Describe how to find the vertex of a parabola if you are given the equation
Answer:
The vertex of a parabola is (h,k)
Step-by-step explanation:
The vertex form of a parabola is y=a(x-h)^2+k where a is the stretch/compression factor and (h,k) is the vertex. So to find the vertex, you will need (h,k) which represents the horizontal and vertical shift of the parabola

A jar contains 38 red marbles numbered 1 to 38 and 38 blue marbles numbered 1 to 38 a marble is drawn at random from the jar
Answer:
[tex]P(Red) = 0.50[/tex]'
[tex]P(Odd) = 0.50\\[/tex]
Step-by-step explanation:
Given
[tex]Red = 38[/tex]
[tex]Blue = 38[/tex]
Required (Missing part of the question)
(a) The marble is red. (b) The marble is odd-numbered
Solving (a): Probability of Red.
This is calculated as:
[tex]P(Red) = \frac{Red}{Total}[/tex]
[tex]P(Red) = \frac{38}{38+38}[/tex]
[tex]P(Red) = \frac{38}{76}[/tex]
[tex]P(Red) = 0.50[/tex]
Solving (b): Probability of Odd
Since each marble type is numbered 1 to 38, then half of it are odd.
i.e. 19 odd numbered red marbles and 19 odd numbered blue marbles.
So, the probability of odd is:
[tex]P(Odd) = \frac{Odd}{Total}[/tex]
[tex]P(Odd) = \frac{19+19}{38+38}[/tex]
[tex]P(Odd) = \frac{38}{76}[/tex]
[tex]P(Odd) = 0.50\\[/tex]
Find the value of x.

(23x+1)
52°
3
Answer:
Step-by-step explanation:
Adjacent angles when a line crosses another line must have a sum of 180 degrees.
52+2^(3x+1)=180
2^(3x+1)=128, 128=2^7 so
2^(3x+1)=2^7 which means
3x+1=7
3x=6
x=2

The bases of the two similar triangular prisms shown below are equilateral triangles.
What is the value of x, an edge length of the larger prism in centimeters?
9514 1404 393
Answer:
28 cm
Step-by-step explanation:
For the similar figures, a proportion can relate the side lengths.
x/(7 cm) = 11.2/2.8
x = (7cm)(11.2/2.8) = 28 cm
The value of x is 28 cm.

A coffee pot had 1
1/2 pints of coffee.
After a mug was
filled, there were 1
pint left in the pot.
How many ounces of
coffee were in the
mug?
Answer:
8 ounces
Step-by-step explanation:
Since there was 1 pint left, that means the mug had 1/2 pints of coffee.
Now, convert this to ounces. There are 16 ounces in a pint, so we can find how many ounces there were by multiplying 16 by 1/2
16(1/2)
= 8
So, there were 8 ounces of coffee in the mug
If f(x) = 3x - 7, find f(-1)
125% of what number is 20
Answer:
16
Step-by-step explanation:
We can rewrite this as 125/100 · x = 20
This works because a percentage is out of 100, which means 125% is 125/100. "Of" usually means multiplied, and "what number" is the variable.
Now we can simplify this
125/100 · x = 20
5/4 · x = 20
x = 16

Calculate the sample mean and sample variance for the following frequency distribution of heart rates for a sample of American adults. If necessary, round to one more decimal place than the largest number of decimal places given in the data. Heart Rates in Beats per Minute Class Frequency 51 - 58 6 59 - 66 3 67 - 74 11 75 - 82 13 83 - 90 4
Answer:
[tex]Mean = 68.9[/tex]
[tex]s^2 =18.1[/tex] --- Variance
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}{Class} & {51-58} & {59-66} & {67-74} & {75-82} & {83-90} \ \\ {Frequency} & {6} & {3} & {11} & {13} & {4} \ \end{array}[/tex]
Solving (a): Calculate the mean.
The given data is a grouped data. So, first we calculate the class midpoint (x)
For 51 - 58.
[tex]x = \frac{1}{2}(51+58) = \frac{1}{2}(109) = 54.5[/tex]
For 59 - 66
[tex]x = \frac{1}{2}(59+66) = \frac{1}{2}(125) = 62.5[/tex]
For 67 - 74
[tex]x = \frac{1}{2}(67+74) = \frac{1}{2}(141) = 70.5[/tex]
For 75 - 82
[tex]x = \frac{1}{2}(75+82) = \frac{1}{2}(157) = 78.5[/tex]
For 83 - 90
[tex]x = \frac{1}{2}(83+90) = \frac{1}{2}(173) = 86.5[/tex]
So, the table becomes:
[tex]\begin{array}{cccccc}{x} & {54.5} & {62.5} & {70.5} & {78.5} & {86.5} \ \\ {Frequency} & {6} & {3} & {11} & {13} & {4} \ \end{array}[/tex]
The mean is then calculated as:
[tex]Mean = \frac{\sum fx}{\sum f}[/tex]
[tex]Mean = \frac{54.5*4+62.5*3+70.5*11+78.5*13+86.5*4}{6+3+11+13+4}[/tex]
[tex]Mean = \frac{2547.5}{37}[/tex]
[tex]Mean = 68.9[/tex] -- approximated
Solving (b): The sample variance:
This is calculated as:
[tex]s^2 =\frac{\sum (x - \overline x)^2}{\sum f - 1}[/tex]
So, we have:
[tex]s^2 =\frac{(54.5-68.9)^2+(62.5-68.9)^2+(70.5-68.9)^2+(78.5-68.9)^2+(86.5-68.9)^2}{37 - 1}[/tex]
[tex]s^2 =\frac{652.8}{36}[/tex]
[tex]s^2 =18.1[/tex] -- approximated

8x = 24
x = 3
Answer:
x = 3
Step-by-step explanation:
Multiply x by 8 to get 8x
Multiply 6 by 4 to get 24
Place 8x and 24 into an equation to get 8x = 24
Divide 8x and 24 by 8
The 8 from 8x is canceled out, leaving the answer:
