When we add/subtract fractions, why do we need denominators?

15 times the square of a nonzero number is equal to 20 times the number

melisa1 [442]

Answer:

Let the number be x

The expression above is written as

15x² = 20x

Divide both sides by x

We get

15x²/x = 20x/x

15x = 20

Divide both sides by 15

x = 20/15

x = 4/3

In line 17, "summons" most nearly means

erica [24]

In line 17, "summons" most nearly means calls forth.

"Summon(s)" generally means to call something or someone.
Here, when the writer says "the hubbub summons sense-memories" it means that the hubbub brings to the forefront of his mind the sense-memories.
Thus we can conclude that 'summons' best means 'call forth' in the given context. Thus B is the best answer.

What happens when you get summoned?

A Summons is an invitation to come to court. In some cases, the court will schedule a call or a video call for the first appearance instead.
In other cases, the court will ask that you file an appearance or an answer. Your Summons should say so.

Can summons be Cancelled?

Yes, the summons can be cancelled or quashed as appropriately required by law dependent on the facts of settlement and the terms and conditions determined therein between the parties.
The legal procedure has to be followed for the same.

A random sample of 10 parking meters in a resort community showed the following incomes for a day. Assume the incomes are normal

GenaCL600 [577]

Answer:

A 95% confidence interval for the true mean is [$3.39, $6.01].

Step-by-step explanation:

We are given that a random sample of 10 parking meters in a resort community showed the following incomes for a day;

Incomes (X): $3.60, $4.50, $2.80, $6.30, $2.60, $5.20, $6.75, $4.25, $8.00, $3.00.

Firstly, the pivotal quantity for finding the confidence interval for the population mean is given by;

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

where, $\bar X$ = sample mean income = $\frac{\sum X}{n}$ = $4.70

s = sample standard deviation = $\sqrt{\frac{\sum (X-\bar X)^{2} }{n-1} }$ = $1.83

n = sample of parking meters = 10

$\mu$ = population mean

Here for constructing a 95% confidence interval we have used a One-sample t-test statistics because we don't know about population standard deviation.

So, 95% confidence interval for the population mean, $\mu$ is ;

P(-2.262 < $t_9$ < 2.262) = 0.95 {As the critical value of t at 9 degrees of
