Answer:

$342$

Step-by-step explanation:

The probability of heads landing is 0.43.

The probability of tails landing is 1-0.43=0.57.

Azmol throws the coin 600 times, so:

$600 \times 0.57$

$=342$

If n is an integer, which conjecture is not true about 2n– 1? A. 2n– 1 is odd if n is positive. B. 2n– 1 is always even. C. 2n–

VladimirAG [237]

B.

Let's simply look at each conjecture and determine if it's true or false.

A. 2nâ€“ 1 is odd if n is positive: Since n is an integer, 2n will always be even. And an even number minus 1 is always odd. Doesn't matter if n is positive or not. So this conjecture is true.

B. 2nâ€“ 1 is always even: Once again, 2n will always be even. So 2n-1 will always be odd. This conjecture is false.

C. 2nâ€“ 1 is odd if n is even: 2n is always even, so 2n-1 will always be odd, regardless of what n is. So this conjecture is true.

D. 2nâ€“ 1 is always odd: 2n will always be even. So 2n-1 will always be odd. Once again, this conjecture is true.

Of the 4 conjectures above, only conjecture B is false. So the answer is B.

Elainas old bicycle had tires with a 12-inch diameter her new bicycle had tires with a 16-inch diameter what is the difference i

mr Goodwill [35]

Answer:

The difference between the circumference of the tires is 12.56 inches.

Step-by-step explanation:

Given:

Diameter of old bicycle tires = 12 inch

Diameter of new bicycle tires = 16 inch

We need to find the difference in circumference of the tires.

Solution:

First we will find the circumference of Old bicycle tires.

Circumference can be calculated by π times diameter.

Circumference of Old bicycle tire = $\pi \times 12 = 37.68\ in$

Now we will find the circumference of new bicycle tire.

Circumference of New bicycle tire = $\pi \times 16 = 50.24\ in$

Now to find the difference between the circumference of the tires we will subtract Circumference of New bicycle tire from Circumference of Old bicycle tire we get;

framing in equation form we get;

difference between the circumference of the tires = $50.24-37.68 =12.56\ in$

Hence The difference between the circumference of the tires is 12.56 inches.

Spiro travels 140km per week travelling to and from work. If Spiro works 5 days per week. What distance is his work from home?

Ber [7]

Answer:

14 km

Step-by-step explanation:

<u>1) look at the information you are given:</u>

140 km total (<em>to and from work</em>)

Note that this number includes both the distance to work and the distance from work.

He works 5 days a week.

<u>2)Figure out the distance he travels within one day</u>

This means that you should take the 140 km and divide it by 5 in order to find out the amount of km he travels each day.

28 km is the amount of KM he travels each DAY.

<u>3) Figure out the distance from work to home </u>

From this point, it is important to note the question is asking for <u>the distance his work is from home.</u>

Each day, he must travel 2 times: he must go to work and go from work to home, which are both the same distance.

This means that in order to get only the distance from work to home, you must divide by 2.

A rectangle has a length of x+2, a width of 7, and a perimeter of 32. The value of x is ?

beks73 [17]

Perimeter = sum of all sides

32 = 2(x+2) + 2(7)
32 = 2x+4 + 14
32 = 2x+18
14 = 2x
/2 /2

7 = x
