What Is The Length Of Of BC? With Work Pls Help

Answers

Answer 1

Answer:

31

Step-by-step explanation:

Assuming the drawing is to scale

The triangle is equilateral according to measure, So the measure of angles A, B and C are the same and the lengths of sides AB, BC and BA are equalThere is very little information to go off, so the measurements are done with a ruler etc.With that in mind, this means AC=BC, ergo [tex]6x-5=4x+7[/tex] So, [tex]6x-4x=7+5[/tex] then [tex]x=6[/tex] Plugging that back into BC, we have [tex]4(6)+7=24+7=31[/tex]

Find the sides of the triangle. Perimeter =102

Answers

Here is the set up:

Side 1 is 4x.

Side 2 is 5x + 3

Side 3 is 5x + 1

The perimeter is 102.

Perimeter = side 1 + side 2 + side 3

102 = 4x + 5x + 3 + 5x + 1

102 = 14x + 4

Hello!

0.5 (5 - 7x) = 8 - (4x+6)
2.5 - 3.5x = 8 - 4x + 6
2.5 - 3.5x = 2 - 4x
-3.5x + 4x = 2 - 2.5
0.5x = -0.5
X = -1

Write the equation in point-slope form of a line that has a slope of m=2 and the point (x, y) = (6,8).
(Remember: point-slope form is y-y1 = m(x -x1)
where (x1, y1) is a point and m is the slope.)

A line y = mx +b passes through point (8, – 6) and is parallel to y = -x +4.
What is the value of b?

Answers

Answer:

b = 2

Step-by-step explanation:

Since the two lines are parallel, their slope is the same.

Slope = -1

The function: y = -x + b

Plug in the coordinate values to solve for b.

-6 = -8 + b

-6 + 8 = b

2 = b

b = 2

log₃(-2 tan(x)) = 1/2

Write both sides as powers of 3, and use the property [tex]b^{\log_ba}=a[/tex]:

[tex]3^{\log_3(-2\tan x)}=3^{\frac12}[/tex]

-2 tan(x) = √3

Then solve for x :

tan(x) = -√3 / 2

x = arctan(-√3 / 2) + nπ

x = -arctan(√3 / 2) + nπ

Some parts of California are particularl earthquake prone. Suppose in one metropolitan area, 40% of all homeowners are insured against earthquake damage. Four homeowners are selected at random. Let X denote the number among the four who have earthquake insurance. Assume that the event of each homeowner having or not having insurance is independent.

Required:
a. Find the probability mass function of X?
b. What is the most likely value for X?
c. What is the probability that at least two of the four selected have earthquake insurance?

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Percentage of insured home owners = 40% p = 0.4

Selecting 4 home owners (x) ;

x = 0, 1, 2, 3, 4

Using bernoulli;

nCx * p^x * (1 - p)^(n-x)

For X = 0

4C0 * 0.4^0 * 0.6^(4-0) = 0.1296

X = 1

4C1 * 0.4^1 * 0.6^(4-1) = 0.3456

X = 2

4C2 * 0.4^2 * 0.6^(4-2) = 0.3456

X = 3

4C3 * 0.4^3 * 0.6^(4-3) = 0.1536

X = 4

4C4 * 0.4^4 * 0.6^(4-4) = 0.0256

B.) The most likely value for X are 1 and 2 with probabilities of 0.3456 respectively.

C.) probability that atleast 2 of the 4 selected have earthquake insurance ;

P(X ≥ 2) = p(2) + p(3) + p(4)

P(X ≥ 2) = 0.3456 + 0.1536 + 0.0256

P(X ≥ 2) = 0.5248
