For this problem, we will take the given information and use it to create an expression representing the problem. We want the expression to equal the amount Dylan has.

Let's start by defining a variable.
d=dollars Leo has

We know that Dylan has 3 more dollars than twice the amount Leo has. We can take this information and create our expression.

2d+3 is our expression.

We multiply our variable by 2 and then add 3 since Dylan has twice the amount Leo has plus an addition of 3 more dollars.

Therefore, the solution is 2d+3.

ss7ja [257]

Answer:

C. Fail to Reject H0.

Step-by-step explanation:

If the P-value is 0.06, that means that the result enters in the acceptance region. It is a value that is expected to happen if both proportions are equal (null hypothesis) at this significance level.

The conclusion when the P-value is bigger than the significance level is that the effect is not significant and it failed to reject the null hypothesis.

A machine can grade 30 tests in 2 minutes. At this rate, how long will it take the machine to grade 135 tests?
Nonamiya [84]

Answer:

9 minutes

Step-by-step explanation:

(2 min(60 s/min)) / 30 test = 4 s/test

135 test(4 s/test) = 540 s

540s / 60 s/min = 9 min

The functions $f$ and $g$ are defined as follows: \[f(x) = \sqrt{\dfrac{x+1}{x-1}}\quad\text{and}\quad g(x) = \dfrac{\sqrt{x+1}}
CaHeK987 [17]

Answer:

The answer is "domain and range are different".

Step-by-step explanation:

Given:

f(x) = \sqrt{\frac{x+1}{x-1}}\\\\g(x) =\frac{\sqrt{x+1}}{\sqrt{x-1}}\\

Solve f(x) to find domain and range:

for element x: R:

⇒ x \leq -1 \ \ \ and \  \ \  x > 1 range:

for  \ \ f(x) \times element : 0 \leq f(x)< 1 \ \ \ or \ \ f(x)>1

g(x) =\frac{\sqrt{x+1}}{\sqrt{x-1}}\\

Solve for domain:

⇒ \ when \ x \ element \ R: \ \ \ x>1  

Solve for range:  

⇒ g(x) \times element  R : g(x)>1

So, the value of the method f(x) and g(x) (range and domain) were different.

Find the value of x if a, b, and c are collinear points and b is between a and c. ab=x,bc=x 2,ac=14
Aleks04 [339]

The value of x is 7 for the given collinear points a, b, and c as b is the mid-point of ac.

According to the given question.

a, b, and c are collinear points. Which means all points a, b, and c lie in a same plane.

b is lies between a and c.

Also,

ab = x, bc = x and ac = 24.

Since, b lies in between a and c, and it is given that ab = x and bc = x.

Which means b is the mid point of ac.

Therefore,

ab + bc = ac

Substitute the values of ab, bc and ac in the above equation.

⇒ x + x = 14

⇒ 2x = 14

⇒ c = 14/2

⇒ c = 7

Therefore, the value of x is 7.
