In ΔPQR, p = 75 inches, q = 73 inches and r=35 inches. Find the measure of ∠P to the nearest 10th of a degree.
Answers
Answer:
79.5
Step-by-step explanation:
a^2 =b^2+ c^2-2bc cos A
cos p = 73^2+35^2-75^2/2(73)(35)
cos p= 9229/5110
cosp=79.5
The measure of ∠P to the nearest 10th of a degree is 79.5
What is a cosine law?Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.
u² = s² + t² - 2(s)(t)·cos U
We are given that In ΔPQR, p = 75 inches, q = 73 inches and r=35 inches.
u² = s² + t² - 2(s)(t)·cos U
Now substituting;;
cos p = 73²+35²-75² /2(73)(35)
cos p= 9229/5110
cosp=79.5
The measure of ∠P is 79.5

3. $595 refrigerator; 22% discount.
Show the work
Answers
Answer:
Discount: $130.90
Total cost after discount: $464.10
Step-by-step explanation:
Since I don't know what the actual question is, I will solve for the discount:
595 × 22%
Convert percentage into decimal
595 × 0.22
130.9
Discount is 130.9
Now I'll solve for how much that will take off from the original price:
595 - 130.9

3 pound of apples for $4.59.
Answers
Answer:
each apple would be $1.53
Answer:
$1.53 per pound of apple
Step-by-step explanation:
I'm assuming the question is what is the cost of 1 pound
Set up a equation:
3pounds/$4.59 = 1pound/x
Variable x = cost for one pound
3/4.59 = 1/x
Cross mulitply
3 × x = 4.59 × 1
3x = 4.59
Divide both sides by 3
3x ÷ 3 = 4.59 ÷ 3
x = 1.53

Answers
C=(pi)(D)
or
C=(pi)(2)(r)
But since they gave us the diameter we are gonna have to use the first formula.
Now I don’t know if they want u to use 3.14 for pi or the actual number, so i’m gonna assume we are using the actual formula.
So the formula to be able to find the diameter of circle A is going to be:
118/pi.
So put that into your calculator and you get 37.5605mm or 37.56mm.
It depends on what place your instructor wants you to round to.
The formula for circle B is going to be:
1/pi.
So let us put that into our calculator and you get 0.318309mm etc. Or just 0.3183.
I believe that I am correct but if i’m not please correct me.

The time spent watching a movie. Discrete or Continuous?
Answers
Answer:
The durations of movies in minutes can only take on integer values from 0 to 60. Therefore, it is a discrete data.
The time spent watching a movie is an example of Continuous function.
What is the difference between Discrete and Continuous?We gather information to look for connections, patterns, and other ideas. For instance, if you keep track of how many push-ups you perform every day for a month, your overarching objective is to assess your development and rate of advancement. For example heart beat rate, signal, etc.
Numerical information that is continuously referred to the undefined variety of measurements that might be taken across two realistic sites. For example - time, wind, temperature, pressure, etc.
Despite the fact that these numbers are often gathered via accurate measurements, they are also not necessarily neat and orderly as those in categorical data.
The time spent watching a movie is an example of Continuous function.

An engineer designs an improved light bulb. The previous design had an average lifetime of 1200 hours. The mean lifetime of a random sample of 2000 new bulbs is found to have a mean lifetime of 1201 hours. Although the difference from the old mean lifetime of 1200 hours is quite small, the P-value is 0.03 and the effect is statistically significant at the 0.05 level. If, in fact, there is no difference between the mean lifetimes of the new and old designs, the researcher has:________
a. committed a type 1 error
b. committed a type 2 error
c. a probability of being correct, which is equal to the P-value
d. a probability of being correct, which is equal to 1-(P-value)
Answers
Answer:
a. committed a type 1 error
Step-by-step explanation:
The correct option is - a. committed a type 1 error
Reason -
Type 1 error occurs when a true null Hypothesis is rejected
Type 2 error occurs when a false null Hypothesis is accepted
Now,
Let us state that,
The null hypothesis and alternate hypothesis is
H0 : There is no difference between the mean lifetimes of the new and old designs
H1 : There is a difference between the mean lifetimes of the new and old designs
Now,
As there is no difference between the mean lifetimes of the new and old designs.
⇒ The null hypothesis is true.
But p value suggests that null hypothesis should be rejected
∴
We have committed a Type 1 error that is rejecting a true null hypothesis.
So,
The correct option is - a. committed a type 1 error
