Answer:

Step-by-step explanation:

Expand the brackets = 2x + 6 - 3x - 4

The equation is now -1x + 6 - 4

Take 4 from 6 to get 2

The equation is now -1x + 2, which is equal to option C

Let there are x no of runners. ATQ,

$\dfrac{1}{8}x=\dfrac{1}{2}\\\\x=\dfrac{(1/2)}{(1/8)}\\\\x=16$

So, there are 16 runner that are needed for each relay race group.

Refer to the various selling prices of various homes in a community that follow the normal distribution with mu (population mean

blsea [12.9K]

Answer:

0.43715

Step-by-step explanation:

We solve using z score calculator

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = $276,000

σ is the population standard deviation = 32,000

For x = $276,000

z = 276,000 - 276,000/32000

z = 0

Probability value from Z-Table:

P(x = 276000) = 0.5

For x = $325,000

z = 325,000 - 276,000/32000

z = 1.53125

Probability value from Z-Table:

P(x = 325000) = 0.93715

The probability that the next house in the community will sell for between $276,000 and $325,000 is

P(x = 325000) - P(x = 276000)

= 0.93715 - 0.5

= 0.43715

Step-by-step explanation:

ABC is an isosceles triangle that has a 130° angle at vertex B

then

m∠A = (180 - 130)/2 = 50/2 = 25 = m∠C

then

m∠A = m∠C = 25°
