Answer: 6/36
Step-by-step explanation:
When tossing two number cubes, you can get such sample space
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
There are 36 possible outcomes. Only (1,1), (2,2), (3,3), (4,4), (5,5), and (6,6) use the same number twice.
Hence, the probability that you roll two numbers that are the same in a row is 6/36, or in simplified form, 1/6.
Hope that helps! :)
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

There are 4 green marbles and 7 sliver marbles in a bag. You randomly choose one of the marbles. What is the probability of choosing a green marble?
Answer:
4/11
Step-by-step explanation:
there are 4 green out of 11 total
Answer:
4/11 is the probability you will get a green marble
Step-by-step explanation:
First you must determine the denominator by adding 4 and 7 to make the total number of marbles
4 + 7 = 11.
Next, you have 4 green marbles so you make it 4/11
Lastly, have a great day!

polygon have?
Check all that apply.

In a regular tessellation 3,4,6 sides can be tessellating regular
polygon.
What is regular polygon?A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.
First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.
A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.
A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

A savings account starts with $250. It earns $30 in 2 years. Find the
rate of interest
Answer:
The annual interest rate is 6%
Step-by-step explanation:
Use the formula for simple interest: i = prt.
Set i = prt equal to $30: $30 = prt
Solve this for r:
$30
r = -------------- = ($30) / ($500) = 0.06
$250(2)

Step-by-step explanation:
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.

Find four consecutive even integers such that if the sum of the first and third was multiplied by 2, the result is 20 less than three times the fourth.
xAnswer:
-10 -8 -6 -4
Step-by-step explanation:
The numbers are
first =x
second= x+2
third=x+4
4th= x+6
2(x + (x+4)) = 3(x+6)-20
4x+8 = 3x+18–20
4x-3x=18–20–8
x=-10
So the numbers are -10, -8, -6, -4

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

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
