Answer: d. Do not reject the null hypothesis when it is actually false.
Step-by-step explanation:
A Type II error occurs when we do not reject the null hypothesis when the alternative hypothesis is actually the true statement.
i.e. actually null hypothesis was false but get not rejection.
It is also known as Beta error.
Therefore , the correct answer is A Type II error occurs when we <u>Do not reject the null hypothesis when it is actually false</u> .
Hence, the correct answer : d. Do not reject the null hypothesis when it is actually false
Answer: Third option
Step-by-step explanation:
A unit vector is a vector that has magnitude 1.
To find a unit vector in the direction of the vector v we must first calculate the magnitude of v and then divide the vector v by its magnitude
The vector v is:
v = -5i - 2j
The magnitude of the vector is:
Now we divide the vector v by its magnitude
Simplifying we have to
Answer:
2
Step-by-step explanation:
m = 2-(-2)/-2-(-4)
m = 4/2
m = 2
Step-by-step explanation:
15t + 30 = 20t | -15t
30 = 5t
t = 30/5 = 6
20 + 5t = -6t + 86 | + 6t
20 + 11t = 86 | -20
11t = 66
t = 6
18t + 20 = 24t + 50 | -18t
20 = 6t + 50 | -50
-30 = 6t
t = -30/6 = -5
18t - 2 = 10t + 54 | -10t
8t - 2 = 54 | +2
8t = 56
t = 56/8 = 7
7t - 5 = 15t + 91 | -7t
-5 = 8t + 91 | -91
-96 = 8t
t = -96/8 = -12
Answer:
-1 >x
Step-by-step explanation:
-4(7+6x)<-2(x-6)
-28-24x<2(x-6)
-28-24x<-2x-6
+6. +6
-22-24x<-2x
+24x +24x
-22 < 22x.
-22÷-22=1 that canceled out
+22÷-22= -1
-1>x. because we divided by a negative the inequality switched.
Hope this helped
