Answer:
a) x= 5 or x= -3
b) x = -4 + 
or -4 -
Step-by-step explanation:
a) 
- 2x - 15 =0
x = 
or 
x= 5 or x=-3
b) + 8x - 10 =0
x = 
or 
x = -4 + or -4 -
Answer:
e. Two-sample t-test.
Step-by-step explanation:
This is simply because you only have interval level of measure and you are comparing two populations.
Moreso, this hypothesis test is used to determine questions related to the mean in situations where data is collected from two random data samples. The two sample T-test is often used for evaluating the means of two variables or distinct groups, providing information as to whether the means between the two populations differs. It also can be used to compare the responses of males and females who have each received different treatment within an experiment.
Answer:
A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .
A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .
If a line is horizontal the slope is zero. This is a constant function.
If a line is vertical the slope is undefined (see below).
Answer:
35 kgs.
Step-by-step explanation:

Answer:
answer is 3 or 50 degrees
Step-by-step explanation:
put angle 35 degrees between F and E and then add 5 degrees to get 40
then add the 90 degrees to get 130
then subtract 130 from 180 to get 50 degress
