Answer:
QR = 2
Step-by-step explanation:
The sum of ratio units is 4+5+2 = 11, corresponding to the total length OP +PQ +QR = OR. OR is also 11, so each ratio unit stands for 11/11 = 1 length unit.
The number of ratio units associated with QR is 2, so the length of QR is 2.

Which property is used in step 4?
Answer:
B. Transitive property
Step-by-step explanation:
Transitive property, just like in the case of transitive property of equality, which says that if m = n, and o = m, therefore, o = n.
This property is what is also applied in the given proof above.
Thus:
Since, <1 ≅ <5, and <3 ≅ <5, therefore,
<3 ≅ <5 by transitive property.
The answer is:
✅Transitive property

How do you do this question?
Answer: B) Demand will most likely be elastic
Place yourself in the shoes of the employer. To them, demand is them needing/wanting workers. Specifically we call this "labor demand". The supply is the potential or current worker providing the service and/or making the product.
If the price goes up, then this means the worker earns higher wages. This in turn causes labor demand to fall. So the employer will be less likely to hire more workers if the wages increase. It's similar to how if the price of an item goes up in a store, then less people are probably going to buy it.
Demand is elastic because a small change in price causes a large change in demand. The company is going to be sensitive to wage changes. The company sees that it is approaching the diminishing returns, so it is likely to scale back on labor to save costs. It's all about trying to minimize costs and maximize revenue. Often, revenues can't be changed very much since customers are themselves sensitive to price changes (assuming there are substitutes in the market), so the company will turn to trying to reduce costs as much as possible leading to maximum profit.

BRAINEST TO WHOEVER GIVES A REAL ANSWER Kim and Tegan train for the iron man on the weekend. They bike at a constant rate of miles per hour. The tables below show Kim and Tegan’s total (distance) for biking a given amount of time. Find the missing value in the chart. (highlighted yellow)
Answer: To fill in the yellow highlighted blank, the answer is 128.
Step-by-step explanation:
For every 4 hours, there is 64 miles. If you multiply 4 by 2, you get 8, so in order to get the amount of miles per 8 hours, you would have to multiply 64 by 2. 64 by 2 is 128.
Hope this helps!
Answer:
128
Step-by-step explanation:
We have to find the slope for Kim;
(2, 32)(4, 64)
[tex]Slope=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }=\frac{64-32}{4-2}=\frac{32}{2}=16[/tex]
y = 16x
y(8) = 16*8
y(8) = 128

Step-by-step explanation:
In Ms. Henrick's class, there are 10 boys and 12 girls. What is the ratio of boys to girls? Express your answer as a fraction in simplest form.
Answer:
the ratio is 10:12 and if you were to write it in a fraction you get 10/12 which can be simplified as 5/6
Work Shown:
x = number of boys
y = number of girls
In this case,
x = 10
y = 12
So we have the fraction x/y = 10/12
From here, we divide each part by the GCF 2
10/2 = 5
12/2 = 6
Therefore, the fraction 10/12 reduces to 5/6
A large jar contains a mixture of white and black beans. In a randomly chosen handful of 120 beans 40 were black. Create a 98% confidence interval for the proportion of black beans in the jar. Express your answer to the nearest percent.
Answer:
23%<x<43%
Step-by-step explanation:
The formula for calculating confidence interval is expressed;
Confidence Interval = p ± z√p(1-p)/n
n is the sample size
z is the z score at 98% confidence interval
n is the sample size = 120
z = 2.33
If in a randomly chosen handful of 120 beans 40 were black, then;
p = 40/120
p = 4/12
p = 0.33
CI = 0.33± 2.33√0.33(1-0.33)/120
CI = 0.33± [2.33√0.33(0.67)/120]
CI = 0.33± [2.33√0.2211/120]
CI = 0.33± [2.33(0.04292)]
CI = 0.33±0.100014
CI = (0.33-0.100014, 0.33+0.100014)
CI = (0.229, 0.430014)
CI = (22.9, 43.0014)
Hence 98% confidence interval for the proportion of black beans in the jar is 23%<x<43%.
