\text{Hey there!}

\mathsf{What\ is\ \dfrac{7}{10}+\dfrac{1}{4}\ in\ simplest\ form?}

\text{First, look for the lowest common denominator (LCD) of the fractions.}\\\text{If you did the calculations correctly, you should've came up with 20 as}\\\text{your  LCD}

\mathsf{Here\ is\ how so: \dfrac{7\times2}{10\times2}+\dfrac{1\times5}{4\times5} = \ ?}

\mathsf{7\times2=14\leftarrow first\ numerator}\\\mathsf{10\times2=20\leftarrow first\ denominator}

\mathsf{1\times5=5\leftarrow second\ numerator}\\\mathsf{4\times5=20\leftarrow second\ denominator}

\mathsf{Your\ new\ equation\ SHOULD\ look\  like\ this: \dfrac{14}{20}+\dfrac{5}{20}}

\text{Since, your DENOMINATORS are ALIKE we can KEEP IT}

\mathsf{Which\ leaves\ us\ with\ the\ last\ step\ of\ the\ problem}

\mathsf{ \dfrac{14+5}{20}}}

\mathsf{14+5=19\leftarrow your\ new\ numerator}\\\\\mathsf{20 = 20\leftarrow your\ new\ denominator}

\boxed{\boxed{\bf{Answer: \mathsf{\dfrac{19}{20}}}}}\checkmark

\text{Good luck on your assignment and enjoy your day!}

Answer: 19/20

Step-by-step explanation:

7/10 turns into 14/20

1/4 turns into 5/20

14/20 + 5/20

14 + 5 over 20

= 19/20

19/20 is in simplest form.

<h3>Answer:   110 degrees</h3>

======================================================

Work Shown:

x = measure of minor arc CL

angle J = ( (far arc) - (near arc) )/2

angle J = ((red arc) - (yellow arc))/2

angle J = ( (minor arc CL) - (minor arc CK) )/2

35 = ( x - 40 )/2

35*2 = x-40

70 = x-40

x-40 = 70

x = 70+40

x = 110

Minor arc CL = 110 degrees

Three friends each have some ribbon. Carol has 54 inches of ribbon, Tino has 7.5 feet of ribbon, and Baxter has 3.5 yards of rib
Nastasia [14]
1 ft = 12 inches......1 yd = 36 inches

carol has 54 inches
Tino has 7.5 ft......7.5 * 12 = 90 inches
baxter has 3.5 yds......3.5 * 36 = 126 inches
for a total of : (54 + 90 + 126) = 270 inches total <===

1 ft = 12 inches....so 270 inches = 270/12 = 22.5 ft <==
1 yd = 36 inches..so 270 inches = 270/36 = 7.5 yds <==

A corporation with several thousand employees wants to estimate the mean commute time for all employees. They would like to cons
velikii [3]

Answer:

C.25

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

Which of the following is the smallest sample the company can take to achieve the desired margin or error?

This is n when \sigma = 10, M = 4

M = z*\frac{\sigma}{\sqrt{n}}

4 = 1.96*\frac{10}{\sqrt{n}}

4\sqrt{n} = 1.96*10

\sqrt{n} = \frac{1.96*10}{4}

(\sqrt{n})^{2} = (\frac{1.96*10}{4})^{2}

n = 24.01

We have to round up.

So the correct answer is:

C.25
