Which expression is equivalent to 6^-3?
1/216 is the equivalent expression for the given exponent [tex]6^{-3}[/tex].
An algebraic expression is a mathematical expression involving mathematical operations, variables, numbers, and mathematical quantities and combinations of them.
A negative exponent is the reciprocal of the same exponent with a positive value.
The reciprocal of any number is given by the fraction with the number as denominator and 1 as the numerator.
Here the given negative exponent is given by,
[tex]6^{-3}[/tex]
The exponent with positive value of the given negative exponent is given by [tex]6^3[/tex]
Reciprocal of the above exponent with positive value is given by,
[tex]\frac{1}{6^3}[/tex]
So now Calculating the negative exponent we have,
[tex]6^{-3} = \frac{1}{ {6}^{3} } = \frac{1}{216} [/tex]
Hence the equivalent expression for the given negative exponent is 1/216.

Bricklayer Ben places 42 bricks per hour. Bricklayer Bob places 36 bricks per hour. Bricklayer Bob worked twice as many hours as Bricklayer Ben, and the two of them placed a total of 1254 bricks. How many bricks did Bricklayer Ben place
Bricklayer Ben placed a total of 462 bricks.
How to use equation to find the number of bricks placed?Bricklayer Ben places 42 bricks per hour.
Bricklayer Bob places 36 bricks per hour.
Let
x = number of hours worked by Bricklayer Bob
y = number of hours worked by Bricklayer Ben
Therefore,
x = 2y
42y + 36x = 1254
42y + 36(2y) = 1254
42y + 72y = 1254
114y = 1254
y = 1254 / 114
y = 11
Hence, Bricklayer Ben placed a total of 42 × 11 = 462 bricks.

In the diagram, O is the centre of the circle, BD = DC and PAB is a straight line. Prove that AD bisects the angle CAP.
Answer:
BAC=BDC(BDX)=30°
Step-by-step explanation:
We know that BD=OD.
But OD=OB= Radius of the circle.
Therefore
BD=OD=OB
BDO is equilateral triangle.
Angle DBO= 60°
Now let us take the intersecting point of CD and AB as X.
In triangle BDX,
BXD= 90°(BXD+BXC=180°, BXD+90°=180°, BXD=90°)
BXD+DBX+BDX=180°{Angle Sum Property}
90°+60°+BDX= 180°
BDX= 30°
We also know that,
BDC(BDX)= BAC (Angles lie on the same arc{BC} are equal in measure.
Therefore,
BAC=BDC(BDX)=30°
In a batch of 8,000 clock radios 4% are defective. A sample of 7 clock radios is randomly selected without replacement from the 8,000 and tested. The entire batch will be rejected if at least one of those tested is defective. What is the probability that the entire batch will be rejected?
Using the hypergeometric distribution, there is a 0.2486 = 24.86% probability that the entire batch will be rejected.
What is the hypergeometric distribution formula?The formula to find the hypergeometric distribution formula is
P(X=x)=P(x, N, n, K)[tex]=\frac{C_{k, x} C_{N-k, n-x} }{C_{N, n} }[/tex]
[tex]C_{n, x} =\frac{n!}{(n-x)!}[/tex]
The parameters are:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
For this problem, the values of the parameters are given as follows:
N = 8000, n = 7, k = 0.04 x 8000 = 320
The probability that the entire batch will be rejected is P(x≥1), given as follows: P(x≥1)=1-P(X=0)
In which,
P(X=0)=P(0, 8000, 7, 320)[tex]=\frac{C_{320, 0} C_{7680, 7} }{C_{8000, 320} }=0.7514[/tex]
Now, P(x≥1)=1-0.7514=0.2486
Therefore, 0.2486 = 24.86% probability that the entire batch will be rejected.

For what values of x will the function f(x) = 3x² + 13x - 10 equal zero?
Answer:
x = - 5 , x = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
the values of x that make f(x) zero are the zeros
to find the zeros let f(x) = 0 , that is
3x² + 13x - 10 = 0
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 10 = - 30 and sum = + 13
the factors are + 15 and - 2
use these factors to split the x- term
3x² + 15x - 2x - 10 = 0 ( factor the first/second and third/fourth terms )
3x(x + 5) - 2(x + 5) = 0 ← factor out (x + 5) from each term
(x + 5)(3x - 2) = 0
equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
3x - 2 = 0 ⇒ 3x = 2 ⇒ x = [tex]\frac{2}{3}[/tex]

since the equation (1) has equal roots
[tex]\Rightarrow b^2 - 4ac = 0 \newline\\\Rightarrow (-k)^2 - 4(1)(9) = 0\\ \newline\\\Rightarrow (k)^2 - 36 = 0 \newline\\\Rightarrow k^2 = 36 \newline\\\Rightarrow k = \pm 6[/tex]

Suppose 40% of American singers are Grammy award winners. If a random sample of size 743 is selected, what is the probability that the proportion of Grammy award winners will differ from the singers proportion by less than 3%
Using the normal distribution, it is found that there is a 0.905 = 90.5% probability that the proportion of Grammy award winners will differ from the singers proportion by less than 3%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].The proportion and the sample size are given, respectively, by:
p = 0.4, n = 743
Hence the mean and the standard error are given, respectively, by:
[tex]\mu = p = 0.4[/tex][tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.4(0.6)}{743}} = 0.018[/tex]The probability that the proportion of Grammy award winners will differ from the singers proportion by less than 3% is the p-value of Z when X = 0.43 subtracted by the p-value of Z when X = 0.37, hence:
X = 0.43:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.43 - 0.4}{0.018}[/tex]
Z = 1.67
Z = 1.67 has a p-value of 0.9525.
X = 0.37:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.37 - 0.4}{0.018}[/tex]
Z = -1.67
Z = -1.67 has a p-value of 0.0475.
0.9525 - 0.0475 = 0.905.
0.905 = 90.5% probability that the proportion of Grammy award winners will differ from the singers proportion by less than 3%.
