(10x+5)4 = 30x + 3x + 6x +30

40x + 20 = 39x + 30

X = 10

perimeter of the square= 420
perimeter of the triangle= 420

A​ town’s January high temperatures average 36 degrees​ (F) with a standard deviation of 10 degrees while in July the mean high
n200080 [17]

Answer:

55 degrees is more unusual in July as it is away from mean temperature as compared to January.

Step-by-step explanation:

We are given the following information in the question:

January:

Mean, μ = 36 degrees

Standard Deviation, σ = 10 degrees

July:

Mean, μ = 74 degrees

Standard Deviation, σ = 8 degrees

We calculate z scores corresponding to x = 55.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

January:

z_{score} = \displaystyle\frac{55-36}{10} = 1.9

July:

z_{score} = \displaystyle\frac{55-74}{8} = -2.375

Thus, 55 degrees is more unusual in July as it is away from mean temperature as compared to January.

-24+2w - 18

Subtract -24 -18

2w - 42
