Answer: The value of x is equal to 9.
Step-by-step explanation:
To start, we need to perform the distributive property.
5(-2 + x) = 5 * -2 + 5 * x = -10 + 5x.
Now we have -10 + 5x = 35.
So next we need to isolate 5x by adding 10 to each side of the equation.
-10 + 5x = 35 + 10 = 5x = 45.
The last step is to divide each side by 5.
5x/5 = 45/5.
And the final answer is x = 9.
You can also plug in 9 into the original equation.
5(-2 + 9) = 35.
5(7) = 35.
35 = 35.
The person with the 5 gets 30 and the person with 4 gets 24
4 5/9 this is the answer to your question
Answer:
3040cm
Step-by-step explanation:
you simply multiply 10 by 19 to get 190 than do 190 times 16 where u would go 6 times 0 =0 6 times 9 =54 leave the 4 carry the 5 than 6 times 1 is 6 but add the 5 to get 1140 than for the 1 simply put a placeholder 0 than just put 190 since you're multiplying by one to get 3040
Answer:
The confidence interval is from 69.82 o 82.18
Step-by-step explanation:
Using this formula X ± Z (s/√n)
Where
X = 76 --------------------------Mean
S = Standard Deviation
If Variance = 144
S = √144
S = 12
n = 25 ----------------------------------Number of observation
Z = 2.576 ------------------------------The chosen Z-value from the confidence table below
Confidence Interval || Z
80%. || 1.282
85% || 1.440
90%. || 1.645
95%. || 1.960
99%. || 2.576
99.5%. || 2.807
99.9%. || 3.291
Substituting these values in the formula
Confidence Interval (CI) = 76 ± 2.576 (12/√25)
CI = 76 ± 2.576(12/5)
CI = 76 ± 2.576(2.4)
CI = 76 ± 6.1824
CI = 76 + 6.1824 ~ 76 - 6.1824
CI = 82.1824 ~ 69.8176
CI = 82.18 ~ 69.82
In other words the confidence interval is from 69.8176 to 82.1824
