Answer by JKismyhusbandbae: So to find the pattern we can subtract 49 and 42 to get 7 which should be our pattern to double check add 49 plus 7 to get 56 so 56 plus 7 equals 63.

1. Betty collected 42 petition signatures on the first day, 49 on the second day, and 56 on the third day. If this pattern continues, how many signatures will she collect on the fourth day? Explain how you obtained your answer.

The pattern is getting 7 more signatures everyday.

56 + 7 = 63

I found this answer by finding the rule and adding it to the third day to get the total amount of signatures for the fourth day.

A recipe for casserole calls for 2 cups of rice. The recipe makes 6 servings of casserole. how many cups of rice will you need t

ss7ja [257]

You will need 3.333.... cups of rice to make 10 servings of casserole.

Explanation

The recipe which makes 6 servings of casserole, needs 2 cups of rice.

Suppose, you need $x$ cups of rice for making 10 servings of casserole.

Now, the equation according to the ratio of "cups of rice" to the "servings of casserole" will be.....

$\frac{x}{10}=\frac{2}{6}\\ \\ 6x= 2*10=20\\ \\ x=\frac{20}{6}=3.333.....$

So, you will need 3.333.... cups of rice to make 10 servings of casserole.

Ephemeral services corporation (esco) knows that nine other companies besides esco are bidding for a $900,000 government contrac

EastWind [94]

Answer:

c. $100,000

Step-by-step explanation:

Calculation of the expected net profit of Ephemeral services corporation

Since we are been told that 9 other companies besides esco are as well bidding for the $900,000 government contract, it means we have to find the expected net profit by dividing 1 by 9×$900,000 .Thus ESCO can only expect to cover its sunk cost.

Hence ,

E(X) = (1/9) × $900,000

E(X)=0.111111111×$900,000

E(X)= $100,000

Therefore the expected net profit would be $100,000

Given f(x)=x^2+12x+26 .

lapo4ka [179]

f(x)=x^2+12x+26

Vertex form of f(x) = a(x-h)^2 +k

We change f(x) into vertex form using completing the square method

$f(x)=x^2+12x+26$

We take half of square of middle term

middle term is 12

Half of square of 12 is $\frac{12}{2}=6$ then 6^2 = 36

Add and subtract 36 to complete the square

$f(x)=(x^2+12x+36)+26-36$

$f(x)= (x+6)^2 +26 - 36 f(x)= (x+6)^2 -10$

The vertex form $f(x)= (x+6)^2 -10$

The following are the hypotheses for a test of the claim that college graduation statue and cola preference are independent. H0:

Shkiper50 [21]

Answer:

$\chi^2 = 0.579$

And the critical value for the significance level used is:

$\chi^2_{crit}= 5.991$

Since the calculated value is less than the critical value we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the College graduation status and cola preference are independent

Step-by-step explanation:

For this case we want to test the following hypothesis:

Null hypothesis: College graduation status and cola preference are independent

Alternative hypothesis: College graduation status and cola preference are dependent

For this case we got a calculated statistic of:

$\chi^2 = 0.579$

And the critical value for the significance level used is:

$\chi^2_{crit}= 5.991$
