Answer: angle 1 = 51, angle 2 = 18, angle 3 = 123, angle 4 = 39
Step-by-step explanation:
72+57=129 180-129= 51 degrees for 1
90-72= 18 degrees for 2
180-57= 123 degrees for 3
123+18=141 180-141= 39 degrees for angle 4

3 consecutive integers for 273
Answers
Answer:
90, 91 and 92
Step-by-step explanation:
Given
Consecutive integers = 273
Required
Find the integers
The question seem to be incomplete. However, I'll assume we're dealing with sum.
Let the smallest integer be y.
So,
y + y + 1 + y + 2 = 273
Collect like terms.
y + y + y = 273 - 2 - 1
3y = 270
Divide both sides by 3
y = 90
Hence, the integers are 90, 91 and 92

Step-by-step explanation:
Suppose a purchasing manager wants to determine the average cost of machined metal parts in the US. How many machined metal parts would they have to sample? The manager wants to be 90% confident with a margin of error of 6.74. Suppose that the costs of the metal parts ranges from 93 to 220. When entering the values into JMP, round the planning value for the standard deviation to four values after the decimal. Round final answer as you normally would.
Answers
Answer:
they will have to sample 60 machined metal parts
Step-by-step explanation:
Given that;
Margin of Error E = 6.74
at 90% Confidence Interval, z = 1.645 { from table }
Range R = maximum range - minimum range = 220 - 93 = 127
standard deviation σ = R / 4 = 127/4= 31.7500
How many machined metal parts would they have to sample n = ?
to get our sample size, we use the following formula
n = [ zσ / E ]²
we substitute in our values
n = [ 1.645 × 31.7500 / 6.74 ]²
n = [ 52.2287 / 6.74 ]²
n = [ 7.7490 ]²
n = 60.047 ≈ 60
Therefore, they will have to sample 60 machined metal parts
You can use the margin of error with the z value and standard deviation to get the result.
The number of metal machine parts would be 60.
Given that:The confidence level needed is 90%The margin of error is 6.74The cost of metal parts ranges from 93 to 200To find:The number of machined metal parts that have to be sampled.
Finding the range of the distribution:Range = Max. value - min. value = 220 - 93 = 127
Finding the standard deviation:The standard deviation is approximately the quarter of the range of the distribution.
Thus, [tex]\sigma = 127 \div 4 = 31.75[/tex]
For 90% confidence, the z value is 1.645 (from z tables)
Thus, from the formula for size of sample, we have:
[tex]n = (\dfrac{z\sigma}{E})^2 = (\dfrac{1.645 \times 31.75}{6.74})^2 = (7.749)^2 \approx 60[/tex]
The number of metal machine parts would be 60.

Answer:
a) $166.67
b) $150
c) 38.04%
Step-by-step explanation:
a) The selling price (s) is the sum of the wholesale price (w) and the markup (m).
s = w + m
We have ...
250 = w + 0.50×w
250/1.50 = w = 166 2/3 ≈ 166.67
The wholesale cost of the bike is $166.67.
__
b) The price of the bike after the discount is 100% -40% = 60% of the tagged price:
0.60 × $250 = $150 . . . . . the discounted price
(Aside: we note this is less than the wholesale price, so the store is taking a loss on the bike when it is discounted this much.)
__
c) The percentage change is found by ...
percent change = ((new value)/(old value) -1) × 100%
= (114/184 -1) × 100% = (0.619565 -1) × 100% ≈ -38.04%
The discount is about 38.04%.

Answers
Answer:
x=10.7, y=11300
Step-by-step explanation:
x%of 31 = 3.317
x/100×31=3.317
31x/100=3.317
31x= 3.317×100
x= 3.317 ×100/31
x =10.7
4407= 39% of y
4407= 39/100 × y
4407 =39y/100
4407×100=39y

The manager of a magazine wants to estimate the percent of magazine subscribers who approve of a new cover format. To gather data, the manager will select a random sample of subscribers. Which of the following is the most appropriate interval for the manager to use for such an estimate?
a) A two-sample z-interval for a difference between sample proportions
b) A two-sample z-interval for a difference between population proportions
c) A one-sample z-interval for a sample proportion
d) A one-sample z-interval for a population proportion
e) A one-sample z-interval for a difference between population proportions
Answers
Answer: d) A one-sample z-interval for a population proportion
Step-by-step explanation:
For the scenario described above, since only a single sample pool is required from a single population, then ; The one sample Z interval for a population proportion is required ;
The interval may be calculated using the relation :
Z = (p - p0) / √[(p0(1 - p0)) / n]
p = observed proportion ;
p0 = mean or hypothesized value
n = sample size
Answer:
A two-sample z -interval for a difference in population proportions
