Obasi earns 150\%150%150, percent of his regular hourly wage while working overtime. What fraction of his regular hourly wage do
loris [4]

Answer:

3/2 or 1 1/2

Step-by-step explanation:

We are told that:

Obasi earns 150% of his regular hourly wage while working overtime

The fraction of his regular hourly wage that Obasi earns while working overtime is written as:

150%

= 150/100

= 15/10

= 3/2

= 1 1/2

The fraction of his regular hourly wage that Obasi earns while working overtime is 3/2 or 1 1/2

On an indoor circular track of circumference 50 feet, Joneal starts at point $S$, runs in a counterclockwise direction, and then
Archy [21]

Answer:

He stoped on 3th quarter,i.e, $C$.

Step-by-step explanation:

He ran 105 full circles ( 5280/50=105 ( rst= 30ft) ). So in the last circles he started from point S to run 30ft more.

The quarter of the circle is long 50ft/4= 12,5ft. So for 30 feets he must run 2 quarters, its 25ft. The last 5ft he ran on the 3th quarter, so he stoped on C.

This answer $C$, if $C$ is the 3th quadrant, i don't see the picture of the track.

Answer:

1/8 + 1/2 = 5/8

Step-by-step explanation:

Total number of beads = 8

Number of green beads = 4

Number of yellow beads = 1

Fraction of green beads :

Number of green / total number of bead = 4 / 8 = 1/2

Fraction of yellow beads :

Number of yellow / total number of bead = 1 / 8

Number of green or yellow bead :

1/8 + 1/2 = (1 + 4) / 8 = 5/8

According to the Center for Disease Control and Prevention (CDC), the mean life expectancy in 2015 for non‑Hispanic white males
wolverine [178]

Answer:

The 95% confidence interval for the mean life expectancy of non-hispanic white males is (73.3 years, 79.3 years).

Step-by-step explanation:

This is the 95% confidence interval for the mean life expectancy of non-hispanic white males.

Our sample size is 100

The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So

df = 100-1 = 99

Then, we need to subtract one by the confidence level \alpha and divide by 2. So:

\frac{1-0.95}{2} = \frac{0.05}{2} = 0.025

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 99 and 0.025 in the two-sided t-distribution table, we have T = 1.984

Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So

s = \frac{15}{\sqrt{100}} = 1.5

Now, we multiply T and s

M = T*s = 1.984*1.5 = 2.976

Then

The lower end of the confidence interval is the mean subtracted by M. So:

L = 76.3 - 2.976 = 73.3

The upper end of the confidence interval is the mean added to M. So:

L = 76.3 + 2.976 = 79.3

The 95% confidence interval for the mean life expectancy of non-hispanic white males is (73.3 years, 79.3 years).
