7. Sketch the graph of f(x) = 2(x - 1.5)2 + 3, then state the domain and range of the function (show all your
work). (4 points)
8. Determine the value of a given that (7, 6) satisfies the quadratic function f(x) = a(x – 5)2 +6. (Show all your
work). (2 points)
9514 1404 393
Answer:
7. D: (-∞, ∞); R: [3, ∞); see attached for a graph (red)
8. a=0; see attached for a graph
Step-by-step explanation:
7. The function is a polynomial, so its domain is all real numbers.
The parabola opens upward. It has a minimum value of 3. The range is y ≥ 3.
__
8. Putting the given point coordinates in the equation, we can solve for a.
f(7) = 6
6 = a(7 -5)² +6
0 = a(2²)
0 = a
The value of a is zero.
(The given point has the same y-value as the vertex, but is not the vertex. The function can only go through that point if it is a horizontal line (not a parabola).) The attachment shows a graph.
The weights of a certain brand of candies are normally distributed with a mean weight of 0.8544 g and a standard deviation of 0.0525 g. A sample of these candies came from a package containing 466 candies, and the package label stated that the net weight is 397.9 g. (If every package has 466 candies, the mean weight of the candies must exceed 397.9466
Required:
If 1 candy is randomly selected, find the probability that it weighs more than 0.8535 g. The probability is:_____
Answer:
The probability is 0.508 = 50.8%.
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.
Normally distributed with a mean weight of 0.8544 g and a standard deviation of 0.0525 g.
This means that [tex]\mu = 0.8544, \sigma = 0.0525[/tex]
If 1 candy is randomly selected, find the probability that it weighs more than 0.8535 g.
This is 1 subtracted by the pvalue of Z when X = 0.8535. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0.8535 - 0.8544}{0.0525}[/tex]
[tex]Z = -0.02[/tex]
[tex]Z = -0.02[/tex] has a pvalue of 0.492
1 - 0.492 = 0.508
The probability is 0.508 = 50.8%.

Answer:
90+42+x = 180
132+x=180
x=180-132
x=48
Answer:
48 DEGREES
Step-by-step explanation:
First you need to find the other two angles : 42 + 90 = 132 ( the 90 comes from the little square like shape on the other angle).
So x = 180 - 132 = 48 ( we use 180 because it is the sum of interior angles of a triangle.

4/13= 10/32
Answer:
True
True
True
False
Step-by-step explanation:
15/18 simplified is 5/6
3/5 multiply both numerator and denominator by 20 to get 60/100
20/14 simplified is 10/7
4/13 multiply both by 2.5 to get 10/32.5 and 32.5 does not equal 32

Suppose Y is a random variable with = 0, and = 1, skewness = 0, and kurtosis = 100. Explain why n random variables drawn from this distribution might have some large outliers. A. There might be some outliers because the skewness of the distribution equals 0. B. There might be some large outliers because both, the population variance and standard deviation , are equal to 1. C. There might be some outliers because the kurtosis of the distribution equals 100. D. There might be some large outliers because the population equals 0.
Answer:
C. There might be some outliers because the kurtosis of the distribution equals 100.
Step-by-step explanation:
Kurtosis is about the tail of the distribution. High kurtosis means that the data is heavily in the tails or outliers. The kurtosis of the distribution is 100 means there are outliers and the data lies in the tails. The skewness of the data set is determined by the outliers.

Line I is parallel to line m. If the
measure of 26 is 75°, what is the
measure of Z2?
1/2
4/3
5/6 = 75°
78
Answer:
75°
Step-by-step explanation:
All parallel lines will meet their transversal (the line going through them) at the same angle. We can imagine sliding line m up to line l until the two are overlapping, and naturally all of those angles at the intersection will overlap, too. ∠6 will overlap ∠2, so the two angles are congruent. If m∠6 = 75°, then m∠2 = 75°!

i got a question where it gave the slope of -1/2 and a point of (-10,3) i need to find the equation of the line
9514 1404 393
Answer:
y -3 = -1/2(x +10)
Step-by-step explanation:
Given a point and a slope, it is reasonable to use the point-slope form of the equation for a line.
y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)
Your line has slope m = -1/2 through point (h, k) = (-10, 3). Putting these values into the appropriate form your equation is ...
y -3 = -1/2(x +10) . . . . point-slope form equation
__
y = -1/2x -5 +3 . . . . eliminate parentheses, add 3
y = -1/2x -2 . . . . . . . . . slope-intercept form equation
Find the probability that when a couple has five children, at least one of them is a boy. (assume that boys and girls are equally likely.)
Answer:
The easiest way to figure this is to find P(no girls in 5 births) = (1/2)^5 = 1/32 -------------- The P(at least one girl in 5 births) = 1 - 1/32 = 31/32
The probability that when they have five children, at least one of them is a boy is 31/32
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome:
The probability that a couple will have a boy or girl among the five children = 1/2
If they gave birth to 5 children:
The probability that when they have five children, at least one of them is a boy = 1 - (1/2)^n where:
n is the total number of children
The probability that when they have five children, at least one of them is a boy = 1 - (1/2)ⁿ
The probability that when they have five children, at least one of them is a boy = 1 - (1/2)⁵
The probability that when they have five children, at least one of them is a boy = 1- 1/32 = 31/32
Hence the probability that when they have five children, at least one of them is a boy is 31/32
