Ussed = x 
biked = 75 + x 

total trip = 325 = x + (75 + x) 
325 = 75 + 2x 
250 = 2x 
x = 125 

<span>biked = 75 + x = 75 + 125 = 200 km</span>

ussed = x

biked = 75 + x


total trip = 325 = x + (75 + x)

325 = 75 + 2x

250 = 2x

x = 125


biked = 75 + x = 75 + 125 = 200 km

Vinil7 [7]

Answer:

Now we have everything in order to replace into formula (1):

18-2.262\frac{2.75}{\sqrt{10}}=16.03    

18+2.262\frac{2.75}{\sqrt{10}}=19.97    

Step-by-step explanation:

Information given

\bar X=18 represent the sample mean

\mu population mean (variable of interest)

s=2.75 represent the sample standard deviation

n=10 represent the sample size  

Confidence interval

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

The degrees of freedom are given by:

df=n-1=10-1=9

The Confidence is 0.90 or 90%, the significance is \alpha=0.1 and \alpha/2 =0.05, and the critical vaue would be t_{\alpha/2}=2.262

Now we have everything in order to replace into formula (1):

18-2.262\frac{2.75}{\sqrt{10}}=16.03    

18+2.262\frac{2.75}{\sqrt{10}}=19.97

One increased by 7 times a number is the same as 5 times the number plus 25
sammy [17]

Answer:

12

Step-by-step explanation:

Let the number = x

7x + 1 = 5x + 25                 Subtract 5x from both sides.

7x - 5x + 1 = 5x - 5x + 25   Combine

2x + 1 = 25                          Subtract 1 from both sides.

2x + 1 - 1 = 25-1                   Combine

2x = 24                               Divide by 2

2x/2 = 24/2

x = 12

Marine biologists have been studying the effects of acidification of the oceans on weights of male baluga whales in the Arctic O
PSYCHO15rus [73]

Answer:

c. 61.25 kg

Step-by-step explanation:

The margin of error in estimating the true mean weight of male baluga whales in the Artic Ocean.

a. 15.31 kg

b. 51.40 kg

c. 61.25 kg

d. 80.49 kg

Margin of Error Formula= z × Standard deviation/√n

95% confidence interval = 1.96

Standard deviation = 125kg

n = 16 samples

Margin of error= 1.96 × 125/√16

= 1.96 × 125/4

= 245/4

= 61.25kg

The margin of error in estimating the true mean weight of male baluga whales in the Artic Ocean is 61.25kg
