Answer:

Halle bought 6 plums from the store.

Step-by-step explanation:

Given:

total cost of the peaches = $1.88

Cost of 1 Plum = $0.33

Total Money paid = $3.86

We need to find the number of Plums.

Let the number of plums be x.

Now we know that Total money paid is equal to Cost of peaches plus Cost of each Plum multiplied with number of plums.

Hence the expression can be framed as;

1.88+0.33x=3.86

Now Solving the above expression to find the value of x;

1.88+0.33x=3.86\\0.33x = 3.86-1.88\\0.33x=1.98\\\\x = \frac{1.98}{0.33} = 6

Hence Halle bought 6 plums from the store.

The correlation coefficient for the ages of drivers in a driver safety class and the number of traffic violations they have rece
Doss [256]
A correlation coefficient is always a value in between -1 and 1
The closest a coefficient to -1, the correlation is a strong negative correlation
The closest a coefficient to 1, the correlation is a strong positive correlation
The closest a coefficient to 0, there is no correlation at all

The coefficient -0.61 shows a strong negative correlation
This means that the relationship between the age and the violation is an inverse relationship; as age increases, violation decreases

LekaFEV [45]

Answer:

  • 4 months

Step-by-step explanation:

Let the number of months be x

Alligator 1 weight = 4 + 2x

Alligator 2 weight = 8 + x

  • 4 + 2x = 8 + x
  • 2x - x = 8 - 4
  • x = 4

The answer is 4 months

Answer:

5<em>i</em>

Step-by-step explanation:

  1. = \sqrt{-1 * 25}
  2. = \sqrt{-1}\sqrt{25}
  3. = \sqrt{-1} * 5

Rule: \sqrt{-1} = <em>i</em>

So you get <em>i  </em>* 5<em> </em>=<em> </em>5<em>i</em>

The p-value for a one-sided test of the population proportion is 0.0513. Which of
uysha [10]

Using the equation of the test statistic, it is found that with an increased sample size, the test statistic would decrease and the p-value would increase.

<h3>How to find the p-value of a test?</h3>

It depends on the test statistic z, as follows.

  • For a left-tailed test, it is the area under the normal curve to the left of z, which is the <u>p-value of z</u>.
  • For a right-tailed test, it is the area under the normal curve to the right of z, which is <u>1 subtracted by the p-value of z</u>.
  • For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is <u>2 multiplied by 1 subtracted by the p-value of z</u>.

In all cases, a higher test statistic leads to a lower p-value, and vice-versa.

<h3>What is the equation for the test statistic?</h3>

The equation is given by:

t = \frac{\overline{X} - \mu}{\frac{s}{\sqrt{n}}}

The parameters are:

  • \overline{X} is the sample mean.
  • \mu is the tested value.
  • s is the standard deviation.
  • n is the sample size.

From this, it is taken that if the sample size was increased with all other parameters remaining the same, the test statistic would decrease,  and the p-value would increase.
