Answer:

11.0 cm

P=38 cm

38/3=12.67cm length of one side

Base of triangle = 12.67/2 =6.34 cm

Use formula a^2+b^2=c^2

6.34^2+x^2=12.67^2\\\\=11.0 cm

x = altitude of triangle

kenny6666 [7]
Answer: It will take 10 minutes.

Explanation:

Cone A: 2.5mL x 10 minutes = 25 mL of ice cream falls in 10 minutes. 30mL-25mL=5mL

Cone B: 1.5mL x 10 minutes = 15 mL of ice cream falls in 10 minutes. 20mL-15mL=5mL

in 10 minutes, they’ll both be at 5mL

Let X have the probability mass function P(X = −1) = 1 2 , P(X = 0) = 1 3 , P(X = 1) = 1 6 Calculate E(|X|) using the approaches
Studentka2010 [4]

Answer:

Step-by-step explanation:

From the given information:

Note that the possible values of Y are 0 and 1 because;

y = 0 if X = 0 and y = 1 if X = ±1

∴

P(Y =0) = P(X = 0) =\dfrac{1}{3}

P(Y = 1) = P(X = -1  \ or \ 1) \\ \\ = P(X = -1) + P(X = 1)

= \dfrac{1}{2}+ \dfrac{1}{6}

=\dfrac{3+1}{6}

= \dfrac{2}{3}

b)

E(|X|) = \sum |x| P(X=x) = ( 1 \times \dfrac{1}{2}) + ( 0\times \dfrac{1}{3}) + ( 1 \times \dfrac{1}{6})

= \dfrac{2}{3}
