Answer:

Step-by-step explanation:

the balloon starts at (10, 0 )

it ends at 16,0)

in the middle it's at between 10 and 16 , so say about 13, where it reaches 27

so in the middle it's (13,27)

so ( 11, 9)

(12, 18)

got 13

(14, 18)

(15, 9)

got 16

What are the steps on how do you divide fractions using area models?

topjm [15]

Use keep, change, flip!
Ex: 1 / 3
— —
2 4

Keep the 1/2
Change the division sign to a multiplication sign
Flip the 3/4 to be 4/3

1 X 4
— —
2 3

Then, multiple and simplify as usual!

1 X 4= 4
2 X 3= 6

4 = 2
— —
6 3

The answer would be 2
—
3

Hope this helps, brainliest please! :)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

<u>Algebra I</u>

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find points from graph.</em>

Point (2, 3)

Point (3, 0)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>.

Substitute [SF]: $m=\frac{0-3}{3-2}$
Subtract: $m=\frac{-3}{1}$
Divide: $m=-3$

Question 1 on my integrated geometry test

NemiM [27]

Answer:

B. 15 cm

Step-by-step explanation:

Hypotenuse (h) = 17 cm

perpendicular (p) = 8 cm

base (b) = YZ = ?

We know that by using Pythagoras theorem

b = √ (h² - p²)

= √ ( 17² - 8²)

= √225

= 15 cm

YZ = 15 cm

Hope it will help :)❤

Suppose that 30% of the applicants for a certain industrial job possess advanced training in computer programming. Applicants ar

Charra [1.4K]

Answer:

Step-by-step explanation:

From the given information:

Assume X represents the no. interviewed until 1 has advanced training.

X obeys a Geometric distribution with parameter 0.3.

X $\sim$ Geom (0.30)

For geometric distribution, the probability density is:

$P(X =x) = p(1-p) ^{x-1} \ \ \ where; x =1,2,3...$

TO calculate the required probability;

$P(X =5) =0.30 (1-0.30)^{5-1}$

$P(X =5) =0.30 (0.70)^{4}$

$P(X=5) = 0.30 \times 0.2401$

$\mathbf{P(X=5) = 0.07203}$

(b)

The expected no. of applicants that need to be interviewed are:

$E(X)=\dfrac{1}{p}$

$E(X)=\dfrac{1}{0.30}$

E(X) = 3.33

(c)

The mean and the variance can be computed as:

$E(Y) = \dfrac{1}{p}$

$E(Y) = \dfrac{1}{0.30}$

E(Y) = 3.33

$V(Y)=\dfrac{1-p}{p^2}$

$V(Y)=\dfrac{1-0.3}{0.3^2}$

$V(Y)=\dfrac{0.7}{0.3^2}$

$V(Y)=7.778$

Suppose C represents the no. of the total cost and given that each interview costs $30.

Then C = 30Y

Recall that; C is constant for a random variable X

∴

E(C) = E(30Y)

E(C) = 30E(Y)

E(C) = 30*3.33

E(C) =99.9

E(C) $\simeq$ 100

V(C) = V(30Y)

V(C) = 900 V(Y)

V(C) = 900*7.778

V(C) = 7000.2

V(C) $\simeq$ 7000
