Answer:

She collected 1 2/3 or [tex]1 \frac{2}{3}[/tex]  kilograms

Step-by-step explanation:

(2/3)s of 2 and 1/2

Make 2 1/2 into an improper fraction.

5/2

'Of' is the same thing as multiplying. So, (2/3)*5/2

2*5 to get 10

3*2 to get 6

10/6. 10/6 reduced to a proper fraction is 1 2/3.

Using the probability concept, it is found that:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For the experimental probability, the numbers of outcomes are taken from previous trials, hence considering the name Karen was chosen 19 times out of 123, we have that:

[tex]p_E = \frac{19}{123} = 0.1545[/tex]

For the theoretical probability, the number of outcomes are taken from the "theory", that is, before the trials, hence considering that Karen is one out of 8 names:

[tex]p_T = \frac{1}{8} = 0.125[/tex]

If the number of names in the hat was different, the total number of outcomes would for the theoretical probability would be different, hence with less names the probabilities would increase, with more names the probabilities would decrease.

Answer:

96 cm^2

Step-by-step explanation:

Volume of a cube =(side)^3=64 cm^3.

(side)^3= (4 cm.)^3

or side =4 cm.

Surface area =6×(side)^2..

=6×4×4 cm^2=

96 cm^2. , Answer

Answer:

Step-by-step explanation:

Volume of cube = 64 m³

Side³ = 64

Side = ∛64 = ∛2*2*2*2*2*2

Side = 2*2 = 4 m

Surface area = 6side² = 6* 4² = 6*4*4

                     = 96 m²

Answer:

r = 13

Step-by-step explanation:

As the vertically opposite angles are equal,

8r + 6 = 9r - 7

Now you can find the value of r.

8r - 9r = -6 - 7

-r = -13

r = 13

Answer:

Suppose the closest point is at p=(x0,y0), and set q=(−2,−3). Then the tangent to the parabola at p is perpendicular to ℓ, the line through p,q. and we end up numerically computing the roots from here.

Answer:2y>x  or x<2y

x+y < 500

The points satisfying the 2nd inequality is a triangle bordered by the x and y axes and a downward sloping line connecting points (0,500) and (500,0)

the 1st inequality is half a plane, above the line x=2y or a  line through the origin, with slope 1/2

the two overlap in a triangle bordered by the y axis, the line x+y=500 and the line x=2y

It's a triangle with vertices (333 1/3, 166 2/3) (0,500) and the origin (0,0)

Step-by-step explanation:

[tex] - 24 > x + 4[/tex]

[tex] - 28 > x[/tex]

Answer:

Step-by-step explanation:

So what you need to do is take the two points (1, -5) and (3, -1) and subtract them. You take y of the second group and subtract y of the first group.

-1 - (-5) = 4

Now you do the first numbers in each group with the second set being the number you subtract from.

3 - 1 = 2

Now you do [tex]\frac{Rise}{Run}[/tex]. Rise = 4 Run = 2

[tex]\frac{4}{2}[/tex] = 2

Now the second part is saying y = 3x + c with your first set of numbers being x and y.

x = 1

y = -5

-5 = 3(1) + c

-5 = 3 + c

Subtract 3 from -5

-8 = c

The final answer is:

y = 3x - 8

Just simple addition and subtraction!

Answer:

69920

Step-by-step explanation:

If you are without a calculator, there is a trick you can do that could make this easier for you.

Instead of multiplying by 95 right away, instead, try multiplying by 100.

736 x 100 = 73600

With that, subtract by the product of 736 x 5 (which equals 3680)

With this, we can use what we know to say that

736x95 = 736x100 - 736x5; plug in what we got as our products and we're given

736x95 = 73600 - 3680 = 69920

Answer:

Step-by-step explanation:

Long multiplication means you're doing multiplication by hand. The traditional method, or Standard Algorithm, involves multiplying numbers and lining up results according to place value. These are the steps to do long multiplication by hand:

Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand.

Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top number

Write the answer below the equals line

If that answer is greater than nine, write the ones place as the answer and carry the tens digit

Proceed right to left. Multiply the ones digit of the bottom number to the next digit to the left in the top number. If you carried a digit, add it to the result and write the answer below the equals line. If you need to carry again, do so.

When you've multiplied the ones digit by every digit in the top number, move to the tens digit in the bottom number.

Multiply as above, but this time write your answers in a new row, shifted one digit place to the left.

When you finish multiplying, draw another answer line below your last row of answer numbers.

Use long addition to add your number columns from right to left, carrying as you normally do for long addition.

Answer:

172 = y

Step-by-step explanation:

Using PEMDAS(parentheses, exponents, multiplication, division addition subtraction.)

Given:

12 x 12 + 3 x 8 - 10 + 19 = y

12x 12 = 144

3 x 8  = 24

144 + 24 = 168

168 - 10 = 158

158 + 19 =

Answer:

   (a)  f(x) = -2x + 4

Step-by-step explanation:

The point (0, 4) in the table tells you the y-intercept is 4. Then the equation in slope-intercept form will be ...

  y = mx +b . . . . . m is the slope; b is the y-intercept

The answer must have the form ...

  y = mx +4

Only the first choice has the correct y-intercept.

You may notice that when x gets larger by 1, y decreases by 2. That means the slope is m = Δy/Δx = -2/1 = -2. Then the whole equation is ...

  y = -2x +4

Probabilities are used to determine the chances of events

The probability that the income is at least $100,000 is 0.106

From the table, we have the following parameters:

Salary 100 - 499 = 0.100

Salary >= 500 = 0.006

The probability that the income is at least $100,000 is then calculated as:

p = 0.100 + 0.006

Evaluate the sums

p = 0.106

Hence, the probability that the income is at least $100,000 is 0.106
