Answer:

A - 84°

Step-by-step explanation:

The measure of an arc is equal to the measure of the central angle that intersects it.

The central angle of this circle measures 84° and it intercepts arc AB, meaning arc AB measures 84°

skad [1K]

Answer:

Y = 12

Step-by-step explanation:

x + 1/3y = 4

Multiply both sides of the equation by 3.

3 ⋅ 1 3 ⋅ y = 3 ⋅ 4

Simplify both sides of the equation:

1. Simplify both sides of the equation.

2. Multiply 3 by 4

How to simplify:

Cancel the common factor of 3

Rewrite the expression.

Multiply by 1

y = 3 ⋅ 4

Multiply 3 by 4

What is the circumference of a circle with a diameter 9cm

xz_007 [3.2K]

The circumference follows the formula
C= 2 (pi)R
R is the radius which is half the diameter when we put this into the equation we get
C = 2 (pi)(4.5)
C=28.274334

Doing research for insurance rates, it is found that those aged 30 to 49 drive an average of 38.7 miles per day with a standard

Alja [10]

Answer: 0.4302

Step-by-step explanation:

Given : Mean : $\mu=\text{38.7 miles }$

Standard deviation : $\sigma=\text{6.7 miles }$

Sample size : $n=60$

Also, these distances are normally distributed.

Then , the formula to calculate the z-score is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x=32.5

$\\\\ z=\dfrac{32.5-38.7}{6.7}=-0.925373134\approx-0.93$

For x=40.5

$\\\\ z=\dfrac{40.5-38.7}{6.7}=0.268656\approx0.27$

The p-value = $P(-0.93$

$=P(0.27)-P(-0.93)=0.6064198- 0.1761855=0.4302343\approx0.4302$

Hence, the required probability :-0.4302

Hazel is putting together charm bracelets. For each bracelet she uses

Reika [66]

Answer:

37/96

Explanation:

Hazel uses 1yd for 60 charms, so for 5/8yd she would use 5/8×60=37.5.

Because she can’t use a fraction of a charm, she would use 37 charms which is 37/96 of the charms she has.
