Answer:

195 minutes

Step-by-step explanation:

1 hour = 60 minutes

3 hours = 3 × 60 = 180 minutes

one quarter of an hour = $\frac{1}{4}$ × 60 = 15 minutes

3 $\frac{1}{4}$ hours = 180 + 15 = 195 minutes

Answer:

195 minutes

Step-by-step explanation:

.5 x 60 = 30

.5 x 30 = 15

.25 x 60 = 15

180 + 15 = 195

Answer:

-2 = x/4 + 1

Subtract 1 from both sides:

-2 - 1 = x/4 + 1 - 1

-3 = x/4

Multiply both sides by 4:

-3 * 4 = x/4 * 4

-12 = x

3x+5

X= 12 or 18

This could be read two different ways.

0=2/3x-12

12=2/3x

12÷2/3=x

12*3/2=x

18=x

—-OR—-

0=2/3(x-12)

0=2/3x-8

8=2/3x

8÷2/3=x

8*3/2=x

12=x

Answer:

We don't have sufficient evidence to support the claim

Step-by-step explanation:

Null hypothesis:

$H_0: p = 0.276$

Alternate hypothesis:

$H_1: p < 0.276$

The P-value is 0.3064

0.3064 probability of finding a sample proportion lower than the one found.

The p-value is higher than the significance level of 0.05, which means that there is no sufficient evidence to support the claim.

Answer:

$1,800(1.015)^{x}$

Step-by-step explanation:

we have

$f(x)=1,000(1.015)^{x}$

$g(x)=800(1.015)^{x}$

we know that

To find the function that represent the total amount Jack and Suzie will save in x years, adds f(x) and g(x)

$f(x)+g(x)=1,000(1.015)^{x}+800(1.015)^{x}$

$f(x)+g(x)=[1,000+800](1.015)^{x}$

$f(x)+g(x)=1,800(1.015)^{x}$
