40% = 0.40

0.40 x 40 = 16

Answer:

16

Step-by-step explanation:

.40 x 40 = 16

Think of 4 times 4 which is 16, and then add the two zeros at the end to have 1600.0

Move the decimal place at the end of 1600.0 two to the left because 40% =0.4 is 40.0 moved two the left as well.

Hope it helps!

A basketball player has made 6060​% of his foul shots during the season. Assume the shots are independent. ​
motikmotik

Answer:

a) 2.5 shots

b) 59.4 shots

c) 4.87 shots

Step-by-step explanation:

Probability of making the shot = 0.6

Probability of missing the shot = 0.4

a) The expected number of shots until the player misses is given by:

E(X) = \frac{1}{P(X)}=\frac{1}{0.4}  \\E(X) = 2.5\ shots

The expected number of shots until the first miss is 2.5

b) The expected number of shots made in 99 attempts is:

E=99*0.6\\E=59.4\ shots

He is expected to make 59.4 shots

c) Let "p" be the proportion shots that the player make, the standard deviation for n = 99 shots is:

s=\sqrt{n*p*(1-p)}\\ s= 4.87\ shots

The standard deviation is 4.87 shots.

Ayuda Estoy En Examen:(

Usando la división de términos con la <u>misma base y diferentes exponentes</u>, se encuentra que la expresión simplificada está dada por:

k^{-5}l^{-8}n^6a^{-4} = \frac{n^6}{k^5l^8a^4}

<h3>¿Cómo dividir términos con la misma base y diferentes exponentes?</h3><h3 />

Para hacer la división, mantenemos la base y restamos los exponentes.

En este problema, la división es dada por:

\frac{-k^6l^1n^9}{-k^{11}l^9n^3a^4}

Por lo tanto, el resultado es:

k^{6-11}l^{1-9}n^{9-3}a^{0-4} = k^{-5}l^{-8}n^6a^{-4} = \frac{n^6}{k^5l^8a^4}

Como tanto el numerador como el denominador son negativos, la división es positiva.
