E. 4 shifts

Step-by-step explanation:

L.C.M. of 18 and 24

18=2×3×3

24=2×2×2×3

L.C.M.=2×2×2×3×3=72

so after 72 hours time will be same

or 72/18=4 shifts

A group of friends went fishing. They each caught 20 fish but not all of them were keepers. Which person was able to keep 3/5 of

Romashka-Z-Leto [24]

Answer:

Those who were able to keep 12 fishes

Step-by-step explanation:

Given

Total = 20 (each)

Required

Which was able to keep 3/5

First, we need to calculate 3/5 of the total number of fishes

Fish = 3/5 * 20

Fish = (3 * 20)/5

Fish = 60/5

Fish = 12

From the calculation above, only those who keep 12 of the 20 fishes were able to keep 3/5 of their fishes

Question 6 (1.25 points)

Lisa [10]

Answer:

Test statistic Z= 1.713

The calculated Z- value = 1.7130 < 2.576 at 0.01 level of significance

Null hypothesis is accepted

There is no difference between the mean annual salary of all lawyers in a city is different from $110,000

Step-by-step explanation:

Step(i):-

A researcher wants to test if the mean annual salary of all lawyers in a city is

different from $110,000

Mean of the Population μ = $110,000

Sample size 'n' = 53

Mean of the sample x⁻ = $114,000.

standard deviation of the Population = $17,000,

Level of significance = 0.01

Null hypothesis :

There is no difference between the mean annual salary of all lawyers in a city is different from $110,000

H₀: x⁻ = μ

Alternative Hypothesis : x⁻ ≠ μ

Step(ii):-

Test statistic

$Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{114000-110000}{\frac{17000}{\sqrt{53} } }$

Z = 1.7130

Tabulated value Z = 2.576 at 0.01 level of significance

The calculated Z- value = 1.7130 < 2.576 at 0.01 level of significance

Null hypothesis is accepted

There is no difference between the mean annual salary of all lawyers in a city is different from $110,000

75 is 128% of what number

Oksana_A [137]

$\bold \pink{let \: the \: number \: be \: x}$

$\mathsf{128\% \times x = 75}$

$\\ \\ \frac{128}{100} \times x = 75 \\ \\ x = \frac{75}{1} \times \frac{100}{128} \\ \\ x = \frac{7500}{128}$

$\boxed{x = 58.59375}$

75 is 128% of 58.59375
