Candice is preparing for her final exam in Statistics. She knows she needs an 74 out of 100 to earn an A overall in the course.
Salsk061 [2.6K]

Answer:

Hence the correct option is option b) Yes, the upper level of one standard deviation is 72.

A score of 74 is not within one standard deviation of the mean.

Step-by-step explanation:

Here the given details are,

Mean = 68  

SD = 4  

Distribution is normal.  

Z-score for x = 74 is given as below:  

Z = (X - mean)/SD\\Z = (74 - 68)/4\\Z = 1.5  

So, the score of 74 is 1.5 standard deviations from the mean.  

Mean + 1\timesSD = 68 + 1\times4 = 72Mean - 1\timesSD = 68 - 1\times4 = 64  

Therefore the score is not lies between 64 and 72.  

Yes, the upper level of one standard deviation is 72.

 A road has a 16.7% grade.<br>Why might we want to warn drivers of a grade like this?
never [62]
The higher the percentage, the steeper the grade and the steeper the hill. This warning is issued so drivers are more careful (otherwise they would probably get into more accidents).

A wire 22 cm long has a mass of 374 g. What is the mass of 13 cm of this wire?
taurus [48]

Answer:

<u>2</u><u>2</u><u>1</u><u> </u><u>g</u>

The up pinned pic is of inverse variation typed answer.. If u want word problem type answer here are the steps (EVEN IF THE STEPS ARE DIFFERENT ANSWERS REMAIN SAME)

Step-by-step explanation:

Mass of wire from 22cm = 374g

Mass of wire from 1 cm = 374÷22 = 17g

Mass of wire from 13 cm = 13×17 = <u>2</u><u>2</u><u>1</u><u> </u><u>g</u>

If x = y then 3x = 3y property of equality
Debora [2.8K]

Answer:

Multiplication property of equality

Step-by-step explanation:

The multiplication property of equality states that if x = 1, then you can multiply both sides by the same number and both sides will stay equal to each other. Therefore, if x = y, then you can multiply both sides by the 3 to make 3x = 3y and they will still be equal to each other.

I hope you find this helpful. :)

Write an explicit rule in function form for the sequence represented by the given terms.
hram777 [196]

Answer:

The general relation about a geoemtric sequence is

a_{n}=a_{1}r^{n-1}

For the first sequence, we have

3=a_{1}r^{5-1}

147=a_{1}r^{7-1}

Which is a system of equations. We can isolate a variable in the first equation to replace that expression into the second equation.

a_{1}=\frac{3}{r^{4} }

147=\frac{3}{r^{4}  }r^{6}

r^{2}=\frac{147}{3}\\  r=\sqrt[2]{49}\\r=7

Now, we replace this value to find the other one

3=a_{1}(7)^{4}\\ a_{1}=\frac{3}{2401}

Therefore, the explicit rule function is

a_{n}=\frac{3}{2401}  \times (7)^{n-1}

Now, we use the same process for the second sequence.

10=a_{1}r^{3-1}  \\a_{1}=\frac{10}{r^{2} }

The second equation is

1440=a_{1}r^{5-1}\\a_{1}=\frac{1440}{r^{4} }

Now, we solve the following expression

\frac{10}{r^{2} }=\frac{1440}{r^{4} }

We solve for r

\frac{r^{4} }{r^{2} }=\frac{1440}{10}\\r^{2}=144\\ r=\sqrt{144} \\r=12

Then

a_{1}=\frac{10}{(12)^{2} }  =\frac{10}{144}=\frac{5}{72}

Therefore, the function that models the second sequence is

a_{n}=\frac{5}{72} \times (12)^{n-1}

Notice that a_{n} is the dependent variable and n is the independent variable.
