Step-by-step explanation:

Answer:

1. 1/4

2. 1/2

Step-by-step explanation:

If there are equal numbers of males and females, we can simplify that by saying there's one male and one female for each coat color.

1. What's the probability that both are males?

Well, there's a 1/2 chances the light-colored coat bear is a male and there's also a 1/2 chances the dark-colored coat bear is a male.  So, we can make this reference table:

Light             Dark

Male             Male

Male             Female

Female         Male

Female         Female

As you can see, the probability that both of the spotted bears are males is 1/4 (1/2 * 1/2).

2. If the light-colored bear, what are the odds both are males?

If we know for sure the light-one is male, then there's 1/2 chances the other is too, refer to the table above to verify.

Answer:

£480

Step-By-Step Explanation:

x = the original price of a computer

£x = 100% of the original price

The price of a computer was decreased by 30% to £336.

This means:

£336 = 100% - 30%

£336 = 70% of the original price

From this, we will find 1% of the original price.

£336 ÷ 70 = 1%

£4.8 = 1%

Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.

£4.8 × 100 = 100%

£480 = 100%

Therefore, the original price of a computer = £480

ANSWER

[tex]x = 4[/tex]

and

[tex]y = - 1[/tex]

EXPLANATION

Line s has equation:

y=x-5

And line t has equation:

[tex]y = - \frac{3}{4}x + 2[/tex]

We equate the two equations to get:

[tex]x - 5 = - \frac{3}{4} x + 2[/tex]

Multiply through by 4

[tex]4x - 20 = - \frac{3}{4} x \times 4 + 2 \times 4[/tex]

[tex]4x - 20 = - 3 x + 8[/tex]

[tex]4x + 3x = 8 + 20[/tex]

7x=28

[tex]x = \frac{28}{7} = 4[/tex]

[tex]y = 4 - 5 = - 1[/tex]

Answer:

(4, -1) is the solution of the system of equations.

Step-by-step explanation:

A system of equations consists of a line y = x - 5 and a line passing through two points (0, 2) and (8, -4)

And the equation of that passes through these points will be [tex]y=-\frac{3}{4}x+2[/tex]

Now we have to find the solution of the system of linear equations.

By equating both the equations

x - 5 = [tex]-\frac{3}{4}x+2[/tex]

Now we multiply this equation by 4

4(x - 5) = -3x + 4×2

4x - 20 = -3x + 8

4x + 3x = 8 + 20

7x = 28

x = 4

Now we put x = 4 in the equation y = x - 5

y = 4 -5

y = -1

Therefore, (4, -1) is the solution of the system of equations.

Answer:

t=-148+1/1.5740740740741

Step-by-step explanation:

(t)=-0.32+2.7t+253

We move all terms to the left:

(t)-(-0.32+2.7t+253)=0

We add all the numbers together, and all the variables

t-(2.7t+252.68)=0

We get rid of parentheses

t-2.7t-252.68=0

We add all the numbers together, and all the variables

-1.7t-252.68=0

We move all terms containing t to the left, all other terms to the right

-1.7t=252.68

t=252.68/-1.7

t=-148+1/1.5740740740741

Answer: t=-148+1/1.5740740740741

Step-by-step explanation: (t)-(-0.32+2.7t+253)=0

                                              t-(2.7t+252.68)=0

                                               t-2.7t-252.68=0

                                                 -1.7t-252.68=0

                                                  -1.7t=252.68

                                                   t=252.68/-1.7

                                                     t=-148+1/1.5740740740741

Answer:

Therefore, the plant that grew at a faster rate would be Megan’s at 2.5 inches per week.

Step-by-step explanation:

Megan's rate = 12 - 4.5 / 4 -1 = 2.5 inches per week

Suzanne's rate = 11 - 5 / 4-1 = 0.5 inches per week

Without the actual growth measurements, we cannot make a comparison or identify which plant grew faster.

Using the examples:

Suzanne's plant grew at a faster rate (1.5 inches/week) compared to Megan's plant (1 inch/week).

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To determine whose plant grew at a faster rate and what was the rate, we need information about the growth of their plants over the four-week period.

Without this information, we cannot determine the rate of growth or compare the rates of growth of their plants.

Assuming that we have the required information about their plant growth, we can compare the rates of growth of their plants by calculating the average weekly growth rate of each plant.

The plant with a higher average weekly growth rate grew at a faster rate.

For example:

If Megan's plant grew by 4 inches over four weeks, its average weekly growth rate would be:

The average weekly growth rate of Megan's plant = (Total growth in 4 weeks) / (Number of weeks)

= 4 inches / 4 weeks

= 1 inch/week

Similarly,

If Suzanne's plant grew by 6 inches over four weeks, its average weekly growth rate would be:

The average weekly growth rate of Suzanne's plant = (Total growth in 4 weeks) / (Number of weeks)

= 6 inches / 4 weeks

= 1.5 inches/week

In this example:

Suzanne's plant grew at a faster rate (1.5 inches/week) compared to Megan's plant (1 inch/week).

Thus,

Without the actual growth measurements, we cannot make a comparison or identify which plant grew faster.

Answer:

D is false

Step-by-step explanation:

f(x) = -2x2 + 4x + 6 should be written with a " ^ " to indicate exponentiation:

f(x) = -2x^2 + 4x + 6.

Because of the - sign, we know that the graph of this function opens down, so there is a maximum at the vertex.  We can determine the x-value at the vertex by using the formula x = -b/(2a), which here is x = -4/(2*-2), or 1.

Evaluating f(x) = -2x^2 + 4x + 6 at x = 1, we get -2 + 4 + 6, or 8.  So statement A is true:  there's a max at (1, 8).  This is also the vertex of the graph.

Let's now look at C and D.  We evaluate f(x) at x = 3 and x - 2.  If the output (y) value is 0, we know we have an x - intercept:

f(3) = -2(9) + 4(3) + 6 = 0.  Yes, C is true, (3, 0) is an x-intercept.

f(-2) = -2(4) - 8 + 6 is not 0.  Therefore D is false; (-2, 0) is not an x-intercept.

Look at B:  Let x = 0 and find y:  it's 6.  Thus, (0, 6) is the y-intercept.  B is true.
