Jayden has a bag that contains pineapple chews, strawberry chews, and lime chews.
He performs an experiment. Jayden randomly removes a chew from the bag, records
the result, and returns the chew to the bag. Jayden performs the experiment 41 times.
The results are shown below:
A pineapple chew was selected 31 times.
A strawberry chew was selected 4 times.
A lime chew was selected 6 times.
Based on these results, express the probability that the next chew Jayden removes
from the bag will be strawberry chew as a fraction in simplest form.

Write two ratios equal to each other :

12/5 = 8/x(second speed)

Cross multiply:

12x = 40

Divide both sides by 12:

X = 3.333 or 3 1/3 km/h

second speed = 3.33 ( as a decimal) or 3 1/3 ( as a fraction) km/h

Answer:

a) growth

b) $500

c) 6% = 0.06

d) [tex]f(x)=500(1.06)^x[/tex]

e) $595.51

Step-by-step explanation:

Part (a)

Exponential GROWTH, since interest is applied to the account each year.

Part (b)

Initial amount = $500

Part (c)

Growth factor = 6% = 0.06 (in decimal form)

Part (d)

General form of exponential growth function:

[tex]f(x)=a(1+r)^x[/tex]

where:

Given:

[tex]\implies f(x)=500(1+0.06)^x[/tex]

[tex]\implies f(x)=500(1.06)^x[/tex]

Part (e)

when x = 3

[tex]\begin{aligned}\implies f(3) & =500(1.06)^3\\ & = 595.51\: \sf(nearest\:hundredth)\end{aligned}[/tex]

Answer:

Permutation is an arrangement of things where order of arrangement matters. The position of each thing in a permutation matters. Thus, Permutation can be associated with Position.

Combination is grouping/selection of things where order does not matter. Permutation can be considered as an ordered combination.

Answer:

First number = 9

Second number = 7

Step-by-step explanation:

Let x be the first number and y be the second.

2x + y = 25

3x - y = 20

1) Add them together.

5x = 45

x = 9

2) Solve for y.

2(9) + y = 25

y=7

3) Check your work on the other equation.

3(9) - (7) = 20

27 - 7 = 20

20 = 20

Therefore the first number is 9 and the second number is 7.

===========================================================

Explanation:

The given statement is claiming something like [tex]P(X < 2)[/tex] produces a different result compared to [tex]P(X \le 2)[/tex]. The subtle difference of course is the "or equal to".

When talking about continuous random variables, the two values are the same. Why? Because probability of selecting *exactly* X = 2 is going to be zero. Think of a very very thin strip of height P(X = 2) and the width is approaching zero. The width is doing this because we're trying to pinpoint X = 2 itself. As you can see, this skinny rectangle will have its area approach 0. Ultimately, whether we compute [tex]P(X < 2)[/tex] or [tex]P(X \le 2)[/tex], it doesn't matter. They both produce the same result.

If you are a visual learner, consider the standard normal distribution. Now consider the task if shading to the left of z = 2. This area describes both probabiltiies mentioned above.

If X is a continuous random variable, then [tex]P(X < 2) = P(X \le 2)[/tex] and we can change the "2" to any number we want to have the same outcome.

Therefore, the original claim is false.

-------------------------

Extra info:

Now if X was discrete (say from the binomial distribution), then the two probabilities would be different. This is because

[tex]P(X < 2) = P(0) + P(1)\\\\P(X \le 2) = P(0) + P(1) + P(2)\\\\P(X < 2) \ne P(X \le 2) \ \text{only if X is discrete}[/tex]

We can see in this case that the second line has P(2) while the first one does not.

So the original claim would be true if we changed "continuous" to "discrete".

Answer:

4

Step-by-step explanation:

[tex](-1 (\frac{2}{3} - 4)) / (5/6)[/tex]

Let's solve for the numerator first:

PEMDAS says parenthesis first so...

2/3 - 4, we'll turn 4 into an improper fraction so it's easier

2/3 - 12/3 = -10/3

-1(-10/3) = (+)10/3

Now, we replace this as the numerator:

(10/3) / (5/6)

To divide, we multiply the first fraction by the reciprocal of the second:

(10/3) * (6/5) = 60/15

now simplify.....

60/15 = 4 or in other words, {15 * 4 = 60}

So, the answer is 4!

Answer:

y = -3x -1

Step-by-step explanation:

Hi there!

We are given a line on a coordinate grid, with 2 marked points, (-1, 2) and (1, -4)

We can use these points to help find the equation of the line, which we can write in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

First, we need to find the slope of the line
The formula for the slope calculated from 2 points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything we need to find the slope, but let's label the values of the points to help avoid confusion.

[tex]x_1=-1\\y_1=2\\x_2=1\\y_2=-4[/tex]

Now substitute these values into the formula to find the slope

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-4-2}{1--1}[/tex]

Simplify

m=[tex]\frac{-4-2}{1+1}[/tex]

m=[tex]\frac{-6}{2}[/tex]

Divide

m= -3

The slope of the line is -3

We can substitute this into the formula.
Here's our line so far:

y = -3x + b

Now we need to find b

As the equation passes through the points (-1, 2) and (1, -4), we can use either one to find the value of b

Taking (-1, 2) for example:

Substitute -1 as x and 2 as y.

2 = -3(-1) + b

multiply

2 = 3 + b

Subtract 3 from both sides

-1 = b

Substitute -1 as b.

y = -3x - 1

Hope this helps!

A geometric series is the sum of an unlimited number. The common ratio of the geometric sequence is 3.

A geometric series is the sum of an unlimited number of terms with a fixed ratio between them.

Given the value of a₁ is 10, while the value of a₅ is 810, therefore, the common ratio can be written as,

[tex]\dfrac{a_5}{a_4} \times \dfrac{a_4}{a_3} \times \dfrac{a_3}{a_2}\times \dfrac{a_2}{a_1} = r \times r \times r \times r\\\\\\\dfrac{a_5}{a_1} = r^4\\\\\\dfrac{810}{10} = r^4\\\\\sqrt[4]{81} = r\\\\r = 3[/tex]

Answer:

580.4 cm^2 to the nearest tenth.

Step-by-step explanation:

If we draw a perpendicular line from the top right vertex to the base we split the figure into 2 triangles and a rectangle in the center.

Left side triangle:

base = √(28^2 - 20^2)    (using Pythagoras theorem

= 19.600

So its area = 1/2 * 19.6 * 20 = 196 cm^2.

Right side triangle:

Base = √(30^2 - 20^2) = 22.361

Area = 1/2 * 22.361 * 20 = 223.61 cm^2

Rectangle:

Base of rectangle = 50 - 19.6 - 22.361 = 8.039.

Area = 8.039 * 20 = 160.78.

So the area of the whole figure

= 196 + 223.61 + 160.78

= 580.39 cm^2.

Step-by-step explanation:

add up all the x's and distribute them starting from the outside until you get to the middle. if there is an odd number of x's (which there isn't), the last x to be placed will be on the spot that is the median. If there is an even number of x's, and they both land on the same spot, that spot will be the median, and if they are next to each other, the median will be between them.

The size of the sample space would be  { H-1 H-2 H-3 H-5 H-6 T-1 T-3 T-4 T-5 }.

Sample space is the set of all possible outcome the considered random experiment can result to.

Thus, suppose we toss a coin, then tossing a coin is a random experiment, and the sample space is {'head', 'tail'}.

We ignore other outcomes like slant coin, or standing coin by assuming that coin is very thin to stand and always falls down.

Ella rolls a die and then flips a coin. The sample space for this compound event is represented in the table (H is heads and T is tails).

Answer:

$15.00

Step-by-step explanation:

Just did the quiz

By evaluating the piecewise function, we will see that the brother owes $15.

The piecewise function is:

y = 26,   if 0 < h < 4

y = 26 + 5*(h - 4),  if 4 < h < 8

y = 60, if 8 < h

Barbara uses it for 3 hours, so we only need to use the first part for her, so she needs to pay $26.

Then the brother uses it for 4 hours (and we need to add the 3 hours that Barbara used it, so we have h = 7).

Then for the 7 hours the two brothers need to pay:

y = $26 + $5*(7 - 4) = $41

If we subtract the part that Barbara needs to pay we get.

$41 - $26 = $15

This means that the correct option is $15.
