An engineer wants to know if the average amount of energy used in his factory per day has changed since last year. The factory u

Answer:

<em> The calculated value Z = 1.8823 <1.96 at 0.05 level of significance</em>

<em> The average amount of energy used in his factory per day has changed since last year. </em>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that mean of the Population = 2000 (MWH)

Given that size of the sample 'n' = 400

Given that mean of sample x⁻ = 2040 MWH

Given that the standard deviation = 425 MWH per day

<u><em>Step(ii):-</em></u>

<u><em>Null hypothesis:H₀: μ = 2000 (MWH)</em></u>

<u><em>Alternative Hypothesis:H₁: μ≠ 2000( MWH)</em></u>

<em>Test statistic</em>

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

<em> </em> $Z = \frac{2040-2000}{\frac{425}{\sqrt{400} } }$ <em></em>

<em> Z = 1.8823</em>

<em>The calculated value Z = 1.8823 <1.96 at 0.05 level of significance</em>

<u><em>Final answer:</em></u><em>-</em>

<em> The calculated value Z = 1.8823 <1.96 at 0.05 level of significance</em>

<em> The average amount of energy used in his factory per day has changed since last year. </em>

Janie and Jasmine are playing three games at an arcade. Each of the games requires either 2, 3, or 4 tokens. The girls plan to p

Brrunno [24]

Answer:

m+2n+2p=16 tokens or m+2(n+p)= 16 tokens

Step-by-step explanation:

First, we must understand how many tokens they have.

Janie played the 3-token game four times, so she used 12 tokens (3n x 4 = 12). Jasmine played the 4-token game five times, so she used 20 tokens (4p x 5 = 20).

Added up, the girls have 32 tokens (12+20 = 32 tokens (t)).

In order to play a round of the three games, 9 tokens are required (m+n+p = 9 / 2+3+4 = 9) by each girl. (32t-18t=14) 14 tokens are left after taking a ride in every game each. 14 left divided by 2 will leave 7 more tokens for each girl. You can split these 7 tokens into an n+p = 7 tokens

Thus,

Each girl can ride as follows:

m+2n+2p=16 tokens or m+2(n+p)= 16 tokens
