A manufacturer knows that their items have a normally distributed length, with a mean of 16.2 inches, and standard deviation of 0.9 inches. If one item is chosen at random, what is the probability that it is less than 16.4 inches long
Answer:
57.926%
Step-by-step explanation:
Calculation for the probability that it is less than
16.4 inches long
Using this formula
z = (X - μ) / σ
Where,
X represent Date=16.4
μ represent Mean=16.2
σ represent Standard deviation=0.9 inches
Let plug in the formula
z = (16.4 - 16.2) /0.9 inches
z=0.2/0.9 inches
z = 0.2
Using Z-score table to find the area of 0.2
z=0.57926*100
z=57.926%
Therefore the probability that it is less than
16.4 inches long is 57.926%

B. 1,500 miles per 50 hours
C. 800 miles per 16 hours
D. 900 miles per 20 hours
Answer:
C. 800 miles per 16 hours
Step-by-step explanation:
600 ÷ 15 = 40
1500 ÷ 50 = 30
800 ÷ 16 = 50
900 ÷ 20 = 45
40 > 30 < 50 > 45

2. Riverside Elementary School is holding a school-wide election to choose a school color. Five-eighths of the votes were for blue, 5/9 of the remaining votes were for green, and the remaining 48 votes were for red.
a. How many votes were for blue?
b. How many votes were for green?
Answer:
a. 180 votes were for blue
b. 60 votes were for green
Step-by-step explanation:
Fractions
It's known 5/8 of the votes of a school-wide election were for painting the school blue. Suppose there were x voters in school.
Since 5/8 were for blue, then
[tex]1-\frac{5}{8}=\frac{3}{8}[/tex]
Were for the rest of the colors. It's also known 5/9 of the remaining votes were for green, thus
[tex]1-\frac{5}{9}=\frac{4}{9}[/tex]
of the remaining votes were for red.
The votes for red are:
[tex]\frac{3}{8}\cdot\frac{4}{9}=\frac{1}{6}[/tex]
of the total voters.
We know these were 48 votes, thus
[tex]\displaystyle x=\frac{48}{\frac{1}{6}}[/tex]
[tex]x = 288[/tex]
There were 288 voters in school.
a. 5/8 were for blue, that is:
[tex]\frac{5}{8}*288=180[/tex]
180 votes were for blue
b. 288-180 = 108 votes were for others than blue, and 5/9 of them were for green:
[tex]\frac{5}{9}*108=60[/tex]
60 votes were for green and 108-60=48 votes were for red (as expected)
Pete plans to put silver Colored ribbon around a circular logo. About how many inches of silver colored ribbon will he need?
To determine the length of silver colored ribbon that Pete will need to put around a circular logo, we need to calculate the circumference of the logo.
The circumference of a circle can be found using the formula C = πd, where C represents the circumference and d represents the diameter of the circle. However, we are not given the diameter of the logo, so we cannot determine the exact length of the ribbon needed.
Assuming Pete knows the diameter or radius of the logo, he can calculate the circumference using the formula mentioned above. Once the circumference is determined, Pete will know how many inches of silver colored ribbon he will need. It is important to ensure that Pete has a little extra ribbon in case of any measurement errors or mistakes during the ribbon placement.

6. What is the y-value to the solution of
y = 5x -4
y = 2x + 8?
Answer:
y = 16, don't know if I'm 100% right but hope this helps.
Step-by-step explanation:
since they both equal Y they may be equal to each other
Then you would subtract 2x from both sides canceling it out on one side
2x + 8 = 5x - 4
-2x -2x
This would make the equation 8 = 3x - 4
next you add the 4 from both sides
8 = 3x - 4
+4 +4
This will leave you with 12 = 3x
now you divide 3 from both sides and 12/3 = 4 makes X = 4
next you take (4) and plug it in to one of the equations
y = 2(4) + 8
y = 8 + 8
y = 16

Polynomial long division is done using the same methods as for numerical long division. Each quotient term is multiplied by the divisor, and that product subtracted from the dividend to get the new dividend. You are done when the degree of the dividend is less than the degree of the divisor.
As with numbers, 0 is put where a placeholder is needed. Here, that is needed for the (missing) x^2 term in the dividend.
As with numbers, the remainder is expressed as a fraction using the divisor as the denominator.
The full quotient is 4x^2 +2x +11/4 +37/(8x-4).
