A Walton College of Business graduate, wants to start a hot dog stand on Dickson Street. He needs to raise $15,000 for start-up
Artist 52 [7]

Answer:

Yes, he is meeting his original goal to be successful.

The critical value is 1.833

Step-by-step explanation:

H0: mu = 300

Ha: mu > 300

The test is a one-tailed test because the alternate hypothesis is expressed using greater than.

Test statistic (t) = (sample mean - population mean) ÷ (sample sd/√n)

sample mean = 335

population mean = 300

sample sd = 50

n = 2×5 = 10

t = (335 - 300) ÷ (50/√10) = 35 ÷ 15.81 = 2.21

Degree of freedom = n-1 = 10-1 = 9

Significance level = 5%

Critical value corresponding to 9 degrees of freedom and 5% significance level is 1.833.

Conclusion:

Reject the null hypothesis because the test statistic 2.21 is greater than the critical value 1.833.

His original goal to be successful is contained in the alternate hypothesis, therefore, he is meeting it.

2 to the Third power -(30÷5) +9
OLga [1]

Answer:

11

Step-by-step explanation:

2^3-(30/5)+9

First, you divide 30/5 because it is in parentheses and we are following this rule for order of operations:

P- parentheses

E- exponents

M- multiplication

D- division

A- addition

S- subtraction

so 30/5 = 6 and plugged in is:

2^3-(6)+9

Next, we do exponents:

2^3 = 2x2x2 = 8

plugged back in:

8-(6)+9

Now, we do the math from left to right so:

8-6=2

2+9=11

11 is your answer

The circumference of one coin is 8.03cm. The circumference of another coin is 0.33cm smaller. A.) what is the first step to find
Burka [1]

Answer:

Diameter of the smaller coin = 2.46 cm

Step-by-step explanation:

Circumference of a coin = 2πr

Circumference of coin A = 8.03 cm

Circumference of coin B = 8.03 cm - 0.33 cm

A.) what is the first step to find the diameter of the smaller coin?

Find the circumference of coin B

Circumference of coin B = 8.03 cm - 0.33 cm

= 7.7 cm

B.) Find the diameter of the smaller coin.

Circumference of a coin = 2πr

7.7 = 2 × 3.14 * r

7.7 = 6.28r

r = 7.7 / 6.28

r = 1.23 cm

Diameter = 2r

= 2 * 1.23 cm

= 2.46 cm

Diameter of the smaller coin = 2.46 cm
