then, the number of non-coco ones is lowered by 1 and the number of total too, so

17/19 for the second chocolate not to be coco cream

The chance that neither of the 2 chocolates is coconut cream is 18/20*17/19 ≈ 0.805263158

The value of the given expression is  -121/ 30.

PEMDAS stands for parentheses, exponents, multiplication, division, addition, then subtraction. It is basically the rule of the order in which a mathematical expression must be solved.

Here, we are given an expression- -2/3 (1.5 ÷ 0.25 ÷ 5/4) -5/6

It can be written as -2/3 (15/10 ÷ 25/ 100 ÷ 5/4) -5/6

= -2/3 (3/2 ÷  1/4 ÷ 5/4) -5/6

As per the rules of PEMDAS, we first deal with the terms inside the bracket-

(3/2 ÷  1/4 ÷ 5/4) = (3/2 × 4 × 4/5)

= (3 × 2 × 4/5)

= 24/5

Thus, the expression becomes-

-2/3 (24/5) -5/6

= -48/ 15 - 5/6

LCM of 15 and 6 is 60

⇒ -(48 × 4)/ 60 - (5 × 10)/ 60

-192/ 60 - 50/ 60

= (-192 - 50)/ 60

= -242/ 60

= -121/ 30

Thus, the value of the given expression is  -121/ 30.

Answer:

x = 0 or x = 1/4

Step-by-step explanation:

f(x) = 4x^2-x-3 = -3

4x^2 - x - 3 = -3

4x^2 - x = 0

x(4x - 1) = 0

x = 0 or 4x - 1 = 0

x = 0 or x = 1/4

Answer:

The values for x are x =0  x = 1/4

Step-by-step explanation:

f(x)=4x^2-x-3

find f(x) = -3

Let f(x) = -3

Solve for x

-3 = 4x^2-x-3

Add 3 to each side

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

0  = 4x^2-x

Factor out an x

0 = x( 4x-1)

Using the zero product property

0 = x    4x-1 =0

0=x     4x=1

0=x   x = 1/4

The values for x are x =0  x = 1/4

That is not the easiest graph I've seen to interpret. What it shows is that each cup of juice is 3/4 of a cup.

The graph says she has 4 cups that she can give out. She has 1/4 cup left over which is why it is marked.

Technically the answer is 4 cups with 1/4 cup left over, so the answer should be A.

The percentage of 0 - 17 in 2015 is 23.97% and the percentage is decreasing by 0.048% in 2015

The equation of the function is given as

P(x) = 26x^-0.03

In 2015, x = 15

Substitute x = 15 in the equation P(x) = 26x^-0.03

P(15) = 26 * 15^-0.03

Evaluate the expression

P(15) = 23.97

Hence, the percentage of 0 - 17 in 2015 is 23.97%

The equation of the function is given as

P(x) = 26x^-0.03

Differentiate the function

P'(x) = -0.03 * 26x^-1.03

In 2015, x = 15

Substitute x = 15 in the equation

P'(15) = -0.03 * 26 * 15^-1.03

Evaluate

P'(15) = -0.048

Hence, the percentage is decreasing by 0.048% in 2015

Interval Notation

Interval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers. For example, the set of numbers x satisfying 0 ≤ x ≤ 5 is an interval that contains 0, 5, and all numbers between 0 and 5.

Different Types Of Intervals

Intervals can be classified based on the numbers the set comprises. Some sets include the endpoints specified in the notation, while some might partially or not include the endpoints. In general, there are three types of intervals given as,

Open Interval

Closed Interval

Half-Open Interval

Let us understand the interval notation and different types of intervals in detail using solved examples.

Interval Notation:

y = |x4|

(−∞,∞)

Set-Builder Notation:

{x|x∈R}

The range is the set of all valid

Answer:

C. Left 7

Step-by-step explanation:

The question asks us about the number of units the x-coordinates of the parallelogram moved, therefore we have to look for the horizontal translation of the points A, B, C, and D.

To do this, we can look at the position of any of these points and the position of its corresponding point, to figure out how many units to the left or right they have moved.

For example, let's look at A and A':

To go from A to A', we have to move 7 units to the left.

It's the same for B and B' as well as the other points and their corresponding points.

Therefore the x-coordinates of parallelogram ABCD have moved 7 units to the left.

Answer:  y = –13.5x + 60

Step-by-step explanation:

The volume is 3105 and the surface area is 1742

The given parameters are

Length = 27 yards

Width = 23 yards

Height = 5 yards

The volume is

Volume = Length * width * height

So, we have

Volume = 27 * 23 * 5

Evaluate

Volume = 3105

The surface area is

A =2 *(LW + LH + WHW)

So, we have

A = 2 * (27 * 23 + 27 * 5 + 23 * 5)

Evaluate

A = 1742

Hence, the volume is 3105 and the surface area is 1742

Answer:

The first graph.

Hope this helps :)

Step-by-step explanation:

The y-intercept in the equation y = x^2 - 1 is -1.

So the first graph represents the point where the line intercepts the y-axis which is at - 1.

The y-intercept for the second graph is not - 1.

So the first graph would be correct for the equation

So the first graph would be correct for the equation y = x^2 - 1

The dot plot that has a symmetric distribution is option b.

A dot plot is a graph that has similarities with a histogram. A dot plot is made up of a number line and dots. A dot plot is used to represent the frequency of a data set.

The dots in the dot plot represent the frequency of the data. The greater the frequency of a data, the greater the number of dots the number has. For example, if a number has a frequency of 6, it would have 6 dots have it.

A dot plot is symmetric if the left side of the graph and the right side of the graph are mirror images of each other. A dot plot is skewed to the left if there are more dots on the left side of the graph. A dot plot is skewed to the right if there are more dots on the right side of the graph.

The inequality between (5/6), (1/2), (3/9) and 1 can be best described by

[tex][\frac{3}{9} < \frac{1}{2} < \frac{5}{6} < 1][/tex].

As per the question statement, we are provided with three proper fractions, (5/6), (1/2), (3/9) and an integer, 1.

We are required to correctly compare the inequality between the question mentioned terms.

Since all three fractions are proper fractions, i.e., their numerators are less than their denominators, hence, all three fractions are less than the integer 1.

Thus, we are required to determine the order of magnitude between the fractions. To do so, we will calculate the L.C.M of the denominators.

L.C.M of 2, 6 and 9 is 18.

Therefore, we will multiply both the numerator and denominators of (5/6) with 3, and we will obtain [tex]\frac{5*3}{6*3} =\frac{15}{18}[/tex].

Similarly, we will multiply both the numerator and denominators of (1/2) with 9, and we will obtain [tex]\frac{1*9}{2*} =\frac{9}{18}[/tex].

Finally, we will multiply both the numerator and denominators of (3/9) with 2, and we will obtain [tex]\frac{3*2}{9*2} =\frac{6}{18}[/tex].

Now comparing [tex][\frac{15}{18}, \frac{9}{18}, \frac{6}{18}],[/tex] we can see than all the denominators are now same (18). Hence, the order of magnitude of the fractions can be determined in the order of magnitude of the numerator values, i.e.,

[15 > 9 > 6] or, [6 < 9 < 15].

Therefore, [tex][\frac{6}{18} < \frac{9}{18} < \frac{15}{18}][/tex], or, [tex][\frac{3}{9} < \frac{1}{2} < \frac{5}{6}][/tex].

And since 1 is greater than any proper fraction, The inequality between (5/6), (1/2), (3/9) and 1 can be best described by [tex][\frac{3}{9} < \frac{1}{2} < \frac{5}{6} < 1][/tex].
