Use the following table to determine P(X>4).
STatiana [176]

Answer:

0.11

Step-by-step explanation:

To get the probability above, we simply look for the events greater than 4, then add their probabilities

That is;

P(5) + P(6) + P(7)

So the probability in this case will be;

0.07 + 0.03 + 0.01 = 0.11

1. A point on the ground is 50 feet from my house. The angle of elevation to the top of the house is 48 Find the height of the h
Georgia [21]

Answer:

(1)55.5 feet

(2)7.5 feet

Step-by-step explanation:

<u>Question 1</u>

The diagram is attached below.

Using Trigonometric ratio

\tan 48^\circ = \dfrac{h}{50} \\h=50 \times \tan 48^\circ\\h=55.5$ feet (to the nearest tenth)

The height of the house is 55.5 feet to the nearest tenth.

<u>Question 2</u>

In the diagram, we are required to find the distance the bird must fly to be directly above the fish. This has been represented by x.

Using Trigonometric ratio

\tan 15^\circ = \dfrac{2}{x} \\x \tan 15^\circ=2\\x=2 \div \tan 15^\circ\\x=7.5 $ feet (to the nearest tenth)

The distance the bird must fly to be directly above the fish is 7.5 feet.

leva [86]

Answer:

Correct option is:

C. 2

Step-by-step explanation:

We have to find the exponent in the term -3x²

An exponent refers to the number of times a number is multiplied by itself.

Here, x is multiplied to itself 2 times

i.e. x\times x=x^2

Hence, exponent in the term -3x² is:

2

So, the correct option is:

C. 2

Simplify the following expression:
Salsk061 [2.6K]

Simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

The options are:

A) -x⁴ - 2x - x + 2

B) -x⁴ - 2x³ + 2x + 5

C) -2x³ + 1

D) -x - 2x² + 2x + 5

We have an expression:

= (x + 3) - [(x + 2)(x³ - 1)]

\rm =x+3-\left(x+2\right)\left(x^3-1\right)

\rm =x+3-x^4+x-2x^3+2

\rm =-x^4-2x^3+2x+3+2

\rm =-x^4-2x^3+2x+5

Thus, simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.
