2 answers:

7 0

Since there is a negative exponent, you need to first convert that into a positive exponent which is going to be 1/4^5
Then, we can find out the answer by simply breaking apart the exponents into 5 groups of 4.
1/(4)(4)(4)(4)(4)

Alg 1 solving equations -12(-4 + p) = -48

Vilka [71]

Answer:

$p=8$

Step-by-step explanation:

$-12\left(-4+p\right)=-48$

Divide both sides by -12:-

 $\frac{-12\left(-4+p\right)}{-12}=\frac{-48}{-12}$

$-4+p=4$

Add 4 to both sides:-

$-4+p+4=4+4$

$p=8$

Find a direct relationship between x and y. x = 3t and y = 2t + 7

ikadub [295]

Answer:

y = $\frac{2}{3}$ x + 7

Step-by-step explanation:

Given

x = 3t ( divide both sides by 3 )

$\frac{1}{3}$ x = t

Substitute this value into y = 2t + 7

y = 2 × $\frac{1}{3}$ x + 7 = $\frac{2}{3}$ x + 7

The probability that an individual is left-handed is 0.170. In a class of 46 students, what is the probability of finding five

ruslelena [56]

Answer:

The probability of finding five left-handers in the sample is P(x=5)=0.094.

Step-by-step explanation:

We can model this variable with a binomial distribution, with parameters n=46 (sample size) and p=0.170 (the probability that an individual is left-handed).

The probability that k individuals are left-handed in the sample can be calculated as:

$P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}\\\\\\P(x=k) = \dbinom{46}{k} 0.17^{k} 0.83^{46-k}\\\\\\$

Then, the probability of finding five left-handers in the sample is:

$P(x=5) = \dbinom{46}{5} 0.17^{5}\cdot 0.83^{41}=1370754*0.000142*0.000481=0.094\\\\\\$
