What is the expected value of the spinner shown?

What is the multiplicative rate of change of the exponential function represented in the table? 1.5 2.25 3.0 4.5

Sati [7]

Use the geometric sequence formula to solve for rate:
an=a1r^(n-1)

6.75=4.5r^(2-1)
6.75=4.5r
6.75/4.5=r
r= 1.5
and if you want to make sure just multiply each number by 1.5 and see if it gets you the next number
4.5 4.5×1.5=6.75 (holds true)
6.75 6.75×1.5=10.125 (holds true)
10.125 10.125×1.5=15.1875 (holds true)
15.1875

1.5 is the multiplicatice rate hope that helps :)

ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°, what is the value of m?

Digiron [165]

Answer:

The correct answer is option B. 17

Step-by-step explanation:

It is given that, ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°

To find the value of m

From the figure we can see that, triangle WYZ is an isosceles triangle.

ZW = ZY

Then <YXZ = <WXZ = 90°

It is given ∠YXZ = (6m – 12)°

(6m – 12)° = 90°

6m = 90 + 12 = 102

m = 102/6 = 17

Therefore the value of m = 17

The correct answer is option B. 17

Tia Veronica Pam and Lily are sisters. Tia is eight years old and she’s two years older than Pam. Pam is five years younger than

Nastasia [14]

Answer:

Pam (6 years), Tia(8 years), Veronica(11 years) , Lily (15 years)

Step-by-step explanation:

Age of Tia = 8 years

______________________________________________

Given Tia is 2 years older than Pam

mathematically

age of Pam + 2 years = age of Tia

age of Pam + 2 years = 8 years

age of Pam = 8 years- 2 years = 6 years

______________________________________________

Given Pam is five years younger than Veronica

we can infer that age of veronica is age of Pam + 5 more years

mathematically

age of Pam + 5 years = age of Veronica

6 years + 5 years = age of Veronica

age of Veronica = 11 years

______________________________________________

Given Veronica is four years younger than Lily

we can infer that age of Veronica is (age of Lily - 4 years)

mathematically

age of Veronica = age of lily - 4 years

11 years = age of lily - 4 years

age of lily = 11 years + 4 years = 15 years

age of lily = 15 years

______________________________________________

Arranging the list from youngest to oldest we have

age of Pam = 6 years

Age of Tia = 8 years

age of Veronica = 11 years

age of lily = 15 years

Arranging sisters in order of youngest to oldest

Pam, Tia, Veronica , Lily
