Answer:

Eleana is 20 years old and her grandfather is 80 years old.

Step-by-step explanation:

So first off, we want to make variables to represent Eleana and her grandfather.

Let x represent Eleana's age.

Since her grandfather is four times older than Eleana,

The expression should be 4x+x=100

Step One

Add the x's together and you get 5x=100.

Step Two

Divide both numbers by 5 to solve for x.

x=20

Step-by-step explanation:

The system of equations that matches the graph is

x + y = 2
3x - y = 1

What is the system of equations

From the question, we are to write a system of equations for the two straight lines shown

To do this, we will pick two points on each line

Red line:

(0, 2) and (2, 0)

Using the formula,

y - y1 / x - x1 = y2 - y1 / x2 - x1

(y - 2) / (x - 0) = (0 - 2) / (2 - 0)

Simplifying

(y - 2) / x = -2 / 2

(y - 2) / x = -1

y - 2 = -x

Thus,

x + y = 2

Blue line:

(1, 1) and (0, -2)

Using the formula,

y - y1 / x - x1 = y2 - y1 / x2 - x1

(y - 1) / (x - 1) = (-2 - 1) / (0 - 1)

Simplifying

(y - 2) / (x - 1) = -3/ -1

(y - 2) / (x - 1) = 3

y - 2 = 3(x - 1)

y - 2 = 3x - 3

Thus,

3x - y = -2 + 3

3x - y = 1

Hence,

The system of equations is

x + y = 2
3x - y = 1

Answer:

false

Step-by-step explanation:

it fails the vertical line test, (x cannot be equal to 2 or more y values or its not a function)

To check if a graph is a function, we use the vertical line test. If your run a vertical line over the function, are there any places where the line intersects the graph more than once? If so, it's not a function.

In this case, if we have a line at x = 0, the line will go through more than one point - (0, 0) and (0, 3.1) [exact value doesn't matter, what matters is that there's a point there]. That means that this is not a function, so the statement is false.

Answer:

The value of a = 4 and b = 3 make the equation true, the correct option is D.

Step-by-step explanation:

Step-by-step explanation:

Width of the envelope = 3 inches

Diagonal of the envelope = 7 inches

To find:

The length of the envelope.

Let the length of the envelope be 'l'

We can use pythogoras theorem to calculate the length.

l = √(49-9)

l = √(40)

l = 6.3 inches

The length of the envelope is 6.3 inches

Answer:

C because the rest are pythagoreaum theroems 1 squared plus 2 squared does not equal 3 squared.

hello :

the vertex is (-1 ;0)

the axis of symmetry  is : x= -1

The expression '4 - 2 = 2' can be rewritten as '4 + (-2) = 2' or 'subtracting 2 from 4 equals 2'. However, '4 + 2 = 6' is not equivalent to the initial expression and represents an addition, not a subtraction.

The expression '4 - 2 = 2' can be rewritten in a number of ways. Firstly, we can consider '4 - 2' as '4 + (-2)', which indeed equals 2. Moreover, another way to rephrase '4-2' is 'subtracting 2 from 4', still equals 2. A different expression, '4 + 2', however, results in a value of 6, which is not equivalent to our initial expression '4 - 2 = 2'.

We use the concepts of addition and subtraction to rewrite these expressions. It is crucial to understand that the operation of subtraction can be imagined as the addition of a negative number to a positive one. Whereas, the operation 4 + 2 = 6 belongs to a different category, as it is straightforward addition, not a subtraction.

Final answer:

The probability that both animal crackers Junior grabs from the box are lions is approximately 5.75%.

Explanation:

The question asks to calculate the probability that both animal crackers Junior grabs from the box are lions. With a total of 40 animal crackers (10 elephants, 10 monkeys, 10 zebras, and 10 lions), the probability of picking a lion first is 10/40 or 1/4. After eating one lion, there are now 39 crackers left and only 9 lions. The probability of picking a second lion is 9/39. To find the probability that both crackers eaten are lions, we multiply the probabilities of these two independent events: (1/4) * (9/39) = 9/156 or 1/17.39. This simplifies to approximately 0.0575 or 5.75%.

Answer:

12762.72 cubic meters

Step-by-step explanation:

The volume of a cylinder is denoted by the formula: [tex]V=\pi r^{2} h[/tex], where r is the radius and h is the height.

Here, we see that the height h = 11.5 m. We also see that the diameter is 37.6 meters. Since diameter = 2 * radius, we can divide this number by 2 to get the radius: r = 37.6/2 = 18.8 meters.

Now substitute these values into the equation:

[tex]V=\pi *(18.8^2)*11.5=3.14*(18.8^2)*11.5=12762.72[/tex] cubic meters

Hope this helps!

Answer:

[tex]12769.19m^{3}[/tex]

Step-by-step explanation:

The formula for the area of a circle is:

[tex]\pi r^{2}[/tex]

To work this out you would first have to find the area of the circle. To do this you would first divide 37.6 by 2, which gives you 18.8. Then to find the area you would multiply pi by 18.8 squared, which gives you [tex]1110.36m^{2}[/tex]. Then To find the volume you would multiply 1110.36 by 11.5, which gives you [tex]12769.19m^{3}[/tex].

To find the volume of a prism you would find the area of the main face and multiply it by the height.

1) Divide 37.6 by 2.

[tex]37.6/2=18.8[/tex]

2) Multiply [tex]\pi[/tex] by 18.8 squared.

[tex]\pi *18.8^{2}=1110.36m^{2}[/tex]

3) Multiply 1110.34 by 11.5.

[tex]1110.36*11.5=12769.19m^{3}[/tex]

Remember when finding the area, thee answer is always going to be squared.

Remember when finding the volume the answer is always going to be cubed.

Answer:

a) both have the same spread

Step-by-step explanation:

Mean of Brand A > Mean of Brand B

Median of A > Median of B

Spread of:

A: 22 - 18 = 4

B: 18 - 14 = 4

The spread of the data which is obtained by calculating the Interquartile range of each distribution since the distributions are skewed is 2 for brand A and brand B. Hence, the spread is the same.

The distribution of BRAND A chips :

18, 19, 19, 19, 19, 19, 19, 20,20,20,20,20,20,21,21,21,21,21,21,22

The Upper quartile, Q3 ;

Q3 = 0.75 × (n + 1)th term

Q3 = 0.75 × 21 = 15.75 th term = 21

The Lower quartile, Q1 ;

Q1 = 0.25 × (n + 1)th term

Q1 = 0.25 × 21 = 5.25 th term = 19

The IQR = Q3 - Q1 = (21 - 19) = 2

The distribution of BRAND B chips :

14,14,14,14,14,14,14,14,15,15,15,15,15,15,16,16,16,16,16,18

The Upper quartile, Q3 ;

Q3 = 0.75 × (n + 1)th term

Q3 = 0.75 × 21 = 15.75 th term = 16

The Lower quartile, Q1 ;

Q1 = 0.25 × (n + 1)th term

Q1 = 0.25 × 21 = 5.25 th term = 14

The IQR = Q3 - Q1 = (16 - 14) = 2

Therefore, the spread of distribution of BRAND A and B are the same.
