[tex]46[/tex]
Step-by-step explanation:
Hey there,
Before solving the sum you have to know about the BODMAS theorem.
That means you have to solve this sum according to the BODMAS theory.
BODMAS theory is,
B - Brackets
O - Of
D - Division
M - Multiplication
A - Addition
S - Subtraction
Let us solve the sum now.
[tex]3 \times {2}^{3} + {5}^{2} - 18 \div 6 \\ 3 \times 8 + 25 - 18 \div 6 \\ 24 + 25 - 3 \\ 49 - 3 \\ = 46[/tex]
Hope this helps you.

5. Suppose a set of math test scores is normally distributed with a mean of 100 (you do not need to know the standard deviation to answer this question, but you may find it helpful to plug in a standard deviation of your choice). If you randomly select a sample of scores from this distribution, which of the following probabilities is higher? Explain your answer.
a. The probability of the sample mean falling between 100 and 105 with a sample of 25 scores.
b. The probability of the sample mean falling between 100 and 105 with a sample of 36 scores.
Answer:
A
Step-by-step explanation:
It is more likely because there is less of a chance of an outlier. Hope this helps.
The following ratio table has a mistake. Select the value that does not create an equivalent ratio. Ratio Table 1 2 3 6 5 10 10 12
Answer:
10 and 12
Step-by-step explanation:
10 and 12
if I divide 3 and 6 by 3 I get 1/2
if I divide 5 and 10 by 5 I get 1/2
1/2 is the first one listed
I cannot reduce 10/12 and get 1/2, I get 5/6
Jason, David, and Marcus each saved their allowance for four weeks. The ratio of total money
saved to number of weeks for each friend are shown in the table and graph. Which friend has
the greatest ratio of total money saved to number of weeks? Justify your response.
Answer:
David saved $15 per week
Jason saved $10 per week
Marcus saved $5 per week
(i divided y by x)
so David saved the most money throughout each week.
What is the solution of |2x+5|<19?
Answer:
[tex]2x + 5 < 19 \\ 2x < 19 - 5 \\ 2x < 14 \\ x < 7[/tex]
Answer:
The result can be shown in multiple forms.
Inequality Form:
−12< x < 7
Interval Notation:
(−12,7)
Step-by-step explanation:
first write |2x+5|<19 as a piece wise
2x+5≥0
To find the interval for the first piece, find where the inside of the absolute value is non-negative.
[tex]\frac{2x}{2}[/tex] ≥[tex]\frac{5}{2}[/tex] divide
x ≥−[tex]\frac{5}{2}[/tex] cancel common factor of 2
x ≥ −5/2.
To find the interval for the second piece, find where the inside of the absolute value is negative.
2x+5 < 0
substract by 5
2x < −5
divide by 2x
2x/2< −5/2
simplify to left side
x < −5 / 2
Simplify the right side.
x < −5/2
In the piece where 2x+5 is negative, remove the absolute value and multiply by −1
− (2x+5) < 19
Write as a piecewise.
{2x+5 <19 x ≥ − 5/2
− (2x+5) < 19 x <− 5/2
Simplify −(2x+5)<19.
{2x+5<19 x≥−5/2
−2x−5<19 x<−5/2
Solve 2x+5 < 19 when x ≥ −5/2.
2x+5<19 for x.
Move all terms not containing x to the right side of the inequality.
2x < 14
divide by 2
x < 7
Find the intersection of x < 7 and x ≥−5/2.
−5/2 ≤x <7
Solve −2x−5 <19 when x <−5/2.
Move all terms not containing x to the right side of the inequality.
−2x<24
divide by -2
x>−12
Find the intersection of x > −12 and x <−5/2.
Find the union of the solutions.
−12 < x < 7
A volunteer at the zoo is responsible for feeding the animals in 15 exhibits in the reptile house. This represents 20% of the total exhibits in the reptile house. How many exhibits are in the reptile house?
Answer:
75
Step-by-step explanation:
15 is 20% of the total.
The total is x since it is unknown.
20% of the total = 15
20% of x = 15
0.2x = 15
Multiply both sides by 5.
x = 75

The expected value from a single die roll Given the Conditions stated is $3
The expected value is calculated using the relation :
E(X) = X × P(X)The table of probabilities from a single roll :
X ___ 6 ___ 0 ___ 0 ___ 0 ___ 0 ___12P(X)_ 1/6__ 1/6 __ 1/6 __ 1/6 __ 1/6 __ 1/6The expected value calculation :
E(X) = X × P(X) E(X) = (6×1/6) + 0 + 0 + 0 + 0 + (12 × 1/6) E(X) = 1 + 2 = $3Therefore, the expected value of a single die roll is $3
