Answer:
B
Step-by-step explanation:
Even numbers = 2,4,6
Odd numbers = 1,3,5
Same amount of numbers
Answer:
B. The events are equally likely.
Step-by-step explanation:
On a 6-sided number cube, there are 3 even numbers (2, 4, 6) and 3 odd numbers (1, 3, 5). There is a 1/2 (3 of 6) chance you will roll an even number, and a 1/2 chance you will roll an odd number. These chances are the same, so B is the answer.
y is such that 4y - 7 ≤ 3y and 3y ≤ 5y + 8.
A. What range of values of y satisfies both inequalities?
B. Hence express 4y - 7 ≤ 3y ≤ 5y + 8 in the form a ≤ y ≤ b, where a and b are both integers.
( I will give brainliest to whoever answers correctly)
Answer:
-4 ≤ y ≤ 7
Step-by-step explanation:
Inequalities
Solve the system of inequalities:
4y - 7 ≤ 3y [1]
3y ≤ 5y + 8 [2]
A.
Subtracting 3y to [1]:
y - 7 ≤ 0
Adding 7:
y ≤ 7
Subtracting 5y to [2]:
-2y ≤ 8
Dividing by -2 (and flipping the sign):
y ≥ -4
The solution of the system is all the values of y greater or equal to -4 and less or equal to 7.
B.
The solution can be expressed as:
-4 ≤ y ≤ 7
11 - 2x = 45
what are the steps to this
Answer:
x = -17
Step-by-step explanation:
11 - 2x = 45
We first want to subtract 11 from both sides, so that we have the variable and it's factor on its own side. Making the equation:
-2x = 34
Next, we are going to divide each side by the variables' factor, which in this case is -2. However, there is a slightly longer way to do this, but when you're doing it by hand, it is much easier. I will be showing that way below.
So, instead of dividing either side by -2, we are going to divide both sides by 2. Giving us:
-x = 17
This next step is easy peasy. Since the negative is on the variables side and we need the variable to be positive, we just switch the position of the negative to the numerical side. Shown below.
-x = 17
to
x = -17
So, our final answer is x = -17
Hope this helps!
Answer:
Step-by-step explanation:
Solution
11 - 2x = 45
or, 2x=11-45
or, 2x=-34
x=-17

You are using a magnifying glass that shows the image of an object that is six times the object's actual size. Determine the length of the image of the termite seen through the magnifying glass.
Answer:
3 inches
Step-by-step explanation:
Typical length of a termite is 1/2 inch
[tex]Lenght \ seen \ through\ magnifying\ glass=\frac{1}{2}(6) =3[/tex]
The length of the image of the termite seen through the magnifying glass is 3 inches.
What is magnifying glass?A convex lens is used in a magnifying glass to provide an enlarged image of an object. Typically, the lens is fixed inside of a frame with a grip. You can use a magnifying glass to focus light, for example, to concentrate the sun's radiation and create a hot spot at the centre to start a fire.
Given that you are using a magnifying glass that shows the image of an object that is six times the object's actual size.
The length of the image of the termite seen through the magnifying glass will be calculated as,
Length = (1 / 2 ) x 6
Length = 3 inches
Therefore, the length of the image of the termite seen through the magnifying glass is 3 inches.

Solve for x in simplest form.
2= 1/2 (5x-8)
Answer:
x = [tex]\frac{12}{5}[/tex]
Step-by-step explanation:
Given
2 = [tex]\frac{1}{2}[/tex] (5x - 8) ( multiply both sides by 2 to clear the fraction )
4 = 5x - 8 ( add 8 to both sides )
12 = 5x ( divide both sides by 5 )
[tex]\frac{12}{5}[/tex] = x
Isabelle has $5.45 in her purse. If she has five more nickels than dimes, and twice as many quarters than dimes, how many of each type of coin does she have?
Answer:
Nickel = 13
Dimes = 8
Quarters = 16
Step-by-step explanation:
Let N denote Nickel,
Let D denote dime
Let Q denote quarter
Now, from online conversions;
1 nickel = 5 cents
Also, 1 dime = 10 cents
Also, 1 quarter = 25 cents
Isabelle has $5.45 which is also 545 cents.
Thus, we have;
5N + 10D + 25Q = 545 - - - (eq 1)
We are told that;
she has five more nickels than dimes, and twice as many quarters than dimes.
Thus;
N = D + 5
Also, Q = 2D
Plugging them for N and Q in eq 1 givens;
5(D +5) + 10D + 25(2D) = 545
5D + 25 + 10D + 50D = 545
25 + 65D = 545
65D = 545 - 25
65D = 520
D = 520/65
D = 8
Thus; N = D + 5 = 8 + 5 = 13
Q = 2D = 2 × 8 = 16

The second column is labeled likes with entries a, c, 19. The third column is labeled dislikes with entries 15, 16, e. The fourth column is labeled total with entries b, d, 50.
A group of 50 people were asked their gender and if they liked cats. The data from the survey are shown in the Venn diagram.
Determine the value for each variable in the two-way table.
a =
b =
c =
d =
e =
Please give me the right answer!
Answer:
E = 15 +16 = 31
6 males like cats ( the middle section) so C = 6
d = 6 +16 = 22
a = 19-6 = 13
b = 50-22 = 28
so in order: a = 13, b = 28, c = 6, d = 22, e = 31
Step-by-step explanation:
The required value for each variable in the two-way table is given as, a = 13, b = 28, c = 6, d = 22, and e = 31.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
From the table,
e = 15 + 16 = 31
At the middle of the table, c = 6 {6 males like cats}
d = 6 + 16 = 22
a = 19 - 6 = 13
b = 50 - 22 = 28
Thus, the required value for each variable in the two-way table is given as, a = 13, b = 28, c = 6, d = 22, and e = 31.

Round 503.782 to the nearest tenth.
Answer:
503.8
Step-by-step explanation:
Since the hundredths place is above 4, you round up.
Answer:
503.8
Step-by-step explanation:
Note the tenth place value.
5 (hundreds place value)
0 (tens place value)
3 (ones place value)
.
7 (tenths place value)
8 (hundredths place value)
2 (thousandths place value)
You are trying to solve for the tenths place value. In this case, locate the tenths place value. The value is a 7. Now look at the place value directly next to it (hundredths place value). It is a 8. Because 8 is greater than 4, round up.
503.782 rounded to the nearest tenths is 503.8
Note:
Note the rules of rounding. IF:
The number is 4 or less, round down.
The number is 5 or greater, round up.

Answer:
The measure of angle x° = 34°.
Step-by-step explanation:
It is given that a
We know that side of the triangle below has been extended to form an exterior angle of 146°.
It is clear that x° and 146° are adjacent angles.It is clear that x° and 146° lie on a straight line.We know that a straight line makes a straight angle of 180°.
Thus,
The sum of x° and 146° must be 180°.
x° + 146° = 180°
subtract 146° from both sides
x° + 146° - 146° = 180° - 146°
x° = 34°
Therefore, the measure of angle x° = 34°.

1) 3r² – 2r=-9
Quadratic formula
Answer:
Solving the equation [tex]3r^2-2r=-9[/tex] using quadratic formula we get: [tex]\mathbf{ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}}[/tex]
Step-by-step explanation:
We need to solve the equation [tex]3r^2-2r=-9[/tex] using quadratic formula.
The quadratic formula is: [tex]r=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
For the given equation: [tex]3r^2-2r=-9[/tex]
We can write it as: [tex]3r^2-2r+9=0[/tex]
We have a = 3, b= -2 and c=9
Putting values in quadratic formula and finding value of r
[tex]r=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\r=\frac{-(-2)\pm\sqrt{(-2)^2-4(3)(9)}}{2(3)}\\r=\frac{2\pm\sqrt{4-108}}{6}\\r=\frac{2\pm\sqrt{-104}}{6}\\We\:know\:that: \sqrt{-1}=i\\ r=\frac{2\pm\sqrt{26} \:i}{6}\\ r=\frac{2+2\sqrt{26}\:i}{6}\:or\: r=\frac{2-2\sqrt{26}\:i}{6}\\ r=\frac{2(1+\sqrt{26}\:i)}{6}\:or\: r=\frac{2(1-\sqrt{26}\:i)}{6}\\ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}[/tex]
So, solving the equation [tex]3r^2-2r=-9[/tex] using quadratic formula we get: [tex]\mathbf{ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}}[/tex]
