Find The Missing Angle...

Answers

Answer 1

Answer:

15 degrees

Step-by-step explanation:

Because you add 115 and 50 to get 165. And we know that a triangles angles when added up will equal 180. So you subtract 180 and 165 to get 15 degrees, your missing angle!

Step-by-step explanation:

First, add the marbles together.

3 + 4 + 6 + 2 = 15

Then, put the 6 in the numerator.

6/15

Next, multiply by 2 to make the denominator 30.

12/30

Kay should expect 12 out of her 30 marbles to be green

Answers

Answer:

=z ^(-11) + ^(-15)

= z ^ -26

Answer:

z^-11 times z^-15 = z^-26

Step-by-step explanation:

According to exponential properties, multiplying two numbers that have exponents with the same bases should be added.

Negative exponents mean to go from a^-x to 1/a^x.

Using these properties, we evaluate the expression.

Both terms have the same base, z, so we can go ahead and add the exponents.

-11 + -15 = -26

z^-11 * z^-15 = z^-26

Because the instructions specifically say to leave it in z^n form, our answer is z^-26.

Solve w = x + for y.

Reply really fast and give like the work for it too please

Answers

Answer:

see below

Step-by-step explanation:

w = x+y/z

Subtract x from each side

w-x = x+y/z -x

w-x = y/z

Multiply each side by z

(w-x) *z = y/z*z

(w-x) *z = y

You can distribute the z if desired

wz -xz = y

Answer:

y = z(w - x)

Step-by-step explanation:

w = x + y/z

Subtract x from both sides

w - x = y/z

Multiply both sides by z

z(w - x) = y

Flip

y = z(w - x)

The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1800 hours and a standard deviation of 25 hours. Using the empirical rule, what percentage of light bulbs last between 1725 hours and 1875 hours?

Answers

Answer:

99.7%

Step-by-step explanation:

The empirical rule formula states that:

68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ

Step 1

We have to find the number of standard deviations from the mean

μ = Mean = 1800 hours

σ = Standard deviation = 25 hours

For 1725 hours

μ - xσ =

1800 - 25x = 1725

25x = 1800 - 1725

25x = 75

x = 75/25

x = 3

For 1875 hours

1800 + 25x = 1875

25x = 1875 - 180

25x = 75

x = 75/25

x = 3

Step 2

From the above calculation, the bum of standard deviations from the mean is 3

Hence, the percentage of light bulbs last between 1725 hours and 1875 hours is 99.7%

Terry rents a kayak while he is on vacation. He is required to pay a deposit of $95 plus an additional $11.50 per day. Terry only has $150 to spend on kayaking. Write and solve an inequality you can use to determine the maximum number of days Terry can afford to rent a kayak.

Answers

Answer:

A maximum of 4 days

Step-by-step explanation:

Inequality: 95 + 11.50x ≤ 150

Okay so the 95 is his fee. Then for everyday, it's 11.50 and we don't know how many days yet, so 11.50x. The 95 dollars and the 11.50x has to equal to or less than 150 since that is how much he has to spend on vaca.

95 + 11.50x ≤ 150

-95                   -95

11.50x ≤  55

/11.50       /11.50

X=4.78260869565

You would round down since he has a budget.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Quadrilateral RUST has a vertex at R (1,5)

We have to find the coordinates of R after the translation (x,y) of (x+ 1, y - 2)

(1, 5)-->(1+1, 5-2)

Coordinates after translation are (2, 3)

Now by a dilation by a scale factor of 3, centered at the origin

so R'(6, 9)

Do you think two students who made no computation errors would get different values for this numerical expression> explain (4x35)+(36x8

Answers

Answer:

Yes, they would get different values

Step-by-step explanation:

Given

[tex](4 * 35) + (36 * 8)[/tex]

Required

Would there be different value for the expression?

From the question, we understand that both students made no computational errors. This doesn't mean that the students cannot make other errors.

For instance, the expression can be solved (wrongly) in the following ways;

[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 140 + 36 * 8 \to 176 * 8 = 1408[/tex]

[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 4 * 71 * 8 \to = 2272[/tex]

While the correct solution is:

[tex](4 * 35) + (36 * 8) \to 140 + 288 =428[/tex]

Hence, it is possible for two students to get different values

What is data representation?

Data Representation: A method for analyzing numerical data is data representation. Data representation is used to create a diagram that shows the connections between facts, ideas, information, and concepts. It is a fundamental learning technique that is clear-cut and uncomplicated. The data type in a particular domain is always what determines it. There are many various styles and sizes of graphical representations.

According to the given data:

A building has 3 elevators.

The following set of random numbers represents 20 stimulations of the elevators, with 0, 1 representing the broken elevator and 2,3,4,5,6,7,8and 9 representing a working elevator.

Stimulation data:

931 188 763 841 559 144 652 277 653 673 404 396 011 843 599 797 414 761 273 844

Now, as we observe from the given data, the stimulation in which all three elevators are working are-

763,559,652,277,653,673,396,843,599,797,273,844a total of 12 stimulations.

Thus, the total stimulations in which all three elevators are working is 12
