Answer:

a4 = 128

a5 = -512

Step-by-step explanation:

a1= -2

q= (-1)^(n+1) × 4

a4 = a1q³ = (-2) (-4)³ = -2 × -64 = +128

a5 = a1q⁴ = (-2) (-4)⁴ = -2 × 256 = -512

Answer:

15 is a composite number. 15 = 1 x 15 or 3 x 5. Factors of 15: 1, 3, 5, 15. Prime factorization: 15 = 3 x 5

Step-by-step explanation:

Answer:

15= 3 x 5

Step-by-step explanation:

                            15

                        /      /

                      5   x    3

3 and 5 both multiply together to make 15

Observing the given matrix we can say that:

1) The value is 4.

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.

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:

5

Step-by-step explanation:

There are 4 equal sides on a square so 20/4 which is 5.

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

Answer:

14

Step-by-step explanation:

Divide

84 ÷ 3

= 28

28 ÷ 2

= 14

Therefore, there has to be 14.

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

Answer:

32

Step-by-step explanation:

work backwards, 19-11=8 then x 4 makes 32.

Answer:

32

Step-by-step explanation:

Let the number be 'x'

[tex]\dfrac{x}{4}+11=19[/tex]

Subtract 11 from both sides

[tex]\dfrac{x}{4}=19 - 11\\\\\dfrac{x}{4}=8\\[/tex]

Multiply both sides by 4

x = 8*4

x = 32

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

                         I hope this helps, have a nice day! :D

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;

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

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

Answer:

75 000 000

Step-by-step explanation:

7 500 000 times 10 = 75 000 000

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°

The length of the wire AC is 61 meters.

Pythagoras theorem is used to show the relationship between the sides of a right angled triangle.

We can find the length of wire AC using Pythagoras theorem:

AC² = 60² + (66 - 55)²

AC² = 60² + 11²

AC² = 3721

AC = 61 meter

The length of the wire AC is 61 meters.

Answer:

Step-by-step explanation:

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.

I'm kinda bad at explaining things in words, so sorry if this makes no sense, but I hope this helps!
