Question #8

Answers

Answer 1

Answer:

B. m<B=50

C. m<C=65

Step-by-step explanation:

We know that the interior angles of a triangle add up to 180 so knowing that A and C would be the same because of the fact it’s isosceles, the measure of A+C=130 meaning measure of missing angle B would be 50.

2400 people attended a football game. 1728 of the people attending supported the home team, while 672 supported the visiting team. What percentage of people attending supported the home team?

Answers

Answer:

Percentage= 72%

Step-by-step explanation:

Giving the following information:

Total population= 2,400

People supporting the local team= 1,728

To calculate the percentage of people supporting the local team, we need to use the following formula:

Percentage= (people supporting / total population)*100

Percentage= (1,728/2,400)*100

Percentage= 72%

Using the algebraic expression 4n + 6, what is the greatest whole-number value that will give you a result less than 100?

Answers

Answer:

Step-by-step explanation:

Allow 4n+6=100

∴4n=94

∴n=23.5

If 23.5 gives you 100 exactly, the greatest whole number that'll give you a result less than 100 is 23.

An object is moving at a speed of 230 feet per week. Express this speed in inches per
minute. Round your answer to the nearest hundredth.

Answers

Answer:

Step-by-step explanation:

0.27 inches per minute....

An object is moving at a speed of 230 feet per week. This speed in inches per minute will be 0.27.

We know ,

1 feet = 12 inches and

1 week= 7days = 24×7 hours = 24×7×60 min.

= 10080 min.

Now, we just need to be careful with our multiplication and division. So we are going to have 230 times 12 on top divided by 24 times 7 times 60 i.e., 10,080 on bottom.

230 feet per week in inches per min = 230×12/10,080.

After evaluating and rounding up to 2 decimal places or the hundredth place , we will get our answer i.e., 0.27 inches/min.

Answers

Answer:

$6617

Step-by-step explanation:

Use the formula for calculating compound interest A=P0ert where A is the unknown, P0=4400, r=0.034, and t=12. Substitute the values into the formula and simplify.

A=4400e0.034⋅12

A=4400e0.408

A=4400(1.503...)

A=6616.75

After 12 years, there will be A≈6617 in the account, rounded to the nearest dollar.

The claim is that the standard deviation of the speeds of drivers in Bradford is 8 mph. An experienced driver feels that this is very low. If a random speed check is conducted for 50 drivers, the standard deviation is 10.5 mph. Can we reject the null at

Answers

Answer:

Null hypothesis is rejected. Standard deviation is > 8 miles per hour

Step-by-step explanation:

σ [Population standard deviation] = 8 , s [sample standard deviation] = s

n [no of items] = 8

H0 [Null] : σ = 8 ; H1 [Alternate - Right Tail] : σ > 8

χ2 = (n - 1) . s^2 / σ^2

= 49 x (10.5)^2 / 82 = 5402.25 / 64

χ2 = 84.410

df [degree of freedom] = n -1 = 50 - 1 = 49

P value (χ^2 49 > 84.410) = 0.00125

p = 0.0013

p < α ie 0.05

So, H0 is rejected

Hence we state that standard deviation is > 8 miles per hpur
