We are looking for the Zo score that corresponds to the 30th percentile.
 We use the table for the standard normal distribution.
 From P (Z <Zo) = 0.3 we search for Zo.
 Then we look in the table for the value of Zo that corresponds to 0.3.
 Hence, the approximate value is -0.53.
 The option is the third

Answer:

y=-2x+12

Step-by-step explanation:

This is an equation in slope-intercept form:

y=mx+b (where m is the slope and b is the y-intercept)

We are given the slope, -2.

y=-2x+b

We plug in the values (5,2):

2=(-2)*5+b

2=-10+b

b=12

The equation is:

y=-2x+12

I'm so confused please helpppppppp<br><br> How is C correct please show your work
777dan777 [17]

Answer:

Step-by-step explanation:

She makes $325 a week, so go to the 8th row, for weekly income of $300 to $400.  She claims 2 exemptions, so go to the third column labeled 2.  The value is 2.  That means the $2 is withheld from her paycheck on top of the 6.25% for FICA.  The total is therefore:

$2 + (0.0625) ($325)

$22.3125

Rounded to the nearest cent, that's $22.31.

Please help!!!!!!!!!!!!!!!!!!!!!!!!!! answer both
weeeeeb [17]

<u>Solution </u><u>1</u><u> </u><u>:</u><u>-</u>

Given expression ,

\implies 13^{\frac{3}{4}}

We know that, a^{\frac{m}{n}} = \sqrt[n]{a^m}

Therefore , this can be written as ,

\implies \sqrt[4]{13^3}

<u>Solution</u><u> </u><u>2</u><u>:</u><u>-</u>

Given expression ,

\implies \sqrt[3]{24^{10}}

We know that,a^{\frac{m}{n}} = \sqrt[n]{a^m}

Therefore, this can be written as ,

\implies 24^{\frac{10}{3}}

A rectangle with a length of 6 inches and a width of 1 foot has a perimeter of 14 inches.
Pachacha [2.7K]
The length is 6 inches.
The width is 1 foot = 12 inches.

The perimeter is  (6 + 12 + 6 + 12) = 36 inches (3 feet) .

"14 inches" is false.
