Answer:
16
Step-by-step explanation:
The altitude of the triangle is 12/21 = 4/7 of the marked side. If we assume that the marked sides are the ones that are corresponding, then ...
x = (4/7)(28)
x = 16

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

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

A contestant on the Cash Show just answer a trivia question correctly. This question had 5 multiple choice answers. It is estimated that 10% of the general population know the correct answer to this question. What is the probability that contestant knew the answer rather than guessed it
Answer:
10% probability that contestant knew the answer rather than guessed it
Step-by-step explanation:
Since it is estimated that 10% of the general population know the correct answer to this question, for each contestant, there is a 10% probability that he knew the answer rather than guessing.
So the answer is 10% probability that contestant knew the answer rather than guessed it
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

You are curious why some apartments in West Campus cost more to rent than others. So you sample 30 one-bedroom apartments from across different West Campus apartment buildings and record the monthly rent (in dollars), along with the following explanatory variables: Area - square feet of living space in the apartment Age - how many years old the building that contains the apartment is Parking - whether or not the apartment comes with a parking space You ran a linear regression model predicting monthly rent and including the main effects of all three explanatory variables.
Required:
What is the population of interest for this study?
Answer:
the monthly rents of the apartments
Step-by-step explanation:
In the field of statistics, the population of interest may be defined as the group or the population from which the experimenter or the researcher tries to make conclusions or draw their results.
In the context, I am interested to study the cost of the rented house that is more than others in the West Campus area.
So I recorded the monthly rents of the apartments from a sample of 30 one bedroom apartments.
Therefore, the population of interest for my study here is the monthly rents recorded from the sample of one bedroom apartments.

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

Answer: A
Step-by-step explanation:
7. A particular compound decays according to the equation y = ae-0.0736t, where tis in days. Find the
half-life of this compound.
a. about 9.1 days b. about 9.4 days
c. about 6.8 days d. about 7.4 days
Answer:
b. about 9.4 days
Step-by-step explanation:
Amount of the compound:
The amount of the compound after t days is given by the following equation:
[tex]y(t) = ae^{-0.0736t}[/tex]
The initial amount is:
[tex]y(0) = a[/tex]
Half-life:
t for which [tex]y(t) = 0.5a[/tex]. So
[tex]y(t) = ae^{-0.0736t}[/tex]
[tex]0.5a = ae^{-0.0736t}[/tex]
[tex]e^{-0.0736t} = 0.5[/tex]
[tex]\ln{e^{-0.0736t}} = \ln{0.5}[/tex]
[tex]-0.0736t = \ln{0.5}[/tex]
[tex]t = -\frac{\ln{0.5}}{0.0736}[/tex]
[tex]t = 9.42[/tex]
So about 9.4 days, and the answer is given by option b.
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).
