Answer:

q = 2/3

Step-by-step explanation:

From the question the equation is given by,

1/2 - 1/8q=q-1/4

Rearranging the terms in the given equation and bringing the similar terms to the same side of the equation,

- 1/8q -q = -1/4 - 1/2

Adding the terms in the equation of both left and right hand side of equation:

-((1+8)/8) × q = -(1+2)/4

-(9/8) × q = -3/4

Dividing the both sides of the equation by 3/4

-3/2q = -1

Multiplying the both sides of the equation by -2/3

Therefore, q=2/3

Answer:

Susan has more books than Michael.

Step-by-step explanation:

If Susan has 50% more books and Michael has 40 books, that means Susan has 1.5 times 40 = 60

40 + 8 = 48

60 is more than 48, so Susan has more books than Michael

Answer:

y=500x+100

Step-by-step explanation:

y=mx+b is slope-intercept form where m is the slope and b is the y-intercept.

Fara has to pay $100 to set the tent up, so b is 100.

Fara has to pay $500 per hour, so m is 500.

So, the equation is y=500x+100

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 402 gram setting. It is

lidiya [134]

Answer:

The value of t test statistics is -2.25.

Step-by-step explanation:

We are given that a manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 402 gram setting. It is believed that the machine is under filling the bags.

A 25 bag sample had a mean of 393 grams with a standard deviation of 20.

Let $\mu$ = mean filling of bags by the machine.

So, Null Hypothesis, $H_0$ : $\mu \geq$ 402 gram {means that the the machine is not under filling the bags}

Alternate Hypothesis, $H_A$ : $\mu$ < 402 gram {means that the the machine is under filling the bags}

The test statistics that would be used here One-sample t test statistics as we don't know about the population standard deviation;

T.S. = $\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }$ ~ $t_n_-_1$

where, $\bar X$ = sample mean bag filling = 393 grams

s = sample standard deviation = 20 grams

n = sample of bags = 25

So, test statistics = $\frac{393-402}{\frac{20}{\sqrt{25} } }$ ~ $t_2_4$

= -2.25

The value of t test statistics is -2.25.
