B - Side = 16 cm, side = 9 cm, side = 7 cm

C - Side = 17 cm, side = 12 cm, side = 7 cm

D - Side = 17 cm, side = 11 cm, side = 5 cm

Answers

Answer:

Step-by-step explanation: Three line segments can form a triangle, if the sum of any two lengths is greater than the third length. In A), 8 + 7 = 15 < 16. So, A cannot form a triangle.

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

find the diameter and of each circle. A) circumference = 118mm B) circumference = 1m

Answers

Okay so the formula for circumference is

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.

3. $595 refrigerator; 22% discount.

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:

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

find the time required for an investment of $3000 to grow to $8000 at an interest rate of 7.5% per year, compounded quarterly ( round the answer to two decimal places)​

A company makes 150 bags.
23 of the bags have buttons but no zips.
35 of the bags have zips but no buttons.
49 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?

Answers

Answer:

66/150

Step-by-step explanation:

So the question asks the probabilty for buttons.

so we see that 23 has buttons so we discard for now,

35 has no buttons but a zip so we acknowledge it

49 has no buttons and no zips so we keep it too.

now we do 35+49 which is 84.

since there is 150 bags and 84 of those bags dont have buttons, the rest must do.

150-84=66

so there are 66 bags with buttons so we put this in a fraction -> 66/150

Tangent (non necessary for the question persay):

since we cant simplify you keep it as 66/150. If you are doing this on mathswatch, then remeber if there is a question like this next and you can simplify, simplify.

for this question it is not necessary.

Mathswatch users only:

Also a trick for mathswatch if you get it wrong, go to task bar, search the task name (it will be below search/taskbar) then type number press enter and you have 2 more turns. You can repeat this how many times you need to.

The probability that the bag is selected at random have buttons is 11/25.

What is probability?

Probability is the chance of happning an event among all the events possible. It lies between 0 and 1. It is calculated by dividing number of items by total number of items.

How to calculate probability?

We have been given that company makes 150 bags out of which 23 of the bags have buttons but no zips and we have to calculate the probability that a bag chosen at random have buttons.

35 of the bags have zips but no buttons.49 of the bags have neither zips nor buttons.so we see that 23 has buttons so we discard for now, 35 has no buttons but a zip so we can say that it that 49 has no buttons and no zips so we keep it too.now we do 35+49 which is 84. Because there are  150 bags and 84 of those bags dont have buttons, the rest must do.

150-84=66, we got that there are 66 bags with buttons so we put this in a fraction= 66/150.

Probability=66/150

Hence the probability of getting a bag that has buttons is 66/150.

Answers

Answer:

79.5

Step-by-step explanation:

cos p = 73^2+35^2-75^2/2(73)(35)

cos p= 9229/5110

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

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.
