= 7 (a² + b²) (a² - b²)

Answer:

40

Step-by-step explanation:

let L be lisa's hit and J be jenny's

given that

L+J = 82 and

L = J+2

equate the two together

J+2+J=82

2J = 82-2

J= 80/2

J=40

The probability of selecting a shower gel given item is scented must be the same as grabbing shower gel which is 42%.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Juanita has a storage closet at her shop with extra bottles of lotion and shower gel, some are scented and some are unscented.

If she reaches into the closet and grabs a bottle without looking, she has a 42% chance of grabbing a bottle of shower gel.

For the events "shower gel" and "scented" to be independent.

P(A|B) = P(A)

P(B|A) = P(B)

P(A∩B) = P(A) × P(B)

We know that the probability she selects a shower gel is 42%. Let this event be A. Then we have

P(shower | scented) = P(shower gel) = 42%

This must be true for the events to be independent.

The sector is a part of the circle. Then the area of the sector will be 161 square centimeters.

It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The central angle of π/3 radians and a radius of 12.4 m.

Then the area of the sector will be given as

[tex]\rm Area\ of\ sector = \dfrac{\theta}{2\pi} \ \pi r^2\\\\\\Area\ of\ sector = \dfrac{\pi / 3}{\pi } *\pi * 12.4^2 \\\\\\Area\ of\ sector = 161.01 \approx 161[/tex]

Answer:

100001

Step-by-step explanation:

First, convert the three numbers to base 10. 1111=15, 1101=13, and 101=5. Now, add the numbers up in base ten. 15+13+5=33. Lastly, convert 33 to base 2. 33=100001 in base 2.

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

Work Shown:

angle A = angle B

2x+3 = 3x-5

3+5 = 3x-2x

8 = x

x = 8

angle A = 2x+3

angle A = 2*8+3

angle A = 16+3

angle A = 19

angle B = 3x-5

angle B = 3*8-5

angle B = 24-5

angle B = 19

Both angles are the same measure (19), which confirms our answer.

Answer:

X=8

Step-by-step explanation:

2x+3=3x-5. subtract 2x from both sides

3=x-5.  add 5 to both sides

3+5=x

Answer:

∠B = 58°

Step-by-step explanation:

∠A and ∠B are complementary.

-> ∠A + ∠B = 90°

-> 32° + ∠B = 90°

-> ∠B = 90° - 32°

-> ∠B = 58°

Answer:

<B = 58

Step-by-step explanation:

complementary angles are angles that sum up to 90°.

If A and B are angle when added will form 90°, to find B we follow the following steps

A + B = 90

if A = 32°,

32 + B = 90

collect like terms

B = 90 - 32

B = 58

that means

32 + 58 = 90

B = 58

Answer:

18 hours

Step-by-step explanation:

$108 = 9 hours

$216 = x hours

we want to get to $216 from the original equation. one thing we can do to get there is to figure out what we need to multiply 108 by to get 216. to figure this out, we can calculate 216/108 = 2.

therefore, we can multiply both sides of the original equation by 2 to get

$216 = 9 * 2 hours = 18 hours as our answer

She made $121000.

Step-by-step explanation:

The money the agent sold was:

4*175000=700000 (dollars)

but she only gets 13% of this, so she earned:

700000*0.13=91000 (dollars)

She also makes $30000 per year, so the total income she earned was:

Explanation:

The given equation is

4x^2 - 3x + 1 = 0

Compare this to the general quadratic

ax^2 + bx + c = 0

to find that a = 4, b = -3, c = 1.

Plug those values into the discriminant formula below.

d = b^2 - 4ac

d = (-3)^2 - 4*4*1

d = 9 - 16

d = -7

Then recall that...

We see that d = -7 fits with the third option highlighted above.

b = -2.7

Step-by-step explanation:

Isolate the variable, b

-5 = b - 2.3

add 2.3 to both sides (to isolate variable b)

-5 + 2.3 = b - 2.3 + 2.3

-2.7 = b + 0

-2.7 = b

Check work:

-5 = -2.7 - 2.3

-5 = -5

In the three-cell model of the general circulation, areas of surface low pressure should be found at the equator and 60° latitude.

In any environment, geographically speaking, the place with the lowest relative pressure is called the surface low-pressure center.

Surface low-pressure centers are created when the atmospheric circulation of air  (vertically) reduces a minuscule amount of atmosphere from a geographical region.

The missing values for the given two-way table are shown in the image attached below (see attachment).

A two-way table can be described as table that shows the frequencies of two categorical variables in rows and columns respectively.

To find the missing values in the two-way table that is given, simply subtract a known value from the corresponding given total of a row or column.

Thus:

First row total for print and electronics = 33 + 24 = 57

Second row for electronics = 48 - 24 = 24

Second row total for print and electronics = 32 + 24 = 56

Column total for print = 33 + 32 = 65

Third column for grand total = 57 + 56 = 113
