calculate the expected value for random variable L as seen on the attachment. Based on the calculation, 0.25 is the smaller piece's estimated length for the randomly broken stick.
