Answer:

4 times

Step-by-step explanation:

Sample space :

6 sided cube = (1, 2, 3, 4, 5, 6)

Coin = (H, T)

Probability = required outcome / Total possible outcomes

Probability of head (H) = P(H) = 1 /2 = 0.5

Probability of 3 = P(3) = 1 /6 = 0.166666

Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333

Hence, expected number of times this is likely to occur in 48 tries :

0.083333 * 48 = 4

Answer:

You divide $3.20 by 16, and this gives you 0.2- therefore, the trail mix costs $0.20 pr ounce.

Answer:

60 hours

Step-by-step explanation:

We are given;

Initial amount: A_o = 64 mg

Half life; T_½ = 15 hours

Amount left: A = 4 mg

To get the time that 4 mg of Sodium-24 remain, we will use the formula;

A = A_o(½^(t/T_½))

Where t is the time that 4 mg of Sodium-24 remain.

Thus;

4 = 64 × ½^(t/15)

Divide both sides by 64 to get;

4/64 = 2^(t/15)

0.0625 = ½^(t/15)

In 0.0625 = (t/15) In 0.5

-2.7726 = (t/15) × -0.6931

t = (-2.7726 × 15)/-0.6931

t = 60 hours

Answer:

c

Step-by-step explanation:

Given the2 equations

y = x + 4 → (1)

x + y = 2 → (2)

Substitute y = x + 4 into (2)

x+ x + 4 = 2

2x + 4 = 2 ( subtract 4 from both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

Substitute x = - 1 into (1) for corresponding value of y

y = - 1 + 4 = 3

solution is (- 1, 3 ) → c

Answer:

  a) 9/2 = 4.5, bushels per hour

  b) (3, 10), (6, 20), (9, 30), (12, 40)

  c) Shawn

Step-by-step explanation:

a) The line goes through the grid point (4, 18), so its slope is ...

  18/4 = 4.5 . . . . slope = "unit rate"

The units are (y-units)/(x-units) = bushels/hour.

__

b) You have correctly filled in the table.

Time-values are 3, 6, 9, 12.

Fruit values are 10, 20, 30, 40.

The unit rate for Carla is ...

  10 bu/(3 h) = 3 1/3 bushels/hour ≈ 3.33 bushels/hour

__

c) Shawn's unit rate of 4.5 bushels per hour is greater than Carla's unit rate of 3.33 bushels per hour. Shawn picked fruit at a faster pace.

Step-by-step explanation:

Answer:

13a:   Measure of angle 1 is 120 degrees

13b:   Angle 2 is 60 degrees

Step-by-step explanation:

Angle 1 is alternate exterior (so in a parallel pair they are equal) to the angle on line m given as 120 deg.

Angle 2 is 180 minus 120= 60   Sum of the two angles must equal 180.

Step-by-step explanation:

plz mark my answer as brainlist plzzzz vote me also

Answer:

100°

Step-by-step explanation:

Ok so it looks overwhelming at first, but you just need to make sections and break it down

You are looking for h°, so you want to make it a triangle

The angles of this triangle would be h°, 40°, and x°

You can find x° by using the 140° on the same line

it is a straight line, so that means its angle is 180°

180° - 140° = 40°

x° = 40 °

so now you know that the angles in the triangle are h°, 40°, and 40°

Every triangle has angles that measure to 180°

180° - 40° - 40° = 100°

h° = 100°

Answer:

$225

Step-by-step explanation:

Frist, we need to figure out how much Rachel makes per hour. For 9 hours of work, she makes $67.50

67.5 / 9 = 7.5

Rachel makes $7.50 per hour

Now we can add up all the hours she worked.

5 hours a day for 6 days

5 x 6 = 30

She worked 30 hours at a rate of $7.50 per hour

7.5 x 30 = 225

She earned $225

Step-by-step explanation:

12y = -2x - 192

y = -1/6 x - 16

Answer:

answer of 2a)

He started with $24 and spent $16. Let a represent his account balance after he bought the notebook and pens. Then

24–16=a

His new account balance is $8.

He has $8 in his account and then he deposited b dollars. His account balance is now $28. Then

8+b=28

His deposited $20 in his account.

He has $28 and spent $34. Let c represent his account balance after he bought the book. Then

28–34=c

His new account balance is -$6.

He started with an account balance of -$6 and paid the debt off so his account balance is 0. If d is the amount money he deposited to pay off his debt, then

−6+d=0

He deposited $6.

answer of 2b)

If he spends more than he has in his account, then we are subtracting a bigger number from a smaller number, and the result is negative. ... The opposite of a positive number is a negative number, so it makes sense to represent his account balance with a negative number when he owes money to the bookstore.

Answer:

equal to

Step-by-step explanation:

The y intercept is when x = 0.

In the function y=-2x+8, when x=0, y=8.

In the graph, when x=0, y=8. You can see on the x axis 0 is in the middle, and if you move up the y axis, you see the line intersects y=8.

Thus both have the same y intercepts of 8.

please give thanks :)

Answer:

95

Step-by-step explanation:

The equation is

x×2=285-x

3x=285

x=95

Answer:

x = 75°

Step-by-step explanation:

There are many Circle Geometry Rules. We will be using the following:

The angle at the centre of the circle is twice the angle at the circumference.

x = the angle opposite 285 - x.

This means that 360 - (285 - x) = 2x

360 - 285 + x = 2x

75 + x = 2x

We can simplify this by taking away x from both sides.

75 = x

We can check this by substituting x into the orginal equation.

360 - (285 - x) = 2x

360 - (285 - 75) = 2 * 75

360 - 210 = 2 * 75

150 = 2*75

150 = 150

Answer:

343 cube meters of air

Answer:

Options (1) and (3)

Step-by-step explanation:

Option (1)

f(x) = x²+ 3

We can rewrite the function in the equation form as,

y = x² + 3

By interchanging y by x,

x = y² + 3

Now we solve it for y,

y² = x - 3

y = ±√(x - 3)

So the inverse function is,

[tex]f^{-1}(x)=\pm \sqrt{x-3}[/tex]

It's a function.

Option 2

d(x) = -9

Equation form of the function is,

y = -9

Replacing y by x,

x = - 9

Therefore, inverse function will be,

x = -9

Inverse is not a function

Option 3

m(x) = -7x

Equation form of the function,

y = -7x

Interchanging y by x,

x = -7y

Now solve for x,

y = [tex]-\frac{1}{7}x[/tex]

So the inverse function will be,

[tex]m^{-1}(x)=-\frac{1}{7}x[/tex]

Inverse is a function.

Option 4

p(x) = |x|

As this function not a one to one function inverse function is not possible.

Inverse of |x| is not a function.
