Answer:
For this case we know that the confidence level is 89.48% or 0.8948 and the significance would be: 
and the value of 
Now we need to find a quantile in the normal standard distribution who accumulate 0.0526 of the area on each tail of the normal standard distribution and we got:
And we can use the following excel code for example:
"=NORM.INV(0.0526,0,1)"

Answer:
24
Step-by-step explanation:
- Negative × negative = positive
- -6 × -4 = 24
I hope this helps!
For this case, the first thing we must do is define variables.
We have then:
C: number of cans
B: number of bottles
We now write the expression that represents the total amount she receives:
0.10B + 0.05C
Answer:
The expression that represents the amount, in cents, that the center pays her is:
0.10B + 0.05C
Cost of tape: 4.95
no. of tape : x
budget : 37.85
4.95x < 37.85
+++
4.95x < 37.85
<u>÷4.95 ÷4.95</u>
x < 7.65
* you have to buy tapes that are less than 7.65
Assuming you bought 7 tapes.
4.95x < 37.85
4.95(7) < 37.85
34.65 < 37.85 *inequality is correct
If you buy more than 7 tapes, then, the cost of the tapes will be more than your budget. making the inequality incorrect.
Answer:
Answer:y = 1/4x -8Step-by-step explanation:First find the slope of the linex-4y =3Subtract x from each sidex-4y -x = -x+3-4y = -x+3Divide each side by -4-4y/-4 = -x/-4 +3/-4y = 1/4 x -3/4This is in the form y= mx+b where the slope is m and the y intercept is bThe slope is 1/4We want the same slopey = 1/4x +bwe know the y intercept is -8y = 1/4x -8.
