Lucy makes 4/7 of a dress in 3/4. How many dresses does she make in one hour

GREYUIT [131]

Answer:

3/7 of a dress in one hour

Step-by-step explanation:

(4/7)/(3/4)=x/(4/4)

(4/7)(4/3)=x/1

cross product

4/3*x=(4/7)(1)

4/3x=4/7

x=(4/7)/(4/3)

x=(4/7)(3/4)

x=3/7

A basketball player is fouled while attempting to make a basket and receives two free throws. The opposing coach believes there

zzz [600]

Answer:

$P(X = 0) = 0.64$

$P(X = 1) = 0.11$

$P(X = 2) = 0.25$

b) 0.75 = 75% probability that he makes no more than one of the shots

Step-by-step explanation:

We have these following probabilities:

64% = 0.64 probability that he misses both shots, that is, makes none of them.

11% = 0.11 probability that he makes one shot.

25% = 0.25 probability that he makes both shots.

a. Construct the appropriate probability distribution. (Round your answers to 2 decimal places.)

Binomial probability distribution, in which P(X = x) is the probability of making x shots. So

$P(X = 0) = 0.64$

$P(X = 1) = 0.11$

$P(X = 2) = 0.25$

b. What is the probability that he makes no more than one of the shots? (Round your answer to 2 decimal places.)

$P(X \leq 1) = P(X = 0) + P(X = 1) = 0.64 + 0.11 = 0.75$

0.75 = 75% probability that he makes no more than one of the shots

50 points.

Sphinxa [80]

Answer:

Step-by-step explanation:

Using the rules of exponents

$(a^m)^{n}$ = $a^{mn}$

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$

Given

$(\frac{1}{x^{(a-b)}) } ^{a+b}$ × $(\frac{1}{x^{b+a}) } ^{b-a}$

= $\frac{1}{x^{(a-b)(a+b)} }$ × $\frac{1}{x^{(b+a)(b-a)} }$

= $\frac{1}{x^{(a^2-b^2)} }$ × $\frac{1}{x^{(b^2-a^2)} }$

= $\frac{1}{x^{(a^2-b^2+b^2-a^2)} }$

= $\frac{1}{x^{0} }$

= $\frac{1}{1}$

= 1

Which expression below is equivalent to 2x + 8?

mash [69]

Answer: D) x+4+x+4

The two x terms combine to x+x = 2x

The other pair of like terms, the constants, add to 4+4 = 8

Overall we get 2x+8

2x+8 is also equivalent to 2(x+4) when you factor out the GCF 2.
