The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20

.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser. The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements.
0.40 x + 20 less-than 200

Which best describes the number of bars the band can order?
They can order from 0 to 449 bars, but no more.
They can order from 0 to 450 bars, but no more.
Their order must contain 451 bars or more.
Their order must contain 452 bars or more.

Step-by-step explanation:

just think it through :

0.4x + 20 < 200

0.4x < 180

x < 180/0.4 = 450

so, x < 450

they must order less than 450 bars.

therefore, the first answer option is correct :

they can order from 0 to 449 bars, but no more.

Evaluate the expression below using the properties of operations. Show your steps.−36 ÷ 14 ⋅ (−18) ⋅ (−3) ÷ 6
s2008m [1.1K]

Answer:

(-162)/7 or -23 1/7 as mixed fraction

Step-by-step explanation:

Simplify the following:

(-36)/14 (-18) (-3)/6

Hint: | Express (-36)/14 (-18) (-3)/6 as a single fraction.

(-36)/14 (-18) (-3)/6 = (-36 (-18) (-3))/(14×6):

(-36 (-18) (-3))/(14×6)

Hint: | In (-36 (-18) (-3))/(14×6), divide -18 in the numerator by 6 in the denominator.

(-18)/6 = (6 (-3))/6 = -3:

(-36-3 (-3))/14

Hint: | In (-36 (-3) (-3))/14, the numbers -36 in the numerator and 14 in the denominator have gcd greater than one.

The gcd of -36 and 14 is 2, so (-36 (-3) (-3))/14 = ((2 (-18)) (-3) (-3))/(2×7) = 2/2×(-18 (-3) (-3))/7 = (-18 (-3) (-3))/7:

(-18 (-3) (-3))/7

Hint: | Multiply -18 and -3 together.

-18 (-3) = 54:

(54 (-3))/7

Hint: | Multiply 54 and -3 together.

54 (-3) = -162:

Answer:  (-162)/7

The mean value of 500 homes in a county is $225,000 and the standard deviation is $25,000. approximately how many of the homes i
dusya [7]

240 homes in the county are between $175,000 and $225,000.

The image attached is associated with this question and m in it refers to the mean value which is $225000 here and d refers to the standard deviation which is $25000 here.

Now since m= $225000

and $175000= $225000-$50000= $225000-(2* $25000)= m-2d

Thus, as per the image area covered between m and m-2d=  $225000

and $175000 is (34%+14%)of 500 homes= 68% of 500= 240 homes, is the answer.

A random variable X is said to follow a normal distribution if its parameters are mean and standard deviation. Every other distribution can be reduced to a normal distribution.
