Explanation:
There are 16 ways to pick the first place winner, 15 for second place, and 14 for third place. Each time we count down by 1 because no single person can be in two (or more) places at once.
Overall, this leads to 16*15*14 = 3360 different permutations
An article included a summary of findings regarding the use of SAT I scores, SAT II scores, and high school grade point average (GPA) to predict first-year college GPA. The article states that "among these, SAT II scores are the best predictor, explaining 17 percent of the variance in first-year college grades. GPA was second at 15.6 percent, and SAT I was last at 13.3 percent." If the data from this study were used to fit a least squares line with y = first-year college GPA and x = high school GPA, what would the value of r2 have been?
Answer:
0.156
Step-by-step explanation:
Given that :
% of Explained variance by certain predictors of first year college grade :
SAT 11 scores = 17%
GPA = 15.6%
SAT 1 = 13.3%
Fitting a least squares line :
y = First year college GPA
x = high school GPA
THE r² value which is Coefficient of determination is the percentage of explained variance given by the regression line. The r² value of GPA will the as given above 15.6%
r² = 15.6% = 15.6/100 = 0.156
Recall that Daniel's taxable income is $33,914. According to the single taxable income tax brackets for 2018, the amount of income tax that Daniel owes is____
A)$3,391.40
B)$3,501.16
C)$3,653.14
D)$3,879.18
E)$4,069.69
Answer: E. $4,069.69
Step-by-step explanation:
For individuals who have an income that's between $9,526 to $38,700, their tax rate is 12%.
Therefore, since Daniel's taxable income is $33,914. According to the single taxable income tax brackets for 2018, the amount of income tax that Daniel owes will be:
= 12% × $33,914
= 12/100 × $33,914
= 0.12 × $33,914
= $4,069.69
Answer: D)$3,879.18

What are m∠1 and m∠2?
Answer:
Angle 1 = 35
Angle 2 = 30
Answer B
Step-by-step explanation:
Angle 1)
You know the total angles in a triangle are 180
You also know that the angle across from 1, next to 115 has to be 180-115 (65) or , this gives you
180-80-(180-115)= 35
Angle 2 )
You know the total angles in a triangle are 180
You also know that the angle across from 85, next to 115 is the same value 65 as it was for the calculation of angle 1.
so this means
180-85-65 = 30

The supply function for a product is given by p = 40 + 100 underroot 2x + 9, where x is the number of units supplied and p is the price in dollars. If the price is increasing at a rate of $1 per month, at what rate is the supply changing when x = 20?
the supply changing when x=20 is 40
The window has the shape of a kite. How many square meters of glass were used to make the window?
Answer:
1568cm²
Step-by-step explanation:
28cm + 28cm = 56cm
35cm + 21cm = 56cm
56 × 56 = 3136cm²
3136cm² ÷ 2 = 1568cm²
HELPP!! The transformation functions R, S, T, U, and V are shown below
Answer:
Point T(x, y) is translated 71 units up and then rotated 180° about the origin
Point U(x, y) is rotated 90° counterclockwise, then translated 124 units up.
Point V(x, y) is reflected about the y axis, then translated 8831 units to the left.
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
If a point R(x, y) is vertical stretched by a factor of 38 followed by a horizontal stretch of 7, the new point is at R'(x/7, 38y). That is (x, y) ⇒ (x/7, 38y).
If a point S(x, y) is translated 9 units to the right, the new point is (x + 9, y), if it is reflected over the y axis, the new point is S'(-x-9, y). That is (x, y) ⇒ (-x-9, y).
If a point T(x, y) is translated 71 units up, the new point is at (x, y + 71), if it is rotated 180° about the origin, the new point is at T'(-x, -y - 71). That is (x, y) ⇒ (-x, -y - 71).
If a point U(x, y) is rotated 90° counterclockwise, the new point is at (-y, x), if it is then translated 124 units up, the new point is U'(-y, x + 124).
If a point V(x, y) is reflected about the y axis, the new point is at (-x, y), if it is then translated 8831 units to the left, the new point is V'(-x - 8831, y).

Which value from the set {3,10,90,108} will make the equation 3x + 3 = 33 true ?
Answer:
[tex]x = 10[/tex] will make the equation true
Step-by-step explanation:
Given
[tex]\{3,10,90,108\}[/tex]
[tex]3x +3= 33[/tex]
Required
Which is true for x
We have:
[tex]3x +3= 33[/tex]
Collect like terms
[tex]3x= 33 - 3[/tex]
[tex]3x= 30[/tex]
Solve for x
[tex]x = 30/3[/tex]
[tex]x = 10[/tex]

BRANLIEST TO CORRECT PERSON.. plss help!
Answer:
C
Step-by-step explanation:
When the expression has an equal sign there is only one solution
6x = 150
* divide each side by 6 *
6x / 6 = x
150 / 6 = 25
we're left with x = 25
The answer would be C, because the dot is in between 24 and 26 which would be 25 and x equals 25

Answer:
100.5 ft²
Step-by-step explanation:
The surface area of the cylinder is given by the formula ...
SA = 2πr(r +h) . . . . for radius r and height h
Using the given numbers, we find the area to be ...
SA = 2(3.14)(2 ft)(2 ft +6 ft) = 32(3.14) ft² ≈ 100.5 ft²
The surface area of the cylinder is about 100.5 square feet.
