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:

[tex]m=\frac{8}{5}[/tex]

Step-by-step explanation:

Answer:  The slope is  -8/5

Step-by-step explanation:

Using the located points  (-1,4)     and  (4,-4)  we will find the difference in the y coordinates of the points and divide it by the difference in the  x coordinates of the same points.  

Difference in y:  4 - (-4)  =  8

Differecence in x  -1 - 4 = -5

Slope:    8/-5

Answer:

think what constant of proportionality is

Step-by-step explanation:

Answer:

breadth=16cm and length=32cm

Let breadth be X

According to question,

lengtg=2X

Now,

Perimeter=2(l+b)

or,96=2(2X+X)

or,96=2(3X)

or,96=6X

or,96/6=X

or,X=16cm.

length =32 cm and breadth =16 cm

Answer:

length = 32 cm, breadth = 16 cm

Step-by-step explanation:

let breadth be b then length is 2b, then

2b + 2(2b) = 96

2b + 4b = 96

6b = 96 ( divide both sides by 6 )

b = 16

Thus

breadth = 16 cm and length = 2 × 16 = 32 cm

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:

The initial bacteria population is 238

Step-by-step explanation:

Let us have the increase as an exponential equation

P(t) = I(1 + r)^t

where P(t) is the count at a particular time

r is the percentage increase

I is the initial population

t is the time

So for 5 minutes, we have

348 = I(1 + r)^5

For 20 minutes

1088 = I(1 + r)^20

Divide the second equation by the first

1088/348 = I(1 + r)^20/I(1 + r)^5

3.13 = (1 + r)^15

Take the ln of both sides

ln 3.13 = 15 ln (1 + r)

ln 3.13/15 = ln (1 + r)

0.0761 = ln (1 + r)

1 + r = e^0.0761

1 + r = 1.079

r = 1.079-1

r = 0.079 which is 7.9%

So per minute. we have an increase of 7.9%

So let’s get I by substituting

From;

348 = I(1 + 0.079)^5

348/1.079^5 = I

I = 237.9 which is 238 to the nearest whole number

Answer:

9

Step-by-step explanation:

270/30=9

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

Answer:

D

Step-by-step explanation:

Answer: 7 pounds

Step-by-step explanation: 1 3/4×4=7

Step-by-step explanation:

First no. is 12

Second no. is 8

Third no. of 25

Way 1 of grouping the numbers,

(12×8)×25

We can use associative law of multiplication as follows :

(a×b)×c = a×(b×c)

(12×8)×25 = (96) × 25

= 2400

Way 2,

12×(8×25) = 12 × 200

= 2400

Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.

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.

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
