A bowl holds 3/10 cup of oil when it is 2/5 full. Which statement best describes the quotient of 3/10 divided by 2/5?

muminat

If 3/10 cup is 2/5 full, then the bowl holds:

(3/10) / (2/5)

(3/10)/(2/5) = 3/10 * 5/2 = 15/20 = 3/4

The bowl holds 3/4 of a cup

Heather is a student in a class that has been asked to conduct a hypothesis test for a population proportion. The null and alter

Rasek [7]

Answer:

Alan = reject H0

Bill = cannot say

Step-by-step explanation:

Given that Heather is a student in a class that has been asked to conduct a hypothesis test for a population proportion.

$H0: p = 0.5 \\Ha: p ≠ 0.5$

(two tailed test at 5% significance level)

Since she rejects null hypothesis p value should have been less than 0.05

when p value <0.05, it is definitely less than 0.10

So at 1% level of significance also the null hypothesis would be rejected.

So Alan also would get the same result as to reject the H0

But about Bill since Bill uses 0.01, we cannot definitely say that p value is less than or greater than 0.01

All we know is that p is less than 0.05

Hence it is impossible to tell from the information for Bill

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!

Hello and Good Morning/Afternoon

Let's take this problem step-by-step:

To find the solution to a system of equation

⇒ must set the equations equal to each other

⇒ and solve

Let's put that into action

$x^2-2x+3 = -2x + 12\\x^2-2x+2x+3-12=0\\x^2-9=0\\(x+3)(x-3)=0$

At this point, to make the whole thing equal zero

⇒ either 'x+3' or 'x-3' equals zero

⇒ must find 'x' that satisify either equation

$x-3=0\\x=3\\\\x+3=0\\x=-3$

Let's find the corresponding f(x) to each x-value

$f(3) = -2(3)+12=-6+12 = 6\\\\f(-3) = -2(-3) + 12=6+12=18$

Therefore the solutions are (3,6) and (-3,18)

Answer: (3,6), (-3,18)

Hope that helps!

In the following table of values, the first differences are

ExtremeBDS [4]

Answer:

-7

Step-by-step explanation:

Given

$\begin{array}{ccc}x & {y} & {First\ difference} & {-2} & {34} & {}&{-1} & {27} & {} &{0} & {20} & {} & {1} & {13} & {} & {2} & {6} &{} \ \end{array}$

Required

The first difference

To do this, we simply calculate the difference between the consecutive y-values.

i.e.

$d = y_{n+1} - y_n$

So, we have:

$d = y_2 - y_1 = 27 - 34 = -7$

$d = y_3 - y_2 = 20 - 27 = -7$

$d = y_4 - y_3 = 13 - 20 = -7$

$d = y_5 - y_4 = 6-13 = -7$

Hence, the first differences are -7 (all through)
