The null hypothesis should not be rejected. There is insufficient evidence that the true diameter differs from 0.5 inches.
We are given that,
n = 15
t-value = 1.66
Significance level;α = 0.05
So, DF = n - 1 = 15 - 1 = 14
In the attached one-sample t-table, we can see that the p-value of 0.06
corresponds to a t-value of 1.66 and a DF of 14
Due to the P-value of 0.06, it is greater than the significance level of 0.05. Based on the results, we are not rejecting the null hypothesis. There is insufficient evidence to conclude that the true diameter in active attachment is different from 0.5

Work out the total amount of money tom earned on monday
The money earned by Tom in accordance with his rate is $
In mathematics, comparing two related quantities stated in different units is known as a rate.
If the denominator of the ratio is stated as a single unit of one of these quantities and it is assumed that this number may be changed systematically, the numerator of the ratio expresses the comparable rate of change in the other (dependent) variable (i.e., is an independent variable).Speed, heart rate, and flux are a few examples of rates that are frequently expressed as "per unit of time." Electric field ratios, exchange rates, and literacy rates are a few instances of ratios with a non-time denominator (in volts per meter).The rate at which he earns is $15 per hour.
He earns over time at 1 1/3 times his wage
Overtime rate = 4 / 3 × 15 = $20
He worked for 11 hours.
Total money earned = 7 hours at rate $15 per hour and 4 hours at rate $20 per hour.
Money earned = 7 × 15 + 20 × 4 = $185
Hence the money earned at that rate is $185.

A) The end behavior of the polynomial graph is that;
as x → -∞, y → -∞, and as x → ∞, y → ∞
B) The given graph polynomial represents an even degree polynomial.
What is the End behavior of the graph?The end behavior of the graph of a polynomial function is the behavior of the graph of as approaches positive infinity or negative infinity.
Now, we see from the graph that as x approaches a larger value, y values are getting increasingly negative. This means that as x approaches negative infinity, the values of y approach negative infinity.
In a similar approach, we can see that as the values of x approach positive infinity, the values of y also approach positive infinity.
Thus, we can say that option D is correct.
B) Odd-degree polynomial functions, are those that have graphs that extend diagonally across the quadrants while even-degree polynomial functions are those that have graphs that open upwards or downwards.

the world record for most selfies taken simultaneously is 4296. this is 51 fewer than three times the world record for the most selfies taken by one person in one hour. what is the world record for the most selfies taken by one person in one hour?
The world record for most selfies taken by a person in one hour is calculated to be 1449.
The world record for the most selfies taken by one person in one hour can be determined by using an algebraic expression.
As 4296 is 51 fewer than three times the World record for the most selfies taken by one person in one hour, we can consider x to be the world record by which we get an algebraic expression as follows;
3x - 51 = 4296
Solving for x;
3x = 4296 + 51
3x = 4347
x = 4347 / 3
x = 1449
Therefore, 1449 is calculated to be the world record for most selfies by one person in one hour.

-27 = -w/5 solve for w and simplify as much as possible and put the anwser
Answer:
w = 135
Step-by-step explanation:
-27 = -w/5
multiply both sides by 5:
5(-27) = 5(-w/5)
-w = 135
divide both sides by -1:
-w/-1 = 135/-1
w = 135
The value of w is 135 in the equation -27 = -w/5 .
We are provided with the equation mentioned below:
-27 = -w/5
As per the question we have to simplify and solve this above mentioned equation. To simplify this provided equation we will follow the steps mentioned below:
-27 = -w/5 equation 1
On multiplying both the sides of equation 1 with 5, we will get
(-27) × 5 = (-w/5) × 5
- 135 = -w equation 2
On multiplying both the sides of equation 2 with -ve sign, we will get
w = 135

His lifetime earnings when he retires at the age of 68 is $2,817,385.1728.
The total number of years Demarcus will work is 68 - 24 = 44 years.
Now, there are about 52.1429 weeks per year; therefore, the number of weeks in 44 years will be:
44 years × 52.1429 weeks/year = 2294.2876 weeks
We are also told that Demarcus gets paid once every two weeks; this means the number of payments made in 44 years will be:
2294.2876 / 2 = 1147.1438 payments
Since each payment is worth $2,456.00, the total amount earned from 1147.146 payments will be:
1147.146 payments × 2456 per payment = $2,817,385.1728
Hence, Demarcus' lifetime earnings if he retires at the age of 68 will be $2,817,385.1728.
