Answer:

Probability that the product is an odd number =  [tex]\frac{1}{7}[/tex]

Step-by-step explanation:

Given - Patryk has 7 cards.  There is a number on each card.  2 3 4 5 6 7 8

            Patryk takes two of the cards at random.  He works out the product  

            of the numbers on the two cards.

To find - Work out the probability that the product is an odd number.

Proof -

As we know that Product of two numbers is odd iff both the numbers are odd.

So, we have to find the probabilty that both the card that Patryk choose is odd

Now,

Total number of cards = 7

Total number of odd cards = 3

So, Probability = ³C₂ / ⁷C₂

                       = [tex]\frac{3!}{2! (3-2)!}. \frac{2! (7 - 2)!}{7!}[/tex]

                      = [tex]\frac{3!}{2! (1)!}. \frac{2! (5)!}{7!}[/tex]

                      = [tex]\frac{3!}{(1)!}. \frac{ (5)!}{7.6.5.4.3!}[/tex]

                      = [tex]\frac{ 5.4.3.2.1}{7.6.5.4}[/tex]

                      = [tex]\frac{1}{7}[/tex]

∴ we get

Probability that the product is an odd number =  [tex]\frac{1}{7}[/tex]

Answer:

He multiplyed 3x8 and 5x8 when it should be 3x8 and 5x1 because you but 1 under the 8 to make it into a  fraction.

Step-by-step explanation:

Given:

[tex]\cos \angle A=\dfrac{342}{1000}[/tex]

To find:

The measure of angle A to the nearest degree.

Solution:

We have,

[tex]\cos \angle A=\dfrac{342}{1000}[/tex]

It can be written as

[tex]\angle A=\cos ^{-1}\dfrac{342}{1000}[/tex]

[tex]\angle A=70.00123^\circ[/tex]

[tex]\angle A=70^\circ[/tex]

Therefore, the measure of angle A to the nearest degree is 70 degrees.

Step-by-step explanation:

pi r^2

22/7 * 5^2

Answer:

area = 78.540 cm ^2

Step-by-step explanation:

area = Pi (radius^2)

area = 3.14159(5^2) = 3.14159(25) = 78.5397

Answer:

Step-by-step explanation:

You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.

You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.

That leaves you with one unknown angle. ? = 180°-40°-55° = 85°

Answer:

8/15

Step-by-step explanation:

Unit rate is 8 / 15 acres per day.

"Work is defined as when force is applied on an object and it gets move in particular direction."

According to the question,

Group of workers plant  2/ 5 acres  in 3 /4 days

3 / 4 days = 2/ 5 acres

1 day =  [tex]\frac{2}{5}[/tex] × [tex]\frac{4}{3}[/tex]

⇒ 1 day = 8 / 15 acres

Hence, Unit rate is 8 / 15 acres per day.

Answer:

y = (2/3)x - 2

Step-by-step explanation:

The equation of this line is y = (2/3)x - 2, where m is the given slope and -2 is the given y-intercept.  We need only plug in the given values for m and b.

Answer:

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

Step-by-step explanation:

This is the slope-intercept form. The slope-intercept form is written as y = mx + b where m is the slope and b is the y-intercept. The y and x stay as they are.

I hope this was what you were looking for.

Answer:

(0,1)

Step-by-step explanation:

0 because its intercept at 0 x-axis

1 because its intercept at 1 y-axis

also it is written in this way (0,1) because we write first the number on x-axis then y-axis
