2+2+3+4+4+5+5+8+9+5800= ??????????????? divided by 6 times 34 bb

The sum of 5 times a number and minus −2, plus 7 times a number

Olenka [21]

Answer:

12x + 2

Step-by-step explanation:

Let the number be represented by x.

Then five times the number = 5*x

Seven times the number = 7*x

Sum of 5 times the number minus -2 = $5*x - (-2)$ = $5x +2$

Adding seven times the number to this expression yields, $5x+2+7x$

$= (5+7)x+2$

$= 12x+2$

So the simplified expression corresponds to 12x + 2.

You are studying the relationship between the history of early childhood trauma (categorized as trauma/no trauma) and weight in

jeka57 [31]

Answer:

You can decide to reject the Null Hypothesis at p < 0.05.

Step-by-step explanation:

In this case, the relationship between the history of early childhood trauma and weight in adulthood are being studied.

The categories of childhood trauma are:

Trauma and No trauma.

So, number of rows is, r = 2.

The categories of weight in adulthood are:

Low to normal, Overweight, and Obese

So, number of columns is, c = 3.

The distribution of the statistic $\chi^{2}$ is chi-square with (r - 1)(c - 1) degrees of freedom, where r represents the number of rows in the two-way table and c represents the number of columns.

Compute the degrees of freedom as follows:

$df = (r-1)(c-1)=(2-1) \times (3-1) = 2$

It is provided that the calculated value of Chi-square test statistic is 18.26.

Compute the p-value of the test as follows:

$p-value=P(\chi^{2}_{2}\geq 18.26)\\=0.000108\\\approx0.00011$

Decision rule:

The null hypothesis will be rejected if the p-value of the test is less than the significance level.

The significance level is, α = 0.05.

p-value = 0.00011 < α = 0.05.

The null hypothesis will be rejected at 5% level of significance.

Thus, the complete statement is:

"You can decide to reject the Null Hypothesis at p < 0.05."

Darcy bought 1 2 pound of cheese and 5 6 pound of hamburger for a barbecue. Use the numbers to compare the amounts of cheese and

Zepler [3.9K]

Answer:

Darcy bought more Hamburgers than Cheese
1/2 pound of cheese < 5/6 pounds of Hamburgers

Step-by-step explanation:

Darcy bought 1/2 pounds of cheese and 5/6 pounds of hamburgers.

Convert these to decimals to be sure which is larger:

= 1/2 = 5/6

= 0.5 pounds = 0.83 pounds

The hamburgers are therefore more so the comparison would look like:

1/2 pound of cheese < 5/6 pounds of hamburgers
