Answer:
542.5
Step-by-step explanation:
Calculate the volume of a rectangular object by multiplying the length, width and height together. For example, if the length is 80 cm, the width is 7.75 cm, and the height is 7.5 cm, the volume is 80 x 2 x 7.5, or 7.75 cm^542.5

the longest side of a triangle is 10 cm which group of the line segments could form the other two sides of the triangle
5 cm and 5 cm
7 cm and 8 cm
9 cm and 10 cm
4 cm and 4cm
Answer:
7 cm and 8 c
Step-by-step explanation:
7 cm and 8 cm. Why? Because both are shorter than the longest side (10 cm) but add up to more than 10 cm.
solve the equation x- 1/4 = 3/8
Answer:
x = 5/8
Step-by-step explanation:
x - 1/4 = 3/8
Add 1/4 to both sides.
x - 1/4 + 1/4 = 3/8 + 1/4
x = 3/8 + 2/8
x = 5/8
Answer:
5/8

Step-by-step explanation:
Suppose that mean retail price per gallon of regular grade gasoline is 3.53 with a standard deviation of and that the retail price per gallon has a bell-shaped distribution. NOTE: Please use empirical rule approximations for this problem. a. What percentage of regular grade gasoline sells for between and per gallon (to decimal)
Answer:
Incomplete question, but I gave a guide to solve using the Empirical Rule.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
It is also important to note that the normal distribution is symmetric. This means of the 68% of the measures are within 1 standard deviation of the mean, for example, 68/2 = 34% are between 1 standard deviation below the mean and the mean, and 34% are between the mean and 1 standard deviation above the mean.
In this question:
You take the mean and the standard deviation. Then you take both bounds that the percentage asks, and see how many standard deviations each are from the mean, and you then use the empirical rule to solve.
A jar contains 38 red marbles numbered 1 to 38 and 38 blue marbles numbered 1 to 38 a marble is drawn at random from the jar
Answer:
[tex]P(Red) = 0.50[/tex]'
[tex]P(Odd) = 0.50\\[/tex]
Step-by-step explanation:
Given
[tex]Red = 38[/tex]
[tex]Blue = 38[/tex]
Required (Missing part of the question)
(a) The marble is red. (b) The marble is odd-numbered
Solving (a): Probability of Red.
This is calculated as:
[tex]P(Red) = \frac{Red}{Total}[/tex]
[tex]P(Red) = \frac{38}{38+38}[/tex]
[tex]P(Red) = \frac{38}{76}[/tex]
[tex]P(Red) = 0.50[/tex]
Solving (b): Probability of Odd
Since each marble type is numbered 1 to 38, then half of it are odd.
i.e. 19 odd numbered red marbles and 19 odd numbered blue marbles.
So, the probability of odd is:
[tex]P(Odd) = \frac{Odd}{Total}[/tex]
[tex]P(Odd) = \frac{19+19}{38+38}[/tex]
[tex]P(Odd) = \frac{38}{76}[/tex]
[tex]P(Odd) = 0.50\\[/tex]
The difference of two numbers is 2. Their sum is 12. What are the numbers?
Answer:
the numbers would be 5 and 7.
Step-by-step explanation:
"the difference of two numbers is 2."
7 - 5 = 2"their sum is 12."
7 + 5 = 12since the difference of 7 and 5 is 2 and the sum of 7 and 5 is 12, 5 and 7 are the numbers that fulfill the statement.

Step-by-step explanation:
Write the equation of the line perpendicular to the given line that contains P.
P(-6, -3) y=x-1
Answer:
y= -x-9 because you have to find the negative reciprocal of the slope of the original line and then use the point slope formula y-y1=m(x-x1) to find the perpendicular line
Solve the inequality 15t > 180
Answer:
t>12
Step-by-step explanation:
t>180/15
then divide 180 by 15
and you gey t>12
The value of the given inequality is t> 12
What is inequality?inequality, In mathematics, a statement of an order relationship-greater than, greater than or equal to, less than, or less than or equal to-between two relation,
We have,
15t>180
According to the question
15t>180
t>180/15
then divide 180 by 15
and you will get t>12
Hence, the value of this inequality is t>12

A digital music
2. service sells 12 songs
for $9.96. At this rate,
how many songs
can you purchase
for $4.15?
Answer:
You can buy 5 songs.
Step-by-step explanation:
First, you would divide 9 by 12 which is 0.83, assuming that each song costs 0.83 by itself you would just add 0.83 + 0.83 until you reach 4.15, the amount of times you added is the answer, which is 5 lolz
For each of the following situations, explain why the combinations rule or the permutations rule should be used. (a) Determine the number of different groups of 5 items that can be selected from 12 distinct items. Use the permutations rule, since the number of arrangements within each group is of interest. Use the combinations rule, since the number of arrangements within each group is of interest. Use the permutations rule, since only the items in the group is of concern.
Answer:
Use the combinations rule, since the number of arrangements within each group is of interest.
Step-by-step explanation:
Arrangments rule:
Number of items to be arranged is the same as the number of places.
Permutations formula:
Number of items to be arranged is different of the number of places, and the order in which the items are placed is important(AB and BA are different outcomes).
Combinations formula:
Number of items to be arranged is different of the number of places, and the order in which the items are placed is not important(AB and BA are the same outcomes).
In this question:
5 items from a set of 12. The order in which the items are chosen is not important(for example, a book and a pencil would be the same as a pencil and a book). So the combinations formula is used, and the correct option is given by:
Use the combinations rule, since the number of arrangements within each group is of interest.
Solve for the value of z.
Answer:
13°
Step-by-step explanation:
2z + 5° + 5z - 6° = 90° { being complementary angles }
7z = 90° + 1°
7z = 91°
z = 91° / 7
z = 13°
Hope it will help :)
Answer:
2z+5+5z-6=90(right angle)
7z=90+1
z=91/7=13 is your answer
