Easy, 100 x 3 is 300 pounds, 5 x 3 is 15, so 15 pounds. :)

15 pounds because 5 x 3 equals 15.

Answer:

a = 1

b = 3

c = 1

d = 2

e = 6

f = 8

Step-by-step explanation:

Any integer with power as zero = 1

2^x

2^0

= 1

3 * 2^x

3 * 2^0

3 * 1

= 3

2 ^ 3(x)

2 ^ 3(0)

2 ^ 0

= 1

2^1

= 2

3 * 2^x

3 * 2^1

3 * 2

= 6

2 ^ 3(x)

2 ^ 3(1)

2 ^ 3

2 * 2 * 2

= 8

Can u plz help me?...

Westkost [7]

Answer:

a 4 1/5

b 7 7/24

Step-by-step explanation:

a 7/9 * 5 2/5

Change the mixed number to an improper fraction

7/9 * (5*5+2)/5

7/9 * 27/5

Rewrite

7/5 * 27/9

7/5 * 3

21/5

Change this back to a mixed number

5 goes into 21 4 times (4*5 = 20 ) with 1 left over

4 1/5

b 1 3/4 * 4 1/6

Change to improper fractions

(4*1+3)/4 * (6*4+1)/6

7/4 * 25/6

175/24

Change back to a mixed number

24 goes into 175 7 times (7*24 =168 ) with 7 left over

7 7/24

An automobile manufacturer has given its van a 47.2 miles/gallon (MPG) rating. An independent testing firm has been contracted t

7nadin3 [17]

Answer:

The test statistics is $t = -1.7$

The Null and Alternative hypothesis are

$H_o : \mu = 47.2$ and $H_a : \mu \ne 47.2$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 47.2 miles/gallon(MPG)$

The sample size is $n = 250 \ van$

The sample mean is $\= x = 47.0$

The sample standard deviation is $\sigma = 1.9$

The level of significance is $\alpha = 0.02$

Given that the value which the manufacturer gave the automobile is 47.2 and it is believed that this is not correct, then

The Null Hypothesis is

$H_o : \mu = 47.2$

The alternative Hypothesis is

$H_a : \mu \ne 47.2$

The test statistics can be mathematically evaluated as

$t = \frac{\= x- \mu}{\frac{\sigma }{\sqrt{n} } }$

substituting values

$t = \frac{\= 47- 47.2}{\frac{1.9 }{\sqrt{250} } }$

$t = -1.7$
