Answer:

85.5

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). When there is an even number of terms, add the two middle terms and divide by 2.

Step-by-step explanation:

79, 83, 88, 93

83 + 88 = 171

171 ÷ 2 = 85.5

konstantin123 [22]

Answer:

I think that the required options are wrong.

Answer is given below with explanations.

mZCBD = 41 degrees

Step-by-step explanation:

from \: the \:  \: above \: mentioned \: diagram \\ we \: can \: say \: that \:  \\( angle \: ABD) + (angle \: DBC) = 68 \\ given \: that \:  \: angle \: ABD = 2x + 5 \\ and \: \:  angle \: CBD = 3x + 8 \\ on \: substituting \: the \: values \\ (2x + 5) + (3x + 8) = 68 \\ 5x + 13 = 68 \\ 5x = 68 - 13 \\ 5x = 55 \\ x =  \frac{55}{5}  \\ x = 11 \\ angle \: CBD = 3x + 8 \\  \:  \:  = 3(11) + 8 \\  \:  \:  = 33 + 8 \\  \:  \:  angle \: CBD= 41

A rectangle has a perimeter of 54 meters and a height of 14 meters. What is the length of the base? Please help!!
Ksivusya [100]
13 because if the height is 14 you would subtract 28 because there’s two sides. Then you would get 26, divide that by 2 and get 13 for the base. Idk if it makes sense
