Answer: The answers is (A) and (B)
Step-by-step explanation: We are to select the slope and y-intercept of the linear function that is graphed to the left.
We know that the equation of a straight line in slope-intercept form is given by
where 'm' is the slope and 'c' is the y-intercept of the line.
Also, a straight line with a positive slope (m>0) rises from left to right whereas a line with a negative slope (m < 0) falls from right to left.
Option (A) is
Since 'm' is negative, so the function is graphed to the left.
Option (B) is
Option (C) is
Since 'm' is positive, so the function is graphed to the right.
Option (D) is
Thus, (A) and (B) are the correct options.
Answer:
1.) mean
2.) H0 : μ = 64
3.) 0.0028
4) Yes
Step-by-step explanation:
Null hypothesis ; H0 : μ = 64
Alternative hypothesis ; H1 : μ < 64
From the data Given :
70; 45; 55; 60; 65; 55; 55; 60; 50; 55
Using calculator :
Xbar = 57
Sample size, n = 10
Standard deviation, s = 7.14
Test statistic :
(xbar - μ) ÷ s/sqrt(n)
(57 - 64) ÷ 8 / sqrt(10)
Test statistic = - 2.77
Pvalue = (Z < - 2.77) = 0.0028 ( Z probability calculator)
α = 10% = 0.1
Reject H0 ; if P < α
Here,
P < α ; Hence, we reject the null
seems to easy to be true but the answer is 7/12 cause it's a fraction and it can't be simplified
The opposite of 12 is -12.
-12, -11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
All you have to do is do the negative version of that same original number.
