Kane is preparing for a marathon and initially runs 3 miles each training session, planning to extend his distance by a quarter mile each week. Denote w as the number of weeks; construct an expression that reflects the distance Kane covers during a training session after w weeks. The solution is given by: (11 + w) / 4. Explanation: He starts with 3 miles per session and adds 1/4 mile weekly. Thus, after w weeks, the distance becomes: = 3 + (w - 1) × 1/4 = 3 + (w/4 - 1/4) = (12 + w - 1) / 4 = (11 + w) / 4.

You have a fishing line spool with an end that has an area of 20.0 cm2. How much fishing line do you need to wind around the spo
PIT_PIT [12445]

Solution Procedure

Considering the spool as a cylindrical shape, and calculating the circumference based on the area cited, we establish the connection between circumference and area as follows:

... C = 2√(πA)

To find ten times this circumference, we calculate:

... 10C = 20√(π·20 cm²) = 40√(5π) cm ≈ 159 cm

Derivation of Formulas

The standard formulas for circumference and area are:

... C = 2πr

... A = πr²

Multiplying the area formula by π and extracting the square root yields:

... πA = (πr)²

... √(πA) = πr

Doubling this value results in the circumference formula:

... C = 2√(πA) = 2πr

tester [12383]

Response:

Step-by-step breakdown:

For the null hypothesis,

H0: p = 88

For the alternative hypothesis,

Ha: p < 88

In terms of population proportion, where the probability of success is p = 0.88

q represents the probability of failure = 1 - p

q = 1 - 0.88 = 0.12

Considering the sample,

Sample proportion, P = x/n

Where

x = number of successes = 21

n = total samples = 32

P = 21/32 = 0.66

Next, we determine the test statistic, which represents the z-score

z = (P - p)/√pq/n

z = (0.66 - 0.88)/√(0.88 × 0.12)/32 = - 3.83

The relevant p-value corresponds by referencing the normal distribution table for the area falling beneath the z-score. As a result,

P value = 0.00006
