Triangle Review 2.0 (Math i need help please)

Answers

Answer:

A= 30

Step-by-step explanation:

This requires several steps.

First, you need to find the 2 other missing angles.

One can be found easily by substracting 130 from 180

so 180-130 = 50

The other angle is the same as 8x+4

Now set up your equation

180=3x-6 + 8x+4 +50

180 = 3x + 8x -6 + 4 +50

180+6-4-50 = 11x

132 = 11x

132/11 = x

12 = x

Now plug in 12 for x in your angle A

A=3x-6

A=3 * 12 - 6

A=36 - 6

A= 30

Answers

Answer:

its C

Step-by-step explanation:

The box plot which correctly displays the data set with the given values is A. The number line goes from 0 to 25. The whiskers range from 3 to 24, and the box ranges from 6 to 19. A line divides the box at 15.

What is Box Plot?

Box plot, which is also known as box and whisker plot, is a method of graphically representing the measures like minimum, maximum and the quartiles of the data set.

Here three box and whiskers plots are given.

We have to find the box plot where,

Maximum point = 24

Minimum point = 3

Median = 15

Upper quartile = 19

Lower quartile = 6

Here the range of the whiskers depicts the maximum and minimum point.

So, the whisker must range from 3 to 24.

The range of the box depicts the quartile range.

So box must range from 6 to 19.

A line will be dividing in between which depicts the median.

So the line must be at 15.

Hence the correct plot is the number line goes from 0 to 25. The whiskers range from 3 to 24, and the box ranges from 6 to 19. A line divides the box at 15.

A laundry basket contains 8 white t-shirts and 6 black t-shirts. What is the probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back?

Answers

Answer:

30/182 = 15/91.

Step-by-step explanation:

PROBABILITY: the likelihood of an event.

There are a total of 14 shirts in the basket.

Of the 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.

The probability of picking a black shirt is 6 in 14, or 6/14.

The probability of picking a white shirt is 8 in 14, or 8/14.

WITHOUT REPLACING: This means that you take one without putting it back. (There will be one less).

6/14 × 5/13 = 30/182.

30/182 = 15/91.

The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back is 15/ 91.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

There are a total 14 shirts in the basket.

Out of the total of 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.

The probability of picking a black shirt = 6/14.

The probability of picking a white shirt = 8/14.

The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back

= 6/14 × 5/13

= 30/182.

= 15/91.

S = 15.47 units

Step-by-step explanation:

First, convert the degree angle into radians:

68° × (π/180) = 1.19 rad = theta

The arc length S is given by

S = r × theta

= (13 units)(1.19 rad)

= 15.47 units

Answer:

15.43

Step-by-step explanation:

The formula = angle / 360 × circumference

= angle / 360 × pi diameter

= 68 / 360 × pi × 13 + 13

= 68 / 360 × pi × 26

= 17 / 19 × pi × 26

= 221 / 45 pi

Answer:

[tex]143.8\:\mathrm{ft^2}[/tex]

Step-by-step explanation:

The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:

Area of semi-circle (half the area of a circle): [tex]\frac{1}{2}\cdot 4.5^2\cdot \pi[/tex]

Area of trapezoid (average of bases multiplied by height): [tex]16\cdot 7[/tex]

Thus, the total area of the figure is:

[tex]\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}[/tex]

Measure of Arc JM = 160°

Step-by-step explanation:

We know that the sum of the measures of the angles within a circle all add up to 360°, so we can say:

(53) + (79) + (68) + (Arc JM) = 360

200 + Arc JM = 360

Arc JM = 360 - 200

Arc JM = 160

Hope this helps!

Answer:

mJM = 360 - (53 + 79 + 68)

mJM = 360 - 200

mJM = 160º

Follow the steps below:1. Read two integers from the user.2. Suppose one of the integers is 2311062158. The binary equivalent of this integer stored in a register will be 1000 1001 1100 0000 0000 0010 1000 1110. This data should be regarded as bit strings representing subsets of the set {1, 2, 32}. If the bit string has a 1 in position i, then element i is included in the subset. Therefore, the string: 1000 1001 1100 0000 0000 0010 1000 1110 corresponds to the set: {2, 3, 4, 8, 10, 23, 24, 25, 28, 32}.3. Print out members of the set from smaller to larger. You can do a loop from 1 to 32. Load a masking bit pattern that corresponded to the position number of the loop counter (0x00000001 for 1). Isolate the bit in the operand by using the AND operation. If the result of the AND is not 0 then the loop counter is in the set and should be displayed. Increment the counter and shift the masking bit pattern to the left.4. Read a number from the user. Determine if that element is a member of the given sets.5. Determine the union of two sets.6. Determine the intersection of two sets.7. Implement a loop back to the main function. See the prompts below: "Enter the first number:" "Enter the second number:" "Members of Set 1:" "Members of Set 2:" "Enter an element to find:" "It is a member/ not a member of set 1" "It is a member/ not a member of set 2" "Union of the sets:" "Intersection of the sets:" "Do you want to compute set functions again?"8.
