Answer:
16.5
Step-by-step explanation:
Find the value represented by a z-score of 2.403, given µ=63 and σ=4.25. Round your answer to one decimal place.
The z score formula =
z = (x-μ)/σ, where
x is the raw score = ?
μ is the population mean = 63
σ is the population standard deviation = 4.25
z = 2.403
Hence,
2.403 = (x - 63)/4.25
Cross Multiply
2.403 × 4.25 = x - 6.3
10.21275 = x - 6.3
Collect like terms
10.21275 + 6.3 = x
x = 16.51275
Approximately to 1 decimal place the value = 16.5

Answer:
30 square units
Step-by-step explanation:
We know that the area of a triangle is equal to half of the product between the base and the height.
In this case, we can see that one of the sides of the triangle is parallel to the x-axis, then we can define:
Base = difference between the two extreme x-values
In this case, the extremes (the point at the left and the point and the right) are:
(-5, 3) and (7, 3)
The difference between the x-values is:
D = (7 - (-5)) = 7 + 5 = 12
Then the base is 12 units long.
For the height, we can find the difference in the y-value between the lowest point and the highest one.
In this case, we have two points at the same height (both with y-value = 3)
and the top point is (4, 8)
The difference in the y-value is:
D = (8 - 3) = 5
Then the height is 5 units.
Now that we know the height and the base of the triangle, the area is:
A = (5 units)*(12 units)/2 = 30 square units.

Solve the equation. 8(x + 6) = 43 What is the value of x?
Answer:
Exact form
5/8
Decimal form
0.625
Step-by-step explanation:
Answer:
-5/8 or -0.625
Step-by-step explanation:
divide both sides by 8
[tex]\frac{8(x+6)}{8} =\frac{43}{8}[/tex]
Simplify
[tex]x+6 = \frac{43}{8}[/tex]
Subtract 6 from both sides
[tex]x+6 - 6 = \frac{43}{8} -6[/tex]
Convert the fraction to decimal and simplify
[tex]5.375 - 6 = -0.625[/tex]
Simplified:
[tex]-\frac{5}{8}[/tex]

Answer:
Step-by-step explanation:
C is correct. Comparing the given g(x) = (x - 2)^2 + 1 to
y = (x - h)^2 + k (h, k) is the vertex
we see that h = 2 and k = 1. This is the location of the vertex in equation C.
Tracy is filling the box with unit cubes that are 1 inch on each side. She will fill the box with cubes without any gaps or overlaps. What is the volume of the box?
Answer:
[tex]Volume = 48in^3[/tex]
Step-by-step explanation:
Given
See attachment for box
Required
The volume of the box
The number of boxes in each direction represents the length of that dimension.
So, from the attachment
[tex]Width = 4in[/tex]
[tex]Length = 3in[/tex]
[tex]Height = 4in[/tex]
The volume is:
[tex]Volume = Length * Width * Height[/tex]
[tex]Volume = 4in * 3in * 4in[/tex]
[tex]Volume = 48in^3[/tex]

Gas sells at a rate of 4 gallons for
$8.40. How much will it cost to fill
a tank holding 16 gallons?
Step-by-step explanation:
it will cost $33.60 to fill a tank holding 16 gallons.
Answer:
$33.60
Step-by-step explanation:
Unit rate per gallon is $2.10 (find this by dividing the cost by the number of gallons)
Multiply this number by 16
2.10*16 = $33.60
The muffin batter contains 2 cups of flour, 1 cup of milk, one half cup of sugar, and 3 eggs. What is the ratio of flour to milk?
Answer: 2 : 1
Step-by-step explanation:
The batter calls for 2 cups of flour and 1 cup of milk.
That means that for every 2 cups of flour, the muffin batter would need 1 cup of milk.
Ratio of flour to milk will therefore be:
= Amount of flour needed : Amount of milk needed
= 2 cups of flour : 1 cup of milk
= 2 : 1
Find the unit rate.

A box contains 6 black socks and 4 red socks. What is the probability of picking two black socks from the bag without replacement? What is the answer in simplest form?
Answer:
9/25
Step-by-step explanation:
Our box contains 10 socks. (6, which are black and 4 which are red)
Probability of picking 1 black sock will be 6/10
Number of ways it can occur / Total number of outcomes.
In this question we pick two socks, one black firstly and another black, in the second turn. When we say AND, it means intersection
P (B₁ ∩ B₂) = 6/10 . 6/10
When the events are independent, the probability of the intersection will be the product of the probabilities,
P (B₁ ∩ B₂) = 36/100 = 9/25

Find the area of the circle. Round your answer to the nearest hundredth.
Answer:
176.63 cubic in. =A
Step-by-step explanation:
The area of a circle can be found by using the equation [tex]\pi r^{2}[/tex]=A. The problem gives us the diameter, but we need the radius. To find the radius divide the diameter by 2, so raduis= 7.5 in.
[tex]\pi r^{2}[/tex]=A
(3.14)([tex]7.5^{2}[/tex])=A
(3.14)(56.25)=A
176.63 cubic in. =A
