Answer:
The minimum score required for admission to the nearest whole number = 557
Step-by-step explanation:
We solve this using z score formula.
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Top 30% of the candidates is a ranking that is equivalent to = 100 - 30% = 70th percentile.
The z score of 70th percentile = 0.524
Mean = 497
Standard deviation of 114.
Minimum score = raw score = ???
Hence:
0.524 = x - 497/114
Cross Multiply
0.524 × 114 = x - 497
59.736 = x - 497
x = 59.736 + 497
x = 556.736
The minimum score required for admission to the nearest whole number = 557

A set of data has a mean of 58 and only one outlier of 92. Which statement about this data set must be true?
The range is 34.
The range is 34.
The mode is equal to the mean.
The mode is equal to the mean.
The mean is greater than the median.
The mean is greater than the median.
The distribution curve is skewed to the right.
Answer:
The correct option is;
The distribution curve is skewed to the right
Step-by-step explanation:
The given parameters are;
The mean = 58
The outlier = 92
Given that the outlier, P, can be found from the following formula, we have;
P > Q₃ + 1.5·IQR = (Q₃ + 1.5 (Q₃ - Q₁)
92 > (Q₃ + 1.5 (Q₃ - Q₁)
Given that mean = 58
Therefore, the IQR, and Q₃ are relatively small compared to the outlier, and the data is skewed, with the more smaller numbers than there are large numbers which makes the distribution curve to be skewed to the right.

An airplane is flying at an altitude of 2.7 miles and is 8.3 miles from the runway. Find the angle of depression that the airplane must make to land safely.
Answer:
-8.72811548... i think
Step-by-step explanation:
a² + b² = c²
8.3² + 2.7² = c²
68.89 + 7.29 = c²
76.18 = c²
√76.18, -√76.18 = c
c = 8.72811548…, −8.72811548…
I think because it's depression, it's -8.72811548...

Elena finds that the area of a house on a scale drawing is 25 square inches. The actual area of the house is 2,025 square feet. What is the scale of the drawing?
Answer:
81 sq. inches
Step-by-step explanation:
Since they are asking for the scale of her drawing,
you have to divide the actual area of the house
by the area of the house on a scale drawing.
You only divide if they ask for the scale of the
drawing.
also
You only multiply if they ask for the scale of the
actual model.
Which point represents the unit rate?
Answer:

Costumers can pick their own blueberries at Blueberry Hill. They pay $5 to enter the patch and $4 per pound for the blueberries they pick. Write an equation to model the total cost, y, fo x pounds of blueberries.
Answer:
c. y = 4x + 5
Step-by-step explanation:
you are paying a one time fee of $5 to get in and $4per x number of pounds.
Answer:
B
Step-by-step explanation:
Firstly you pay 4 dollars to enter BH
If x is the number of pounds of blueberries, then the amount spent is going to be 5x as each pound is 5 dollars. Then you add the costs together, so it would be 5x+4 which is B

Cindy runs 2 kilometers every morning. She takes 2 minutes for the first 250 meters, 4 minutes for the next 1,000 meters, 1 minute for the next 350 meters, and 3 minutes for the rest.
Cindy’s average speed for the entire run is ________
meters per minute. One kilometer is the same as 1,000 meters.
Answer:
286.1
Step-by-step explanation:
2 km = 2000 m
2 min = 250 m -> 125 m in 1 min
4 min = 1000 m -> 250 m in 1 min
1 min = 350 m -> 350 m in 1 min
3 min = 400 m (the rest) -> 133.33 m in 1 min
To get the average you add up all 3 and divide by 3
So: 125 + 250 + 350 + 133.33 = 858.33
858.33/3 = 286.11
So rounded its 286.1

Bill cut out 6 squares and 8 circles . He divided the cutouts into groups so that the same number of squares and circles were in each group. What is the greatest number of groups he could have made?
Answer:
2 groups
Step-by-step explanation
To find out how many groups can be made for 6 circles and 8 squares, start by finding what you can divide by both numbers.
6 can be divided by: 8 can be divided by:
1 1
2 2
3 4
6 8
The greatest number that they both have in common is 2. There would be 3 circles and 4 squares if Bill divided into 2 groups.
I hope this helped. Let me know if you still have any questions!
What is 8x8x8x8x3x3 in exponential form?
Step-by-step explanation:
[tex]8 ^{4} \times 3 {}^{2} [/tex]
Count how many of the same number, since you have four 8's the exponent will be
[tex]8 {}^{4} [/tex]
same applies for 3
Answer: [tex]8^4 \times 3^2[/tex]
On a keyboard, you can type 8^4*3^2 to indicate the same thing.
===========================================================
Explanation:
There are four copies of 8 being multiplied. Writing [tex]8^4[/tex] is a shorthand way of saying [tex]8 \times 8 \times 8 \times 8[/tex]. The exponent tells us how many copies of the base to multiply out.
Similarly, we have two copies of 3 which means [tex]3 \times 3 = 3^2[/tex]

is not the y-intercept?
Edge 2020
Answer:
point slope form
Step-by-step explanation:
hi! we can use point slope form:
y-y1=m(x-x1)
where m is the slope, x1 is the x-coordinate of the given point, and y1 is the y-coordinate of the given point.
example:
slope is 4
ordered pair is (2,3)
y-3=4(x-2)
y-3=4x-8
y=4x-5
