The Split Ends Salon orders 10 cases of hand-made hairbrushes.
r-ruslan [8.4K]

Answer:

it would take 65 hours to produce all of the order.

Step-by-step explanation:

1. you already would figure out that 26 hours=4 cases or 6.5 hours per case of hairbrushes.

2. You would figure out that 26+26 is 52 so 52 hours for 8 cases

3. Then you remember u have 8 cases of hairbrushes now. Set up a mental equation where you can solve in your mind: if I need 10 cases, but have figured out I only calculated 8, how much more would I still need to meet the order?

4. After mentally solving the hypothetical problem, you then would conclude you needed 2 more cases from 8 to equal 10.

5. you then divide 26 hours per 4 cases and you get 13 hours for 2 cases.

6. finally you multiply 26+26+13 which you would get 65 as the answer

What is the formula for the confidence interval? Then, define what each variable represents.
Alisiya [41]
The confidence interval for a <span>(1−α)%</span> confidence level is given by
<span>
(<span>θ0</span>−<span>Z<span>α/2 </span></span><span>σ/√n</span>, <span>θ0</span>+<span>Z<span>α/2 </span></span><span>σ/√n</span>)

</span><span>θ0</span> is the measured statistic, <span>Z<span>α/2</span></span> is the cutoff/critical value, and <span>σ/<span>√n</span></span> is the standard error. σ is the population standard deviation (if known) or can be estimated by a sample standard deviation. n is the sample size. The cutoff value depends on the test you wish to use, and <span>θ0</span><span> depends on the statistic you wish to estimate.</span>

Answer:

All but the second one

Step-by-step explanation:

The rule of a function is that you can't have the same x values in an expression. You can have multiple y values but not multiple x values.

Simplify the expression: show all ur steps/ wrk PLEASE,1+2x3-18/3+(5(2+2)]
Maurinko [17]
Ok let's do this*pops knuckles*



let's add the first side

1 + 2 \times 3 - 18
order of operations demands that we do multiplication first(P.E.M.D.A.S)

so
2 \times 3 = 6
now we can add the 1 from
1 + (6) - 18
into our six


6 + 1 = 7
now we substract

(7) - 18 =  - 11
now we have
- 11  \div 3 + (5(2 + 2))
now we focus on the
other side
3 + (5(2 + 2))
since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.
(5(2 + 2)) = (((5 \times 2) + (5 \times 2) = 20
now we have
3  + 20 = 23

(the three is from the original equation)

now we plug in our final numbers

- 11 \div 23
or
\frac{ - 11}{23}
I hope this helps
