Which word best describes 8(2x +4)
Final answer:
The word that best describes 8(2x + 4) is multiplication. When we multiply a number by an expression, we distribute the multiplication to each term in the expression. Simplifying further, 8(2x + 4) becomes 16x + 32.
Explanation:
The word that best describes 8(2x + 4) is multiplication. In this expression, the number 8 is being multiplied by the expression 2x + 4. When we multiply a number by an expression, we distribute the multiplication to each term in the expression. Therefore, the expression becomes 8 * 2x + 8 * 4.
Simplifying further, we get 16x + 32. So, the word that best describes 8(2x + 4) is multiplication.

When Sally went bowling her scores were 108, 72, and 95. If she bowls a 4th game, what will her score need to be to give her an average of 91?
To achieve an average score of 91, Sally needs to bowl an 89 in her fourth game, calculated by subtracting her current total score of 275 from the desired total of 364 points.
To calculate the score Sally needs in her fourth game to achieve an average of 91, we first need to determine the total points she needs after four games. We can calculate the required total points by multiplying the desired average score by the number of games:
91 × 4 = 364 total points
Next, we add up the scores from Sally's first three games:
108 + 72 + 95 = 275 points
Finally, we subtract the sum of her first three games from the total required points to find the score Sally needs in her fourth game:
364 - 275 = 89 points
Therefore, Sally needs to bowl a score of 89 in her fourth game to achieve an average of 91.

b) Eight pounds of peanuts cost $24.00. Six pounds of walnuts cost half as much. Which is more expensive and by how much?
c) Eight pounds of peanuts cost $24.00. Six pounds of walnuts cost half as much. How much will Jim pay for 3 lbs of peanuts and 6 lbs of walnuts?
d) Write “four hundred dollars and seventy two cents”... as a fraction (and then reduce).
I will give brainliest if correct. Thanks.
Answer:
b) Peanuts, $1 per lb
c) $21
Step-by-step explanation:
b)
Peanuts= 12*2=$24
Walnuts= 6*2=$12
1 lb of peanut= 3 lb
1 lb of walnut= 2 lb
24 is greater than 12
3-2=1
$1 greater per lb
c)
1 lb of peanut= 3 lb
1 lb of walnut= 2 lb
3*3=9
2*6=12
9+12= $21

The table shows the results of spinning a spinner several times. (Don’t mind my answer)
The experimental probability of spinning a B or a C is [tex]\( \frac{1}{4} \)[/tex].
To find the experimental probability of spinning a B or a C, we need to sum up the frequencies of outcomes B and C and then divide that by the total number of spins.
Given frequencies:
Outcome A: 3
Outcome B: 2
Outcome C: 1
Outcome D: 4
Outcome E: 2
Total frequency of B and C: 2 (from outcome B) + 1 (from outcome C) = 3
Total number of spins: Sum of all frequencies = 3 + 2 + 1 + 4 + 2 = 12
Experimental probability of spinning a B or a C: [tex]\(\frac{\text{Total frequency of B and C}}{\text{Total number of spins}} = \frac{3}{12} = \frac{1}{4}\)[/tex]
So, the experimental probability of spinning a B or a C is [tex]\(\frac{1}{4}\)[/tex].

Justin is exchanging dollars for rolls of quarters and rolls of dimes at a bank. Each roll of quarters has a value of $10 and each roll of dimes has a value of $5. He exchanges $90 and receives 11 rolls of coins. How many of each type of roll of coins did he receive?
Answer:
Justin got 7 rolls of quarters and 4 rolls of dimes.
Step-by-step explanation:
Let the roll of quarters be x
Let the rolls of dimes be y
As total money received is $90, the equation becomes;
[tex]10x+5y=90[/tex] .....(1)
And he got 11 roll of coins, so equation becomes;
[tex]x+y=11[/tex] or [tex]x=11-y[/tex] .... (2)
Substituting the value of x from (2) in (1)
[tex]10(11-y)+5y=90[/tex]
[tex]=> 110-10y+5y=90[/tex]
[tex]=> -5y=-110+90[/tex]
[tex]=> -5y=-20[/tex]
So, y = 4
As [tex]x=11-y[/tex]
So, [tex]x=11-4[/tex]
x = 7
Hence, Justin got 7 rolls of quarters and 4 rolls of dimes.

What is the size of the obtuse angle CBA
Answer:
[tex]m<CBA=102\°[/tex]
Step-by-step explanation:
we know that
The internal angle of an equilateral triangle is equal to [tex]60\°[/tex]
The internal angle of a square is equal to [tex]90\°[/tex]
To find the internal angle of a regular pentagon, apply the formula
[tex]S=[(n-2)180\°]/n[/tex]
where
n is the number of sides (n=5)
substitute
[tex]S=[(5-2)180\°]/5=108\°[/tex]
therefore
In this problem
[tex]m<CBA+60\°+90\°+108\°=360\°[/tex]
[tex]m<CBA+258\°=360\°[/tex]
[tex]m<CBA=360\°-258\°=102\°[/tex]

Sam intends to roll a six sided cube 100 times. What is the probability model he can use to predict whether or not each roll will give a result that is not a prime number?
The outcomes of rolling fair six sided die is [tex] \{1,2,3,4,5,6\} [/tex]. The prime numbers in the above outcomes are [tex] \{2,3,5\} [/tex]. The probability of not rolling a prime number is [tex] p=\frac{3}{6}= 0.5 [/tex].
Each trial is independent.
In the given experiment of 100 trials, the binomial probability model can be used to predict the number of occurrence of non-prime numbers (X). The probability mass function is
[tex] P(X=x)=C(100,x)p^x(1-p)^{100-x},x=0,1,2,3,...,100 [/tex]. Since [tex] p=0.5,1-p=0.5 [/tex]
[tex] P(X=x)=C(100,x)0.5^x(0.5)^{100-x},x=0,1,2,3,...,100 \\
P(X=x)=C(100,x)(0.5)^{100},x=0,1,2,3,...,100 [/tex]
