Rom4ik [11]

Answer:

The value of N is 12 sq cm.

Step-by-step explanation:

1. Find the greatest common factor of 35 and 42 to find the length (horizontal). The GCF is 7.

2. The horizontal length of the 35 and 42 sq cm is 7, and the heights are 5 and 6 respectively.

3. Moving on tot he 10 sq cm rectangle, since the height of just that one rectangle is and 10/5 is 2, the horizontal length is 2.

4. For n, the horizontal length is 2 and the height is 6. 2 X 6 is 12 sq cm.

We have a right triangle that has am 8 meter and 21 meter leg .Find the hypotenuse

Serjik [45]

Answer:

hypotenuse is 22.47 m

Step-by-step explanation:

The length of both legs of a right angle triangle are 8m and 21 m

We need to find the hypotenuse

To find hypotenuse we use Pythagorean theorem

Hypotenuse is AC and other two legs are AB and BC

$AC^2 = AB^2 + BC^2$

Hypotenuse ^2 = 8^2 + 21^2

hypotenuse = $\sqrt{8^2 + 21^2}$

= $\sqrt{64 + 441}$

= $\sqrt{505}$

= 22.47

So the length of the hypotenuse is 22.47 m

The weather forecaster says that the probability of rain on Saturday is 20% and the probability of rain on Sunday is 30%. a. Can

Annette [7]

Answer:

0.44

Step-by-step explanation:

given that the weather forecaster says that the probability of rain on Saturday is 20% and the probability of rain on Sunday is 30%.

It is common sense to know that Saturday and Sunday are independent of the other

Hence Probability that it rains on both days = 0.2*0.3=0.06

Since for independent events joint probability is the product of probabilities

required probability

= probability of rain over the weekend (Saturday or Sunday

= P(Sunday)+P(Saturday) -P(both)

= $0.2+0.3-0.06\\=0.44$
