Answer:

10 degrees

Step-by-step explanation:

The answer is 10 degrees because the angle is complementary which means its going to be 90 degrees so all you have to do to find the answer is add 50+30 and boom 10 degrees

<h3>Answer:   80</h3>

====================================================

Explanation:

There are probably many approaches here, but one way to do this is to extend segment DO to form a line. Check out the diagram below. This line is in red.

The goal is to have this line extend to intersect with line AB. Let's call this intersection point E.

In that diagram, I've marked the variable y as angle EOB. Notice that angles BEO and CDO are congruent alternate interior angles (since lines AB and CD are parallel). So that's where that extra 30 degree angle comes from.

Focus on triangle EOB. The three angles of any triangle always add to 180

E+O+B = 180

30+y+50 = 180

y+80 = 180

y = 180-80

y = 100

The last step is to solve the equation below for x

x+y = 180

x+100 = 180

x = 180-100

x = 80

This works because angles x and y are supplementary. They form a straight angle.

An entrepreneur faces many bureaucratic and legal hurdles when starting a new business. The World Bank collects information abou
slamgirl [31]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data :

Rearranged data:

5, 5, 5, 5, 6, 7, 7, 7, 8, 12, 12, 13, 13, 15, 18, 18, 27, 28, 36, 48, 52, 60, 66, 94

Start time for Suriname = 694

Mean = ΣX / n

Mean = (567 + 694) / (24 + 1) = 1261 / 25 = 50.44

B.) median start Time for initial 24 values

0.5(n+1)th term

0.5(25) = 12.5th term

(13 + 13) / 2 = 13

C.) preferred measure of center for the distribution will be the median as it shapes well in the middle of the distribution. The mean is overestimated

d) Compute the quartiles (Q1, Q2, Q3), and find the IQR for these data. Are there outliers in the time to start a business data set? If so, identify and name any outliers.

Using calculator :

Lower quartile Q1 --> 7

Median Q2 --> 13

Upper quartile Q3 --> 42

IQR = (Q3 - Q1) = 42 - 7 = 35

OUTLIER:

Lower bound : Q1 - 1.5(IQR) ; 7 - 1.5(35) = - 45.5

Upper bound : Q3 + 1.5(IQR) = 42 + 1.5(35) = 94.5

Outlier : values below - 45.5 and above 94.5

Hence, Surimanes start time is the only Outlier.

e)

Standard deviation for 24 countries :

Standard deviation = sqrt[Σ(X - mean)^2 / (N - 1)]

Usibg calculator :

Standard deviation for the 24 countries is 23.83

f)

Slope is –2 &amp; (5, 3) is on the line.<br> Y-Intercept:<br> Equation of the line (no spaces):
insens350 [35]

Answer:

y-int: (0, 13)

Equation: y = -2x + 13

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

<em>m</em> = slope

<em>b</em> = y-intercept

Step 1: Define variables

<em>m</em> = -2

Random point (5, 3)

Step 2: Plug in known variables

y = -2x + b

Step 3: Find y-intercept <em>b</em>

3 = -2(5) + b

3 = -10 + b

b = 13

Step 4: Rewrite equation

y = -2x + 13

Leah's family traveled 5/7 of the distance to her grandmother’s house on Saturday. They traveled 1/2 of the remaining distance o
Readme [11.4K]

Answer:

1/7

Step-by-step explanation:

They traveled 5/7 of the distance on Saturday.

That left 2/7 of the distance as the remaining distance.

They traveled half of 2/7 of the distance on Sunday.

1/2 of 2/7 = 1/2 × 2/7 = 2/14 = 1/7

Answer: 1/7

Which of the following statements about trapezoids is true? 
maw [93]

    D one pair of opposite sides is parallel is the answer because trapezoids are another pair angled towards each and if  you follow long enough they will intersect. A couldn't be true because if ALL the angles are corresponding angles you would need two pairs of parallel lines. B isn't correct because the sides would need to be parallel for that too. C well you've already proved they don't have two pairs of parallel lines.

Hope this helps :)
