Determine the sample space of all of the possible outcomes one of choosing a card numbered 1, 2, 3, or 4, and a blue, green, or a yellow marble. How many outcomes involve a blue marble
Answers
Answer:
[tex]Sample\ Space = \{1\ Blue, 1\ Green, 1\ Yellow, 2\ Blue, 2\ Green,[/tex] [tex]2\ Yellow, 3\ Blue, 3\ Green, 3\ Yellow, 4\ Blue, 4\ Green, 4\ Yellow\}[/tex]
The number of occurrence that involve blue is 4
Step-by-step explanation:
Given
[tex]Card\ Number = \{1,2,3,4\}[/tex]
[tex]Marble = \{Blue, Green, Yellow\}[/tex]
Required
Determine the sample space
To determine the sample space, we have to select a card number and write it alongside the marble colours.
i.e.
[tex]Sample\ Space = \{1\ Blue, 1\ Green, 1\ Yellow, 2\ Blue, 2\ Green,[/tex] [tex]2\ Yellow, 3\ Blue, 3\ Green, 3\ Yellow, 4\ Blue, 4\ Green, 4\ Yellow\}[/tex]
Solving (b): Outcomes that involves blue marble
First, we list them out
[tex]Blue = \{1\ Blue, 2\ Blue, 3\ Blue, 4\ Blue}[/tex]
Number of occurrence is 4
Maddox McDonald A caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes. How fast does the caterpillar move in feet per minute? 1 3
Answers
Answer: 2/3 feet per minute
Step-by-step explanation:
From the question, we are informed that a caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes.
The rate at which the caterpillar move in feet per minute will be:
= 4 2/3 ÷ 7
= 14/3 ÷ 7
= 14/3 × 1/7
= 14/21
= 2/3 feet per minute

How do you write 58.84% as a decimal?
Answers
Answer:When you ask, "What is 58.84 as a decimal?", we assume you want to know what 58.84 percent is as a decimal. In other words, 58.84 percent converted to decimal.
First, we will tell you why it is useful to know 58.84 as a decimal.
Normally, to calculate 58.84 percent, you would multiply a number by 58.84 percent and then you would take the product of that and divide it by 100 to get the answer.
Instead, you can simply multiply a number by 58.84 as a decimal to get the answer.
58.84 ÷ 100 = 0.5884

Answer:
x = 10; y = 10
Step-by-step explanation:
[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]
[tex] \cos( {theta} ) = \frac{adjacent}{hypotenuse} [/tex]
[tex] \tan( {theta} ) = \frac{opposite}{adjacent} [/tex]
theta = 45°
opposite = x
hypotenuse = 10√2
adjacent = y
1) find x using sin formula[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]
[tex] \sin(45) = \frac{x}{10 \sqrt{2} } [/tex]
[tex] \sin(45) \times 10 \sqrt{2} = x[/tex]
[tex]10 = x[/tex]
[tex]x = 10[/tex]
2) find y using cos formula[tex] \cos( {theta} ) = \frac{adjacent}{hypotenuse} [/tex]
[tex] \cos(45) = \frac{y}{10 \sqrt{2} } [/tex]
[tex] \cos(45) \times 10 \sqrt{2} = y[/tex]
[tex]10 = y[/tex]
[tex]y = 10[/tex]

Just divide 1,300 by 5.
260 would be your answer. If you want an explanation, if you think about the term 100%, that's the total at the time. Amplifying that 100% by five would practically mean five times the amount of 100%, so 500%. You're just multiplying the amount of bunnies at the time by 5. (500% in decimal form is 5)

BRAINLIEST. Ariana has a loyalty card good for a discount at her local hardware store. The item she wants to buy is priced at $9, before discount and tax. After the discount, and before tax, the price is $7.56. Find the percent discount.
Answers
Answer:
16%
Step-by-step explanation:
Given data
Initial cost= $9
final cost= $7.56
Required
The percent discount
Step two
Percent discount= final-initial/initial *100
Percent discount= 9-7.56/9 *100
Percent discount=1.44/9 *100
Percent discount=0.16 *100
Percent discount=16%
Hence the percent discount is 16%
