The probability that Grant will select a blue sock and then a green sock = [tex]\frac{8}{95}[/tex].
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.
The probability that Grant will select a blue sock and a green sock =
= Probability of choosing a blue sock * Probability of choosing a green sock out of the remaining socks
= [tex]\frac{Number\ of\ blue\ socks}{Total\ number\ of\ socks} * \frac{Number\ of\ green\ socks\ out\ of\ remaining\ socks }{Total\ number\ of\ remaining\ socks}[/tex]
= [tex]\frac{4}{20} * \frac{8}{19} = \frac{8}{95}[/tex]

There are 110 calories per 177.4 grams of Cereal X. Find how many calories are in 238.5 grams of this cereal
Answer: 147.87 calories
Step-by-step explanation:
Let the amount of calories in 238.5 grams of this cereal be represented by x.
Based on the information given, we can form an equation as:
110/177.4 = x/238.5
Cross multiply
177.4 × x = 238.5 × 110
x = (238.5 × 110) / 177.4
x = 147.87
Therefore, there are 147.87 calories in 238.5 grams of this cereal.

Answer:
∠ GHE = 40°
Step-by-step explanation:
∠ IHE and ∠ GHE are adjacent angles and are supplementary, then
∠ GHE + ∠ IHE = 180°
∠ GHE + 140° = 180° ( subtract 140° from both sides )
∠ GHE = 40°

Answer:
Option 3 or Option 4.
Step-by-step explanation:
I have this doubt because actually, a rhombus with a right angle (one) is not necessarily a square. Some rhombuses have one right angle and are still not squares. Now, if the four angles are right, it is a square, but this only says one.
On other hand, a parallelogram with congruent diagonals isn't a square necessarily either. Rectangles have congruent diagonals and are parallelograms.
In case you only can answer with one, I'll say is option 3, hope it helps!

John is placing cement tiles for a patio in a rectangle surrounding a
rectangular fire pit. The fire pit has a width of x ft and a length that is 4
times the width. The entire patio is 9 ft wider and 13 ft longer than the fire
pit. What is the area that he will need to buy tiles for?
Answer:
31x + 55 sq. ft.
Step-by-step explanation:
Width of Fire Pit = x ft. Length of Fire Pit = 4x ft.
Width of Patio = x + 5 ft. Length of Patio = 4x + 11 ft. Area of Fire pit = 4x * x = 4x² sq, ft.
Total Area of Rectangular Patio (including Fire pit) = (4x + 11)(x+5)
= 4x² + 31x + 55 sq. ft.
Area for which tiling is done = Area of Rectangular patio - Area of fire pit
= 4x² + 31x + 55 - 4x²
= 31x + 55 sq. ft.
Esther uses 9.4 pints of blue paint and white paint to paint her bedroom walls. 3 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
3.76
Step-by-step explanation:
Esther uses 9.4 pints of blur paint and white pant for her bedroom
3/5 of this amount is blue paint while the rest is white paint
3/5
= 0.6×100
= 60
Therefore the amount of white paint can be calculated as follows
40/100 × 9.4
= 0.4×9.4
= 3.76
What is the answer for, A metal bar 8.15 ounces 93% of the bar is sliver. How many ounces of silver are in the bar? ( round to the nearest thousandth)?
Answer:
7.580 ounces
Step-by-step explanation:
The question is asking how many ounces of silver are in the bar. We know that 93% of the bar is silver. The bar is 8.15 ounces. This means we need to find 93% of 8.15. Let's set up an equation.
93% of 8.15
93/100 • 8.15
0.93 • 8.15
= 7.5795
Round to the nearest thousandth.
7.580 ounces

Q1 : Gina writes the letters of the word PROBABILITY on separate cards. She picks one card at random. What is the probability that the card Gina selects is:
a) The letter B
b) A vowel
c) A letter before M in the alphabet?
Answer:
2/11
4/11
6/11
Step-by-step explanation:
probability the letter B = number of times b appears in the word / total number of alphabets
total number of alphabets = 11
number of times b appears in the word = 2
2/11
a vowel = total number of vowels in the word / total number of alphabets
vowels include = a,e,i,o,u
vowels in the word = a, o, i
total number of vowels in the word = 4
4/11
A letter before M in the alphabet = total number of alphabets before m in the word / total number of alphabets
letters before m = A, B, C, D, E, F, G, H, I, J, K, L
letters before m in the word = b,a, i , l
number of words before m = 6/11

f(3) = 12 for a geometric sequence that is defined
recursively by the formula f(n) = 0.5 ∙ f(n – 1), where
n is an integer and n > 0.
Write the equation in explicit form.
Answer:
[tex]f(n) = 96 * 0.5^n[/tex]
Step-by-step explanation:
Given
[tex]f(3) = 12[/tex]
[tex]f(n) = 0.5 * f(n-1)[/tex]
Required
Write as an explicit function
When n = 3, we have:
[tex]f(3) = 12[/tex]
[tex]f(3) = 0.5 * f(3-1)[/tex]
[tex]f(3) = 0.5 * f(2)[/tex]
Substitute: [tex]f(3) = 12[/tex]
[tex]12 = 0.5 * f(2)[/tex]
Solve for f(2)
[tex]f(2) = 12/0.5[/tex]
[tex]f(2) = 24[/tex]
So, we have;
[tex]f(3) = 12[/tex]
[tex]f(2) = 24[/tex]
Since it is a geometric sequence, calculate the common ratio (r)
[tex]r = \frac{f(3)}{f(2)}[/tex]
[tex]r = \frac{12}{24}[/tex]
[tex]r = 0.5[/tex]
Calculate the first term using:
[tex]r = \frac{f(2)}{f(1)}[/tex]
Solve for f(1)
[tex]f(1) = \frac{f(2)}{r}[/tex]
[tex]f(1) = \frac{24}{0.5}[/tex]
[tex]f(1) = 48[/tex]
The explicit function is then calculated as:
[tex]f(n) = f(1) * r^{n-1[/tex] ----nth term of a gp
[tex]f(n) = 48 * 0.5^{n-1[/tex]
Split the exponent
[tex]f(n) = 48 * \frac{0.5^n}{0.5^1}[/tex]
[tex]f(n) = 48 * \frac{0.5^n}{0.5}[/tex]
[tex]f(n) = 96 * 0.5^n[/tex]

Dan bought 35 pieces of candy. He gave 4 pieces to each of his friends. He only has 3 pieces left. Which equation, when solved for
X, gives the number of friends?
Answer:
35 - 4x = 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
35−4x=3
35+−4x=3
−4x+35=3
Step 2: Subtract 35 from both sides.
−4x+35−35=3−35
−4x=−32
Step 3: Divide both sides by -4.
-4x/−4 = −32/ −4
x=8
Answer:
8 friends
Step-by-step explanation:
4 doesn't go evenly to 9 ppl so it would be 8 friends and 3 extra pieces

A storage shed with a flat roof is 12 feet long by 9 feet wide by 4 1/2 feet tall.
How many cubic feet of storage space does the shed enclose?
Answer:
To get the volume of the shed in yards, multiply 4*3*2.5=30
since one cubic yard is equal to 27 cubic feets, multiply 27 with 30 to get the volume in cubic feets 27*30=810

The ratio of dogs to cats in the neighborhood was 3 to 7. If a total of 210 dogs and cats were in the neighborhood, how many cats were there? Complete the statement by providing the correct response in number form.
Answer:
147 cats
Step-by-step explanation
There are 3 dogs/ 7 cats
3x + 7x = 210
10x = 210
210 ÷ 10 = 21
Therefore,
x = 21.
dogs would be 3x (3 x 21) = 63
cats would be 7x (7 x 21) = 147
find the area of the composite shape
Answer:
96 m²
Step-by-step explanation:
To calculate the area of a composite shape, you must divide the shape into rectangles, triangles, or other shapes.
A = l × w
L = length
W = width
Find the area and then add the areas back together.
12m × 8m
= 96 m²
The area of the composite shape is 96 m²
(−7x 2 −4)+(−7x 2 −6x−2)
-20
Explanation:
( − 7 ^ 2 − 4 ) + ( − 7 ^ 2 − 6 − 2 )
Eliminate the redundant parentheses, subtract the numbers which will get you, combine like terms, rearrange terms, then your solution is:
− 1 4 2 −6 −6
Figure that problem out then you will get -20.
Answer:
−14x^2 − 6x - 6
Step-by-step explanation:
(−7x 2 −4)+(−7x 2 −6x−2) should be written as (−7x^2 −4) + (−7x^2 −6x−2). The " ^ " symbol denotes exponentiation. 7x^2 means "7 times the square of x." We can immediately remove the parentheses, obtaining:
−7x^2 −4 −7x^2 − 6x − 2
Our next step is to combine like terms. For example, -7x^2 appears twice, with the same (negative) sign; summing these up results in -14x^2.
Immediately after doing that, we have:
−14x^2 −4 − 6x − 2
and need to combine the constants -4 and -2:
−14x^2 −6 − 6x
Finally, we write these terms in descending powers of x:
−14x^2 − 6x - 6
