What is x when 44x=78

Answers

X= 1.77
Hope this helps :)

Answer:

≈ 1.77

Step-by-step explanation:

So we are looking for x in 44(x) = 78.

All we have to do is isolate the variable, get x by itself.

Divide 44 by both sides :

[tex]\frac{44x}{44} = \frac{78}{44}[/tex]

[tex]x = 1.772727272723[/tex]

Which can be rounded to 1.77

Name Each of the vertices on the quadrilateral

Answers

The names of the vertices (or corners) are the letters next to them. However you may need to write the plot points, so you would look at the left side or the    y axis and count where the dot is as a number. Lets say its D. D is 4 on the y axis. Then you would go straight down to find the x axis. It is right over three. than you would write it with the x axis ALWAYS first. So D is (3,4).

In horse racing, a trifecta is a type of bet. To win a trifecta bet, you need to specify the horses that finish in the top three spots in the exact order in which they finish. If eight horses enter the race, how many different ways can they finish in the top three spots

Answers

Answer: 336 different ways

Step-by-step explanation:

Ok, we have a total of 8 horses, and we have 3 places.

First, second, third.

The total number of combinations will be equal to the product of the number of possible options that we have in each place.

For the first place, we could have any of the 8 horses, so there are 8 possible options.

For the second place, we will have 7 horses (because one is already in the first place) then here we have 7 options.

For the third place, we will have 6 horses (because one is in the first place and another is in second place) then here we have 6 options.

The total number of different ways in which the horses can finish is:

C = 8*7*6 = 336 different ways

Mr. Kershner is a school nurse. He uses, on average, 24 self-adhesive bandages during each spring month: March, April, and May. He also knows that in June there are several field days and he will need 4 times the number of bandages for that month.

If the bandages cost 3 cents each, what is his total cost for March through June?

Answers

If the bandages cost 3 cents each,  Mr. Kershner's total cost for bandages from March through June is $5.04.

What is an arithmetic operation?

Arithmetic operations is a branch of mathematics, that involves the study of numbers, the operation of numbers that are useful in all the other branches of mathematics. It basically comprises operations such as Addition, Subtraction, Multiplication, and Division.

The number of bandages used by Mr. Kershner in March, April, and May is 24 bandages each month, for a total of 24 x 3 = 72 bandages for those three months.

In June, he will need four times as many bandages as in the other months, for a total of 4 x 24 = 96 bandages.

The total number of bandages used from March through June is 72 + 96 = 168 bandages.

The cost of each bandage is 3 cents, so the total cost for 168 bandages is 168 x 3 = 504 cents, or $5.04.

Therefore, Mr. Kershner's total cost for bandages from March through June is $5.04.

Find the values of x and y.

Answers

Answer:

x = 67

y = 169

Step-by-step explanation:

We know that (x-1) + 52 + (y-7) = 180 because they're all on the same straight line. We also know that x-1 = 66, because they are alternate interior angles.

Solve for x:

x-1 = 66

x = 67

Now solve for y:

(67-1) + 52 + (y-7) = 180

y = 169

Answers

Answer:

It's 99%

Step-by-step explanation:

It just is.

A confidence interval for the true mean for all WHS seniors is 512.00 ± 47.8." The confidence level for this interval is 99%. The correct option is D.

What is the percentage?

The percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole. When expressing a sum as a percentage, 100 equal components are regarded to make up the whole.

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Divide the amount by the total value to get the percentage, then multiply the resulting number by 100.

Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

Therefore, the correct option is D, 99%.

Of people who died in the United States in recent years, 86% were white, 12% were black, and 2% were Asian. (This ignores a small number of deaths among other races.) Diabetes caused 2.8% of deaths among whites, 4.4% among blacks, and 3.5% among Asians. The probability that a randomly chosen death is a white person who died of diabetes is about:____

Answers

Answer:

The probability that a randomly chosen death is a white person who died of diabetes is of 0.0241 = 2.41%.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: The person is white

Event B: Died of diabeters.

Of people who died in the United States in recent years, 86% were white

This means that [tex]P(A) = 0.86[/tex]

Diabetes caused 2.8% of deaths among whites

This means that [tex]P(B|A) = 0.028[/tex]

The probability that a randomly chosen death is a white person who died of diabetes is about:

This is [tex]P(A \cap B)[/tex]. So

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

[tex]P(A \cap B) = P(B|A)*P(A) = 0.028*0.86 = 0.0241[/tex]

The probability that a randomly chosen death is a white person who died of diabetes is of 0.0241 = 2.41%.

A triangle has sides with lengths of 7 yards, 8 yards, and 9 yards. Is it a
right triangle?

Answers

Answer:

No, it is not a right triangle.

Step-by-step explanation:

A right triangle will follow the Pythagorean Theorem: a² + b² = c²

c is the hypotenuse, or the longest side. In this case, it is 9.

That means a and b are 7 and 8.

Now let's plug in the values to see if they simplify correctly.

(7)² + (8)² = (9)²

Simplify the exponents.

49 + 64 = 81

Add the left side.

113 = 81

The above expression is not true; therefore, this triangle is not a right triangle.
