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

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).

1a. [1 mark] The price per kilogram of tomatoes, in euros, sold in various markets in a city is found to be normally distributed with a mean of 3.22 and a standard deviation of 0.84. Find the price that is two standard deviations above the mean price.
Answer:
The price that is two standard deviations above the mean price is 4.90.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 3.22 and a standard deviation of 0.84.
This means that [tex]\mu = 3.22, \sigma = 0.84[/tex]
Find the price that is two standard deviations above the mean price.
This is X when Z = 2. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2 = \frac{X - 3.22}{0.84}[/tex]
[tex]X - 3.22 = 2*0.84[/tex]
[tex]X = 4.9[/tex]
The price that is two standard deviations above the mean price is 4.90.

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

Step-by-step explanation:
all working is above
hope thats of help
The y- intercept is 3.
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
18x−6y=12
Writing the above equation in slope- intercept form
6y = 18x - 12
y= 18x /6 - 12/ 6
y= 3x - 2.
So, the slope of perpendicular line is -1/3 and passes through (6, 1)
y= mx+ c
1 = -1/3 (6) + c
1 = -2 + c
c= 3
Hence, the y- intercept is 3.

Suppose you have a weighted coin in which heads comes up with probability 3/4 and tails with probability 1/4. If you flip heads, you win $2, but if you flip tails, you lose $1. What is the expected win of a con flip in dollars
Answer:
The expected win of a coin flip in dollars is 1.25.
Step-by-step explanation:
To find the expected win of a coin flip, we multiply the probability of each outcome by their earnings, and then add them.
We have that:
3/4 probability of heads. If heads, you win $2.
1/4 probability of tails. If tails, you lose $1.
What is the expected win of a coin flip in dollars?
[tex]E = 2\frac{3}{4} - 1\frac{1}{4} = \frac{2*3 - 1*1}{4} = \frac{6-1}{4} = \frac{5}{4} = 1.25[/tex]
The expected win of a coin flip in dollars is 1.25.
