Answer:
h = -5
Step-by-step explanation:
1) Subtract 7th from both sides
6h = 7h + 5
6h - 7h= 7h + 5 - 7h
2) Simplify
- Combine like terms
6h - 7h = 7h + 5 - 7h
-h = 7h + 5 - 7h
- Combine like terms
-h = 7h + 5 - 7h
-h = 5
3) Divide both sides by the same factor
-h = 5
-h/-1 = 5/-1
4) Simplify
Cancel terms that are in both the numerator and denominator
h/-1 = 5/-1
h = 5/-1
Divide the numbers
h = 5/-1
h = -5
Answer:
The mean weight is not greater than 16 ounces
Step-by-step explanation:
Null hypothesis: Mean weight is greater than 16 ounces
Alternate hypothesis: Mean weight is not greater than 16 ounces.
Sample mean= 16.04 ounces
Assumed mean= 16 ounces
Significance level = 0.05
Sample standard deviation = 0.08 ounces
Number of samples= 35
To test the claim about the mean, Z = (sample mean - assumed mean) ÷ (standard deviation÷ √number of samples)
Z = (16.04 - 16) ÷ (0.08 ÷ √35)
Z = 0.04 ÷ (0.08 ÷ 5.92)
Z= 0.04 ÷ 0.014 = 2.86
Z = 2.86
It is a one-tailed test, the critical region is an area of 0.05 (the significance level). The critical value of the critical region is 1.64
Since the computed Z 2.86 is greater than the critical value 1.64, the null hypothesis is rejected.
Conclusion
The mean weight is not greater than 16 ounces
10*0.2=2 When you are multiplying a decimal by 10 you just take off the decimal and you have the answer 2
The x intercept is -3, and the y intercept is -2
Step-by-step explanation:
The equation given is 4x+6y= -12
Rewrite the equation in slope intercept form of y=mx +c where c is the y intercept
y=mx+c
6y=-4x-12
y= -4/6 x -12/6
y=-2/3x -2
c= -2
To get x intercept replace value of y in the equation with 0;
y= -2/3 x -2
0= -2/3 x -2
2= -2/3 x
2*3=-2x
6=-2x
6/-2 =x
-3 =x
x intercept is -3
