Answer:

4.43 * 10 ^-2

Step-by-step explanation:

.0443

Move the decimal 2 places to the right

4.43 * 10 ^b

The b is 2 since we moved it 2 places, to the right means we make it negative

4.43 * 10 ^-2

Answer:

Step-by-step explanation:

mean: equal for both data sets

median: Greater for data set A

Range: Greater for data set B

Answer:

4x + 5 = 29

Step-by-step explanation:

x = # of coins in pocket, and you have 4 times that much. Add five to that, and you have a total of 29.

Answer:

4x+5=29

Step-by-step explanation:

let x=the # of coins in my pocket

4 times the number of coins in my pocket plus 5 more is 29 =

4x+5=29

Step-by-step explanation:

because it is not a linear equation

Answer:

$191.70

Step-by-step explanation:

total amount spent = cost of medicine + cost of tax + cost of shipping

cost of tax = 0.05 x $180 = $9

cost of shipping 0.015 x $180 = $2.70

total cost = $180 + $9 + 2.70 = $191.70

c. 40.32%

Step-by-step explanation:

Answer:

A.) Black eyed beans = at least 3 ; Red beans = atleast 4 ; Lima beans = atleast 5

B.) Red and Lima beans = 5 each ; Black eyed beans = 8

C.) Lima beans = 4 ; Black eyed beans = 2 ; Red beans = 2

Step-by-step explanation:

Let :

Black eyed beans = x

Red beans = x + 1

Lima beans = x + 1 +1 = x + 2

Total beans is atleast 12

x + (x +1) + (x + 2) ≥ 12

x + x + 1 + x + 2 ≥ 12

3x + 3 ≥ 12

3x ≥ 9

x ≥ 3

Black eyed beans = at least 3

Red beans = atleast 4

Lima beans = atleast 5

B.)

Same number of Red and Lima beans

Black eyed beans is 3 more than red beans

Total beans = 18

Red and Lima = x + x

Black eyed beans = x + 3

x + x + x + 3 = 18

3x + 3 = 18

3x = 18 - 3

3x = 15

x = 5

Red and Lima beans = 5 each

Black eyed beans = 3 + 5 = 8

C.)

Total beans in salad = x

Number of red beans = 2

Lima beans = 2 * 2 = 4

Lima beans = 1/2 of x ; x/2

4 = x /2

8 = x = total beans in salad

Red + lima + black eyed = 8

2 + 4 + black-eyed = 8

Black eyed beans = 8 - 6 = 2

Lima beans = 4

Black eyed beans = 2

Red beans = 2

Answer:

D). 6 3/4

Step-by-step explanation:

Given,

The three eggs with the heaviest weights are;

[tex]2\frac{1}{2}[/tex] ounces

[tex]2\frac{1}{4}[/tex] ounces, &

2 ounces

To find,

The total weight of the three heaviest eggs = [tex]2\frac{1}{2}[/tex] ounces + [tex]2\frac{1}{4}[/tex] ounces + 2 ounces

= 5/2 + 9/4 + 2/1

Taking the L.C.M. of 2, 4, and 1,

= 10/4 + 9/4 + 8/4

= (10 + 9 + 8)/4

= 27/4 or 6 3/4

Answer:

y = -1/3x -3

Step-by-step explanation:

Lines

Perpendicular lines have negative reciprocal slopes. To find the line, convert the slope of q and substitute it with (6, -5) into point-slope form.

y = 3x + 5 is q. It has a slope of 3. So, p will have a slope of -1/3.

y - y1 = m ( x - x1)

y - (-5) = -1/3 ( x - 6)

y + 5 = - 1/3x + 2

y = -1/3x - 3

Answer:

the ratio of apples to oranges is 4 to 3

Answer:

Confidence interval is 0.7 ≤ p ≤ 0.8

The margin of error is 7.1 %

Step-by-step explanation:

We have to calculate a 98% confidence interval for the proportion.

The sample proportion is p=0.75.

The standard error of the proportion is:

Here we have, the proportion or point estimate given by

= 150/200 = 0.75

Sample size, n = 200

The formula for confidence interval, CI, given a proportion, is;

At 98% z = ±2.326348

Plugging in the values of, , z and n we get;

CI = 0.6787704 ≤ p ≤ 0.8212296

To one decimal place, we have

CI = 0.7 ≤ p ≤ 0.8

Answer:

1, p = -0.5

Step-by-step explanation:

2(p+5) = 4 - 10p

2p+10 = 4 - 10p

2p + 10p = 4 - 10

12p = -6

p = -6/12

p = -0.5

2(-0.5+5) = 4 - 10(-0.5)

-1 + 10 = 4 + 5

Step-by-step explanation:

Answer:

The length of the side DE is approximately 541.3 feet long.

Step-by-step explanation:

There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{x} =\frac{sin(10^{o})}{94}[/tex] ⇒ [tex]\frac{x}{sin(90^{o})} =\frac{94}{sin(10^{o})}[/tex] ⇒ [tex]x = \frac{94*sin(90^{o})}{sin(10^o)}[/tex] ⇒ [tex]x=541.3ft.[/tex]
