Answer:

Side AC is common to both triangles.

The two triangles are thus congruent by SAS (side and angle are given, second side is shared).

The angle opposed to AC for the top triangle (ie B) is congruent to the angle opposed to AC for the bottom triangle (ACD), QED.

Answer:

5√8, √170, 5/8, 0.62

Step-by-step explanation:

5√8 = 14.1

√170 = 13.03

5/8 = 0.625

0.62 = 0.62

Answer:

5sqrt(8), sqrt(170), 5/8, 0.62

Step-by-step explanation:

Solve any equations and put them in decimal form to make it easier to list them from biggest to smallest.

Ex: sqrt(170) = 13.04

5sqrt(8) = 14.14

5/8 = .625

14. The supervisors of a rural county are interested in the proportion of property owners who
support the construction of a new high school for the area. Rather than contact all 7,000 of
the owners, the supervisors decide to take a random sample of 300.
(a) During each interview, the supervisor's representative asks, “Do you support the building
of a new high school for the area?” For this sample, 58% of the respondents said yes. If
the representative took a second random sample of 300 property owners, would this
second sample proportion of those who support building a new high school be exactly the
same as that found in the first sample?
(b) If the representative has increased the sample size to 600 owners, what effect would this
have on the estimated proportion of owners who would support building the high school?

Step-by-step explanation:

these are all isoceles triangles (2 sides are equal). that also means that the 2 angles at the end of the equal sides are equal.

so, the angle at F and H are both 65°.

the angle at J = 2×65 = 130°.

the angle at G = 2×(180 - 65 - 65) = 2×50 = 100°.

remember, the sum of all angles in a triangle is always 180°.

so many ways now to get y.

let's use the triangle GH and crossing point of diagonals (there is a right angle).

y = 180 - G/2 - 90 = 180 - 50 - 90 = 40°

Aliza plays basketball every Tuesday and
Thursday. She practices piano every other
day. If June started on a Monday, and if
Aliza played piano that day, on how many
days did she both play basketball and practice piano in June (which has 30 days)?
A. 2 days
B. 4 days
C. 5 days
D. 7 days

Answers

Answer:

4 days

Step-by-step explanation:

June starts on Monday

for 30days we have 4 weeks starting from Monday to Sunday and extra 2 days which are Monday and Tuesday

so we have 5 mondays and tuesdays

4 wed, thu, fri, sat, sun

Aliza played piano on june1 monday

So aliza played basketball on 5 tues + 4 thurs = 9 days

for calculating both basketball and paino

piano day should be on tuesday or thursday

from the below picture u can see pink dots are piano days

and yellow circles are both piano and basketball days

so on alternate weeks they are coinciding

so there are 4 days

Answer:

y = - [tex]\frac{4}{3}[/tex] x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line

m = [tex]\frac{-2-2}{3-0}[/tex] = [tex]\frac{-4}{3}[/tex] = - [tex]\frac{4}{3}[/tex]

The line crosses the y- axis at (0, 2 ) ⇒ c = 2

y = - [tex]\frac{4}{3}[/tex] x + 2 ← equation of line

1: Angles 2 & 6 + angles 3 & 7

     - Angles that are on the inside of the parallel lines and on opposite sides of the transversal  

2: Angle 1

     - Angles in the same position but the other line

3: Alternate exterior angles

     - Angles that are on the outside of the parallel lines and opposite sides of the transversal

4: Same side interior angles

     - They are on the same side of the transversal and inside the parallel lines

5: Angle 2

     - It is supplementary and on the inside of the parallel lines

6: Angle 4

     - It is supplementary and on the outside of the parallel lines

7: 146°

     - They are corresponding angles, so they are the same measurement  

8: 128°

     - They are supplementary angles, so 180 - 52 = 128

For 9 & 10:

     - They are supplementary, so adding them together will result in 180 degrees

     - (8x + 63) + (5x) = 180 -> 8x + 5x + 63 = 180 -> 13x = 117 -> x = 9

     - Now we will plug it in to find the individual measurements:

9: 135°

     - 8x + 63 -> 8(9) + 63 -> 72 + 63 = 135

10: 45°

     - 5x -> 5 (9) = 45

Observing the given matrix we can say that:

2) The value is 2.

So analyzing the different paths that can connect city 1 to city 3: The value is 4. It represents the number of one-stop routes between City 1 and City 3 that pass through City 2.

For the second statement we will have the value is 2. It is the number of direct routes from  City 2 to City 5.

The angles in a quadrilateral ABCD are A(3x+10), B(3x+4), C(x+50) and D(5x+8). Find the angles of the quadrilateral ABCD

please answer it fast..thank u

Answers

Answer:

A  8º

B  76º

C  74º

D  128º

Step-by-step explanation:

The sum of the angles is 360

(3x + 10) + (3x + 4) + (x + 50) + (5x + 8) = 360

Combine like terms

12x + 72 = 360

Subtract 72 from both sides

12x = 288

Divide both sides by 12

x = 24

--------------

A (3x+10) = 3*24 + 10 = 82

B (3x+4) = 3*24 + 4 = 76

C (x+50) =  24 + 50 = 74

D (5x+8) = 5*24 + 8 = 128

Need to know the slope and the y intercept

Answers

Answer: Slope (M) = 7.5

Y-intercept (B) = 0

Step-by-step explanation:

For the slope, the first step is to find your "pretty points" (spots on the slope that hit the corner perfectly, like (0, 0) or (2, 15).

Now, make a triangle with the two points. Count the amount of squares on both. This will give you 3 and 4, but when taking the units into consideration, 15 and 2. The last step is to divide 15 and 2 which gives you 7.5. I would recommend writing both 15/2 and 7.5 but it's up to you.

The Y-intercept is just the spot where the Y is 0, or where the line touches the Y-axis. This is at the origin, where both X and Y are 0, so your Y-intercept is 0.

Why or why​ not?Is the distribution a standard normal​ distribution? Why or why​ not? Choose the correct answer.

Answers

The distribution is not a standard normal distribution.

We know that the variable (X) usually obeys and follows a standard normal distribution provided that the summation of (X) is zero and the variance of the random variable V(X) = 1.

Mathematically:

E(X) = 0 and V(X) = 1

Given that;

the mean which follows a normal distribution (X) = 4.5338 g, and the standard deviation SD(X) = 0.1039 g

As such, the distribution is not a standard normal distribution.

Therefore, we can conclude that the distribution is not a standard normal distribution.
