Answer:
See explanation
Step-by-step explanation:
Solution:-
- The researcher claims :
" the average annual salary of part-time community college instructors is at least $45,000 "
- We will extract the claim made by the researcher to be the Null hypothesis:
Null Hypothesis : μ ≥ $45,000
- Any statement otherwise, or point of rejection criteria will denote the Alternate hypothesis that disbands the claim that:
" the average annual salary of part-time community college instructors is less than $45,000 " :
Alternate Hypothesis : μ < $45,000
- This type of test with a sample size of n = 25 < 30 and population standard deviation is also not given hints the use t-test statistics and t-critical value reject the claim.
Lower tail - one sample - T-test.
Answer:
24 and 25
Step-by-step explanation:
From given, we have,
7 square = 49
Let the first positive number be = x
And the second consecutive positive number is = x+1
x + (x + 1) = 49
2x + 1 = 49
2x = 49 - 1
2x = 48
x = 24
the first number x = 24
the second consecutive number x+1 = 24 + 1 = 25
Thus, 7 square = 24 + 25 (the sum of two consecutive positive numbers.)
Step-by-step explanation:
8, 12(3-x)=48
36-12x=48
-12x=48-36
-12x=12 both side divideos by -12
-12x/-12=12/-12
x= 1
9, x/7=4.5 cris cross
x=31.5
10,5(x-3)=45
5x-15=45
5x=45+15
5x=60 both side divided by 5
5x/5=60/5
x=12
11,-3(x-3)=45
-3x+3=45
-3x=45-3
-3x=42 both side divided by -3
-3x/-3=42/-3
x=14
12,14y-8=13
14y=13+8
14y=21 both side divided by 14
14y/14=21/14
y=1.5
13,3m=5m-8/5
3m-5m=-8/5
-2m=-8/5 cris cross
-10m=-8 both side divided by -10
-10m/-10=-8/-10
x=0.8
