Using a system of equations, the number of different rolls of yarn that Laura bought is as follows:

A system of equations refers to simultaneous equations.

Simultaneous equations are two or more equations solved concurrently.

The total number of rolls of yarn bought = 25 rolls

The unit cost of multi-colored yarns = $4

The unit cost of solid-colored yarns = $3

The total cost paid for the 25 rolls of yarn = $88

Let the number of rolls of multi-colored yarns = x

Let the number of rolls of solid-colored yarns = y

Equation 1: x + y = 25

Equation 2: 4x + 3x = 88

Multiply Equation 1 by 3:

3x + 3y = 75 ... Equation 3

Subtract Equation 3 from Equation 2:

4x + 3x = 88

-

3x + 3y = 75

x = 13

Substitute x = 13 in either equations 1 or 2:

x + y = 25

The appropriate intervals to use when creating a histogram of the data are:

0 – 14, 15 – 29, 30 – 44, 45 – 59, 60 – 74.

Given information:

The following is a list of movie tickets sold each day for 10 days.

7, 18, 23, 41, 34, 12, 48, 65, 57, 52.

When creating a histogram, you want to group the data into intervals or bins.

The intervals should be chosen so that they are of equal size, and they should also include all the data values.

In this case, the data values range from 7 to 65, so we need to choose intervals that cover this range.

The appropriate intervals to use when creating a histogram of the data are:

0 – 14, 15 – 29, 30 – 44, 45 – 59, 60 – 74

These intervals capture the range of values in the data set and have equal widths, making it easy to create a histogram.

Answer:  The sum of the integers is equal to $\frac{14}{3}$ times the largest of the seven integers. What is the smallest integer that pearl wrote down?.

Step-by-step explanation:

The range of the cosine function is [-1, 1], there are no real solutions for θ in the given range.

We have,

We can solve the given quadratic equation for cos(θ) using the quadratic formula:

cos(θ) = (-b ± sqrt(b^2 - 4ac)) / 2a

Here, a = 1, b = 7, and c = 4.

Substituting these values, we get:

cos(θ) = (-7 ± √(7² - 4(1)(4))) / 2(1)

cos(θ) = (-7 ± √(41)) / 2

Since 0 ≤ θ < 2π, we need to consider only the solutions that lie in this range.

Using a calculator, we get:

cos(θ) ≈ -3.03 or -0.65

Since the range of the cosine function is [-1, 1], there are no real solutions for θ in the given range.

The exponential function that passes through the points (0,19) and (2,1539) is y = 19(9)ˣ.

We can use the two given points to form a system of two equations in two unknowns (a and b) to find the exponential function in the form y = abˣ that passes through those points.

Using the point (0,19), we get

19 = ab⁰

19 = a

Using the point (2,1539), we get

1539 = ab²

Substituting a = 19 from the first equation, we get

1539 = 19b²

Solving for b, we get

b² = 81

b = 9 or b = -9

Since we are dealing with an exponential function that models a growth, we will choose the positive value for b. Thus, b = 9.

Now that we know a and b, we can write the exponential function in the form y = abˣ

y = 19(9)ˣ

Therefore, the exponential function is y = 19(9)ˣ

Answer: The cost of a single ticket is £6.30.

Step-by-step explanation: The group bought 4 tickets and got one for free, which means they paid for 3 tickets. If each of them paid £6.30, then the total amount paid is 4 x £6.30 = £25.20.

To find the cost of a single ticket, we can divide the total paid by the number of tickets bought, which is 4:

£25.20 ÷ 4 = £6.30

Therefore, the cost of a single ticket is £6.30.

Answer:

[tex](x-7)^2+(y+2)^2=49[/tex]

Step-by-step explanation:

A tangent of a circle is a straight line that touches the circle at only one point.

Since the circle is tangent to the horizontal line y = 5, the distance between the center of the circle and the line y = 5 is equal to the radius of the circle.

Given the center of the circle is C(7, -2), the y-coordinate of the center is y = -2. Therefore, the radius of the circle is the difference between y = 5 and y = -2:

[tex]\implies r=5-(-2)=7[/tex]

The equation of a circle is:

[tex]\boxed{(x-h)^2+(y-k)^2=r^2}[/tex]

where (h, k) is the center and r is the radius.

Substitute the given center (7, -2) and found radius, r = 7, into the equation of circle:

[tex](x-7)^2+(y-(-2))^2=7^2[/tex]

Simplify:

[tex](x-7)^2+(y+2)^2=49[/tex]

Therefore, the equation of the circle that has center C(7, -2) and is tangent to the line y = 5 is:

[tex]\boxed{(x-7)^2+(y+2)^2=49}[/tex]

The expected value of a $2 ticket is $0.63

To calculate the expected value of a $2 ticket, we need to multiply the probability of winning by the value of the prize, then sum those products:

The Probability of winning the grand prize = 1/2000

Product: (1/2000) x $500 = $0.25

The Probability of winning a secondary prize: 3/2000

Product: (3/2000) x $200 = $0.30

The Probability of winning a third level prize: 8/2000

Product: (8/2000) x $20 = $0.08

The sum of the products:

$0.25 + $0.30 + $0.08 = $0.63

So the expected value of a $2 ticket is $0.63, meaning that on average, a person can expect to win $0.63 for every $2 they spend on a ticket.

The charity is expected to make a profit, which is why the answer is negative.

That is -$2 + $0.63 = -$1.37

So the expected profit for the charity per ticket sold is -$1.37, which is approximately the same as the given answer of negative $1.358(rounding off)

Angle B, in the triangle ABC is solved to be 116 degrees

Angle B is solved using the concept of triangles and exterior angle relationship. This helps to know that addition of exterior angle to ∠B to angle B results to 180 degrees. Hence we have that:

exterior angle to ∠B + ∠B = 180

given data:

∠B = (15x − 19)°

exterior angle to ∠B is (9x − 17)°

plugging in gives

9x − 17 + 15x − 19 = 180

9x + 15x = 180 + 19 + 17

24x = 216

x = 9

Answer: x + 10` is **not** a factor of `f(x) = 5x^3 + 60x^2 + 109x + 90`.

Step-by-step explanation: To determine if `x + 10` is a factor of `f(x) = 5x^3 + 60x^2 + 109x + 90`, we can use the Factor Theorem. The Factor Theorem states that if `f(a) = 0`, then `x - a` is a factor of `f(x)`.

In this case, we want to determine if `x + 10` is a factor of `f(x)`, so we can let `a = -10` and evaluate `f(-10)`:

`f(-10) = 5(-10)^3 + 60(-10)^2 + 109(-10) + 90`

`= -5000 + 6000 - 1090 + 90`

`= -1000`

Since `f(-10) ≠ 0`, we can conclude that `x + 10` is **not** a factor of `f(x) = 5x^3 + 60x^2 + 109x + 90`.

Answer:

The area is 92 square yards.

Step-by-step explanation:

We can decompose this figure into a rectangle and a triangle.

First, we can find the area of the rectangle.

A(rect) = length × width

A(rect) = 10 × 8

A(rect) = 80 yd²

Next, we can find the area of the triangle.

A(triangle) = (1/2) × base × height

[tex]A(\text{triangle}) = \dfrac{1}{2} \, (13 - 10) \times 8[/tex]

[tex]A(\text{triangle}) = \dfrac{3}{2} \times 8[/tex]

[tex]A(\text{triangle}) = 12 \text{ yd}^2[/tex]

Finally, we can add the two shapes' areas to get the area of the entire figure.

A = A(rect) + A(triangle)

A = 80 yd² + 12 yd²

A = 92 yd²

Answer: 92 yd²

Step-by-step explanation:

Decomposition means to break the shape into parts, but it's not necessary to break apart.

This is a trapezoid turned sideways A=1/2(b1+b1)h

b1=10

b2=13

h=8

A=1/2(10+13)8 =92 yd²

if you decompose, you can make the top a triangle and bottom a rectangle.

A(triangle) = 1/2(b)(h)     b=3   h=8

                 1/2(b)(h)

                 = 12

A(rectangle)=bh     b=10     h=8

                  =10*8

                   =80

Add the 2 and you get 92 again
