Answer:

is it just 2 angles on straight line? if so, angle 7 is 130

Step-by-step explanation:

any 2 angles on one straight line must equal 180

180-50=130

strojnjashka [21]

Answer: Since 10° is less than 90, we can express this in terms of a co-function. cos(θ) = sin(90 - θ) cos(10) = sin(90 - 10) cos(10) = sin(80)

Step-by-step explanation: Note that cos10° is periodic: cos (10° + n × 360°) = cos 10 degrees, n . There are more formulas for the double angle (2 × 10°), half angle ((10/2)°) as well as the sum, difference and products of two angles such as 10° and β.

Answer please for x and y

notsponge [240]

Add the equations together:
12x-12x-11y-5y=40+88
you get
-16y=128
divide y=128/-16
y=-8

then plug-8 for y back into either equation.
12x-11(-8)=88
12x+88=88
12x=0
x=0

A certain type of concrete mix is designed to withstand 3000 pounds per square inch (psi) of pressure. The concrete is poured i

velikii [3]

Answer:

Step-by-step explanation:

Given the data representation of the strength of nine randomly selected casts (in psi) as 3960, 4090, 3200, 3100, 2940, 3830, 4090, 4040, 3780.

MEAN

Mean is the average of the samples

$\overline x = \frac{\sum Xi}{N}$

$\sum Xi$ is thw sum of the given data

N is the sample size

$\overline x$ is the mean

$\overline x = \frac{3960+4090+3200+3100+2940+3830+4090+4040+3780}{9}\\\\\overline x = \frac{33,030}{9}\\ \\\overline x = 3,670psi$

Hence the mean of the data is 3,670psi

MEDIAN

Median is the value at the middle of the data after rearrangement.

On rearranging in ascending order

2940, 3100, 3200, 3,780) 3,830 (3,960, 4040, 4090, 4090

It can be seen that the middle value is 3860. Hence the median of the data is 3860psi.

MODE

Mode is the most occurring data in the dataset. It is the data with the highest frequency. From the data, it can be seen that the only data occurring most (twice) is 4090, hence the modal value is 4090psi
