Answer:
Step-by-step explanation:
Sum of all the angles of a triangle = 180°
∠A + ∠B + ∠C = 180°
48 + ∠B + 56 = 180
∠B + 104 = 180
∠B = 180 - 104
∠B = 76°
Answer:
y = -3/4x -4
Step-by-step explanation:
3x+4y=-16
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
Subtract 3x from each side
3x -3x+4y=-3x-16
4y = -3x-16
Divide each side by 4
4y/4 = -3x/4 - 16/4
y = -3/4x -4
Expanded form is the form of writing numbers in addition. Example: 653 would be 600+50+3 in expanded form. .37 using powers would be 37×10^-2 .
In expanded form, we just need to expand the 37 because it is the only one with 2 different places without a 0 in either one.
Answer: 30+7×10^-2 would be the expanded form of .37 using powers of 10.
Answer:
false

Answer, Step-by-step explanation:
According to the exercise, we evaluate the delivery time of a courier company and we will hypothesize the best case with a sample size of 10, which is:
Small sample T test for single mean
The hypothesis that we will develop will be the following:
null hypothesis = mu> = 6
hypothesis alternativa: <6
