Find the missing probability in the table below.

1 answer:

7 0

X 1 2 3 4
p(x) 0.40 0.20 0.15 ?

If the items are only 4. The total of the probability must be 1 or 100%

1 - 0.40 - 0.20 - 0.15 = 0.25

The probability of 4 is 0.25.

A snail is moving along a path that is 4 meters long. The snail moves at an average rate of 3 3/10 inches per minute. Question 1

Troyanec [42]

Answer: The length of the path = 157 inches { approx}

Step-by-step explanation:

Given: The length of the path = 4 meters

1 meter = 100 centimeters

So 4 meters = 400 centimeters

Also 1 in. ≈ 2.54 cm

$\Rightarrow\ 1 cm = \dfrac{1}{2.54}\ in.$

Now, $\text{ 400 centimeters}=400\times\dfrac{1}{2.54}\text{ inches}$

$=157.480314961\approx 157 \ \ \ \ \ \text{ [Rounded to the nearest inch.]}$

Hence, the length of the path = 157 inches { approx}

Who knows this, Find m∠UTS, if m∠UTV=x+15, m∠VTS=140∘, and m∠UTS=15x+15

kakasveta [241]

Answer:

165

Step-by-step explanation:

First, m<UTS=m<UTV+m<VTS by Angle Addition Postulate. Then, you substitute all the values that you provided for the angles. 15x+15=x+15+140. You then solve for x.

15x+15=x+155

14x=140

x=10

You then plug back in 10 for X in the value of m<UTS. 15(10)+15=165
