Answer: 0.046

Step-by-step explanation:

From the question,

orange jelly beans= 7

Cherry jelly beans =9

Lemon jelly beans = 3

Licorice jelly beans = 15

Blueberry jelly beans = 6

Total jelly beans = 40

The probability of choosing the first cherry jelly beans will be = 9/40

After the first one is chosen, there'll be 8 cherry jelly beans and total of 39 left. The probability of choosing the second one will be = 8/39

The probability of choosing two cherry jelly beans in a row will be:

= 9/40 × 8/39

= 72/1560

= 0.046

f the line passing through the points (1, a) and (5, −2) is parallel to the line passing through the points (2, 8) and (−5, a +
aleksandrvk [35]

Answer:

a=-6

Step-by-step explanation:

Line 1:  (1, a) and (5, −2)

slope of the   line is

slope = \frac{y_2-y_1}{x_2-x_1} =\frac{-2-a}{5-1} =\frac{-2-a}{4}

Line 2:  (2, 8) and (−5, a + 7)

slope of the   line is

slope = \frac{y_2-y_1}{x_2-x_1} =\frac{a+7-8}{-5-2} =\frac{a-1}{-7}

when the lines are parallel then slopes are equal

\frac{a-1}{-7} =\frac{-2-a}{4}

cross multiply it

4(a-1)=-7(-2-a)

4a-4=14+7a

subtract 4a from both sides

-4=14+3a

-18=+3a

divide both sides by 3

a=-6

The area of the shape is 260 square cm

<h3>How to determine the area of the shape?</h3>

The given parameters are:

<u>Triangle</u>

Height = 6cm

Base = 20 cm

<u>Rectangle</u>

Length = 10cm

Width = 20 cm

The area of the shape is calculated as:

Area = 0.5 * Base * Height + Length * Width

So, we have:

Area = 0.5 * 20 * 6 + 10 * 20

Evaluate

Area = 260

Hence, the area of the shape is 260 square cm
