Answer:

The answer is k = -13.

Step-by-step explanation:

1) Subtract 6 from both sides.

[tex] - 7 - 6 = k[/tex]

2) Simplify -7-6 to -13.

[tex] - 13 = k[/tex]

3) Switch sides.

[tex]k = - 13[/tex]

Therefor, the answer would be k = -13.

Answer:

[tex]D = 7\sqrt 2[/tex]

Step-by-step explanation:

Given

[tex]A = (-3,-4)[/tex]

[tex]B = (4,3)[/tex]

Required

The distance between them

This is calculated as:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

So, we have:

[tex]D = \sqrt{(3-(-4))^2+(4-(-3))^2}[/tex]

[tex]D = \sqrt{7^2+7^2}[/tex]

[tex]D = \sqrt{2(7^2)}[/tex]

[tex]D = 7\sqrt 2[/tex]

Answer: A=450

Step-by-step explanation:

Answer:

[tex](a)[/tex]  [tex]P(M\ or\ P\ or\ C) = 1.307[/tex]

(b) See Explanation

Step-by-step explanation:

Given

[tex]P = 312[/tex] ---- Professionals,

[tex]M = 470[/tex] ----- Married persons,

[tex]C = 525[/tex] ---- College graduates,

[tex]PCG = 42[/tex]  ----- Professional college graduates,

[tex]MCG = 147[/tex] ----- Married college graduates,

[tex]MP = 86[/tex]  ---- Married professionals,

[tex]MPCG = 25[/tex] ---- Married professional college graduates

[tex]Total =1000[/tex]

Solving (a): P(M or P or C)

This is calculated as:

[tex]P(M\ or\ P\ or\ C) = P(M) + P(P) + P(C)[/tex]

[tex]P(M\ or\ P\ or\ C) = \frac{n(M) + n(P) + n(C)}{Total}[/tex]

[tex]P(M\ or\ P\ or\ C) = \frac{470 + 525 + 312}{1000}[/tex]

[tex]P(M\ or\ P\ or\ C) = \frac{1307}{1000}[/tex]

[tex]P(M\ or\ P\ or\ C) = 1.307[/tex]

(b) In probabilities, the probability of an event or collection of events must not exceed 1 and must not go below 0.

In (a) above, the calculated probability exceeds 1.

Because of this single reason, the collected data is incorrect

Answer:

15 cm

Step-by-step explanation:

Base x height / 2 = Area(of a triangle) =

3 x 10 / 2 =

15 cm

The solution is :  the area of the following triangle is, 15 cm².

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Here, we have,

given that,

4.2 cm

3 cm

10 cm

We know that,

area = bh/2

i.e. we get,

Base x height / 2

= Area(of a triangle)

substituting the values, we get,

= 3 x 10 / 2

= 15 cm²

Hence, The solution is :  the area of the following triangle is, 15 cm².

Questions:

a. The jet ski is for two persons and has turbo packs.

b. The jet ski is not for two persons but has turbo packs.

Answer:

[tex]P(P\ and\ T) = \frac{10}{29}[/tex]

[tex]P(P\ and\ T') = \frac{270}{841}[/tex]

Step-by-step explanation:

Given

[tex]n=29[/tex] --- Total

[tex]T = 14[/tex] --- Two person skis

[tex]P = 18[/tex] --- Turbo packs skis

[tex]P\ and\ T = 10[/tex] --- Two person ski and Turbo packs

Solving (a):

This is represented as: [tex]P(P\ and\ T)[/tex]

This is calculated as:

[tex]P(P\ and\ T) = \frac{n(P\ and\ T)}{n}[/tex]

[tex]P(P\ and\ T) = \frac{10}{29}[/tex]

Solving (a):

This is represented as: [tex]P(P\ and\ T')[/tex]

This is calculated as:

[tex]P(P\ and\ T') = P(P)\ and\ P(T')[/tex]

[tex]P(P\ and\ T') = P(P)\ *\ P(T')[/tex]

Using the complement rule, we have:

[tex]P(T') = 1 - P(T)[/tex]

The equation becomes:

[tex]P(P\ and\ T') = P(P)\ *\ [1 - P(T)][/tex]

[tex]P(P\ and\ T') = \frac{n(P)}{n}\ *\ [1 - \frac{n(T)}{n}][/tex]

[tex]P(P\ and\ T') = \frac{18}{29}\ *\ [1 - \frac{14}{29}][/tex]

[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{29-14}{29}[/tex]

[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{15}{29}[/tex]

[tex]P(P\ and\ T') = \frac{18*15}{29*29}[/tex]

[tex]P(P\ and\ T') = \frac{270}{841}[/tex]

Answer:

66

Step-by-step explanation:

first you find the area of the rectangle

5*12=60

then you find the area of the triangle

to find the length of the dotted line you need to subtract 9 from 12 which is 3

to find the length of the line adjacent to the dotted line you need to subtract 5 from 9 which is 4

use the triangle area formula 3*4*1/2=6

add the areas of the triangle and the rectangle 60+6=66

Answer:

The goal is $19,800.

Step-by-step explanation:

$16,770 is $1,230 less than %90 of the goal. If you add 16,770 and 1,230, you get 18,000. Then you have to multiply that by 1.10 to get it to the goal. That is how you get $19,800, which is the answer.

Answer:

78.5398

Step-by-step explanation:

Area of a circle:

a=[tex]\pi[/tex]r²

Radius is 10.

a=[tex]\pi[/tex]10²

a=[tex]\pi[/tex]100

a=314.15926

90° is one quarter of the circle, so multiply it by 0.25.

314.15926x0.25=78.5398

I don't know how many places the directions want it rounded to.  If it said to use 3.14 for pi, the answer would just be 78.5.

The required ratio of the unshaded square to the shaded square is 7 : 3.

Given that,
To determine the ratio of the number of unshaded squares to the number of shaded squares.​

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Number of shaded squares = 3
number of unshaded squares = 7
Required ratio = 7 / 3 = 7 : 3

Thus, the required ratio of the unshaded square to the shaded square is 7 : 3.
