Answer: r = — 2
Step-by-step explanation:
Suppose each license plate in a certain state has one digit, followed by four letters, followed by one digit. The letters F, O, S, and X and the digit 0 are not
used. So, there are 22 letters and 9 digits that are used. Assume that the letters and digits can be repeated. How many license plates can be generated using
this format?
Each digit can be 1 of 9 numbers.
Each letter can be 1 of 22 letters.
To find total combinations, Multiply each number of choices by each number of choices.
9 x 22 x 22 x 22 x 22 x 9 = 18,974,736 total combinations

A scientist measures the heights of sunflower plants. The histogram shows the results. Which statement is correct?
Answer:
C. The data are skewed to the left, so the median height is greater than the mean height.
Step-by-step explanation:
The answer is C because the mean is typically less than the median when the data is skewed left.
In Frank's piggy bank, there are only quarters
and dimes. He has 37 coins, and has a total of
$5.50. How many quarters does he have?
Answer:
12 quarters
Step-by-step explanation:
number of quarters ---------x
number of dimes ------------y
therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1
0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2
equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12
there are 12 quarters

How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means

All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.

If two points known on the line AB in the coordinate plane is (7,15) and (18,42), calculate the following..
A) the slope of the line AB
B) The length of the line AB
Answer:
Slope = 27/11
AB = 29.15 u
Step-by-step explanation:
Given :-
Two points are given to us .The points are A(7,15) and B(18,42)To Find :-
The slope of the line .The length of line AB .We can find the slope of the line passing through the points [tex]( x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex]as ,
[tex]\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}[/tex]
Plug in the respective values ,[tex]\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}[/tex]
Hence the slope of the line is 27/11 .
[tex]\rule{200}2[/tex]
Finding the length of AB :-
We can find the distance between them by using the Distance Formula .[tex]\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }[/tex]
Hence the length of AB is 29.15 units .

Answer:
Step-by-step explanation:
This is all about the symbols and how they are pronounced; it's also about what they mean in less formal language.
h is less than 21: h < 21
h is greater than or equal to 21: [tex]h \ge 21[/tex] (notice the half-an-equal sign under the greater than sign)

h is greater than 21: h > 21

Albert's rectangular garden is 6ft by 3ft. He wants to lengthen both dimensions by the same number of feet so that the new area will be 40 square feet. What will be the new dimensions?
Answer:
8 and 5
Step-by-step explanation:
Let the number of feet added = x
(x + 6) ( x + 3) = 40 Remove the brackets
x^2 + 6x + 3x + 18 = 40 Combine like terms on the left
x^2 + 9x + 18 = 40 Subtract 18 from both sides
-18 -18
x^2 + 9x = 22 Subtract 22 from both sides
x^2 + 9x - 22 = 0
This quadratic factors
(x + 11)(x - 2)
x + 11 = 0
x = - 11 which makes not sense.
x - 2 = 0
x = 2
The answer is x = 2

Answer:
Hello! answer: 28
Step-by-step explanation:
This is a complementary angle! So it will add up to 90 degrees so all we have to do is 90 - 62 so 90 - 62 = 28 so 28 is our answer!
HELPPP PLZZZZ ASAP IS PLEASEEE DONT SEND A FILE AT ALL
Answer:
I am telling I am new to this
The mean work week for engineers in start-up companies is claimed to be about 63 hours with a standard deviation of 5 hours. Kara, a newly hired engineer hopes that it's not (she wants it to be shorter). She asks 10 engineers in start-ups for the lengths of their mean work weeks. Their responses are 70; 45; 55; 60; 65; 55; 55; 60; 50; 55. a. Is the newly hired engineer testing a mean or a proportion? proportion mean b. The null hypothesis (or company claim), in symbols, is μ = . c. If the claim is correct, what is the probability that a sample mean would be as low as Kara's mean? % Give your answer as a percentage accurate to one decimal place. d. If Kara will accept the 63 hours as the real average so long as there's at least a 10% chance the sample average value could be as low as hers, should she accept the claim?
Answer:
a. Mean
b. μ = μ₀
c. 11.5%
d. Yes
Step-by-step explanation:
The given parameters are;
The mean work week for engineers, μ₀ = 63 hours
The standard deviation, σ = 5 hours
The number of engineers in Kara's sample, n = 10 engineers
The responses given by the 10 engineers are;
70; 45; 55; 60; 65; 55; 55; 60; 50; 55
a. The given information which the newly hired is hoping to find out that it is not is the mean
b. The null hypothesis which is that the company claim is correct, is therefore;
Null hypothesis, H₀; μ = μ₀ = 63 hours
c. Kara's mean, [tex]\overline x[/tex] is found as follows;
[tex]\overline x[/tex] = (70 + 45 + 55 + 60 + 65 + 55 + 55 + 60 + 50 + 55)/10 = 57
[tex]\overline x[/tex] = 57 hours
The Z-score is therefore;
[tex]Z=\dfrac{\overline x-\mu }{\sigma }[/tex]
Z = (57 - 63)/5 = -1.2
From the Z-table, we have;
The p-value for P([tex]\overline x[/tex] ≤ 57) = P(Z ≤ -1.2) = 0.11507
The probability as a percentage given to one decimal place, that the mean would be as low as Kara's mean, P([tex]\overline x[/tex] ≤ 57) = 11.5%
d. Given that the percent percentage chance (11.5%) that the mean could be as low as hers ([tex]\overline x[/tex] = 57 hours) is higher than 10%, she should accept the claim.
