Assume that random guesses are made for nine multiple choice questions on an SAT test, so that there are nequals9 trials, each

balu736 [363]

Answer:

$P(X=0)=(9C0)(0.55)^9 (1-0.55)^{9-0}=0.000757$

$P(X=1)=(9C1)(0.55)^9 (1-0.55)^{9-1}=0.0083$

$P(X=2)=(9C2)(0.55)^9 (1-0.55)^{9-2}=0.0407$

$P(X=3)=(9C3)(0.55)^9 (1-0.55)^{9-3}=0.1160$

And adding we got:

$P(X < 4) = 0.000757 +0.0083+0.0407 +0.1160= 0.2626$

Step-by-step explanation:

Let X the random variable of interest "number of correct answers", on this case we now that:

$X \sim Binom(n=9, p=0.55)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find this probability:

$P(X < 4) =P(X=0) +P(X=1) +P(X=2) +P(X=3)$

And we can find the individual probabilities:

$P(X=0)=(9C0)(0.55)^9 (1-0.55)^{9-0}=0.000757$

$P(X=1)=(9C1)(0.55)^9 (1-0.55)^{9-1}=0.0083$

$P(X=2)=(9C2)(0.55)^9 (1-0.55)^{9-2}=0.0407$

$P(X=3)=(9C3)(0.55)^9 (1-0.55)^{9-3}=0.1160$

And adding we got:

$P(X < 4) = 0.000757 +0.0083+0.0407 +0.1160= 0.2626$

Please help me!!!!!!!!!!!!!!!!

This is an equation in the form of y = kx. Where y is the dependent variable, x is the independent variable, and k is the constant of proportionality.

In this case 7 would be your constant of proportionality

A recipe for cookies calls for 2 cups of flour, 1/2 teaspoon of baking soda, 1/2 teaspoon of salt, 3/4 cup of butter, 1.5 cups o

Vesnalui [34]

Answer:

1340 mL

Step-by-step explanation:

There are ...

2 + 3/4 + 1.5 + 1.25 = 5.5

cups of ingredients, and ...

1/2 + 1/2 + 3 = 4

teaspoons of ingredients. Each teaspoon is 1/3 of 1/16 of a cup, so is 1/48 of a cup.

Altogether, the volume of ingredients is ...

5.5 + 4/48 cups = 5 7/12 cups

= (5 7/12)×(240 mL/cup) = 1340 mL
