Answer:
2471.81
Step-by-step explanation:
Let I be the interest, r the annual rate and P the principal. Then:
I = P(r)^2 = 5460
I = P(r)^4 = 12060.6
so r^2 = P(r)^4 / P(r)^2 = 12060.6/5460
r^2 = 2.2089
r = 1.486
So P(r)^2 = P* 2.2089 = 5460
P = 5460 / 2.2089 = 2471.81.

Suppose that 60\%60%60, percent of adults in district A support a new ballot measure, while 45\%45%45, percent of adults in district B support the same measure. Pollsters take an SRS of 200200200 adults from district A and a separate SRS of 100100100 adults from district B to see the difference between the sample proportions (\hat{p}_\text{A}-\hat{p}_\text{B})( p ^ A − p ^ B )left parenthesis, p, with, hat, on top, start subscript, start text, A, end text, end subscript, minus, p, with, hat, on top, start subscript, start text, B, end text, end subscript, right parenthesis.

Answer:it’s B (120 succes and 80 failures for khan academy)
Step-by-step explanation: trust me
The shape of the sampling distribution of [tex]\hat{p}_\text{A}-\hat{p}_\text{B}[/tex] is approximately normal because the number of success in district A is 120
How to determine the shape of the distribution?The given parameters are:
Proportion of adults in district A = 60%Proportion of adults in district B = 45%Sample size of A, n = 200Sample size of B, n = 100In the sample size of 200, the number of adults that support a new ballot measure is:
Success = 60% * 200
Success = 120
Those that oppose is
Failure = 200 - 120
Failure = 80
If 45% supports a new ballot measure in district B, then 55% do not support
The difference between those that support and do not support is:
(55% - 45%) * 100 = 10
Hence, the sampling distribution of [tex]\hat{p}_\text{A}-\hat{p}_\text{B}[/tex] is approximately normal

A tool box has the dimensions of 10 in by 7 in by 3 in. If Deena plans to double all three dimensions to build a larger tool box, she believes she would double the volume of the tool box. Is she correct?
Answer:
She will not be correct
Step-by-step explanation:
Given data
Length=10in
Width=7in
Height=3in
The volume of the toolbox
V=10*7*3
V=210 in^3
Let us double the volume and see
2V= 210*2
=420 in^3
Let us also double the individual dimensions
Length=20
Width=14in
Height=6in
V= 20*14*6
V=1680 in^3
Hence the volume will be different, she will not be correct

Step-by-step explanation:
In slope intercept y=mx+b if the slope is 3/4 and the -y intercept is -2
Answer:
y = [tex]\frac{3}{4}[/tex] x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = [tex]\frac{3}{4}[/tex] and b = - 2 , then
y = [tex]\frac{3}{4}[/tex] x - 2 ← equation of line

$8,315 in account $315 interest
$9,216 in account $1,261 interest
Answer:
$9,216 in account $1,261 interest.
Step-by-step explanation:
The compound interest is given by:
[tex]a = p(1 + \frac{r}{n})^{nt} [/tex]
P = Principal
r = rate
n = Number of times interest is compounded per unit t
t = time
so:
[tex]a = 8000(1 + \frac{0.05}{1} ) ^{1 .3} \\ a = 9261[/tex]
therefore, the answer is:
$9,216 in account $1,261 interest

A pizza pan is removed at 9:00 PM from an oven whose temperature is fixed at 425°F in a room that is constant 74°F. After 5 minutes, the pizza pan is at 300 °F
A) at what time is the temperature of the pan 130°F ?
B) determine the time that needs to elapse before the pan is 180°
Answer:
9:11:48 p.m
9.8 minutes
Step-by-step explanation:
We Obtian the slope of the relation :
Slope = Rise / Run
(0, 425) ; (5, 300)
x2 = 0 ; y2 = 425 ; x1 = 5 ; y1 = 300
(425 - 300) / (0 - 5)
125 / - 5
= - 25
The intercept :
y = mx + c
425 = - 25(0) + c
425 = 0 + c
c = 425
The equation becomes :
y = - 25x + 425
Temperature at 130
130 = - 25x + 425
130 - 425 = - 25x
-295 = - 25x
x = 11.8
9:00 + 11.8 = 9:11:48 p.m
B.)
180 = - 25x + 425
180 - 425 = - 25x
-245 = - 25x
x = 9.8 minutes

Leslie has a watering can that holds 1 liter of water. She uses 250 milliliters of water on each of her plants. How many plants can she water? *remember 1L = 1000 milliliters of water
Answer:
4 plants
Step-by-step explanation:
convert the capacity of the watering can to millimeters
1L = 1000 milliliters
1 x 1000 = 1000 millimeters
Plants that can be watered = capacity of the watering can / amount of water a plant needs
1000 / 250 = 4 plants
