Answer:

The correct option is 2.

Step-by-step explanation:

We have to find the value of P(0.6 ≤ z ≤ 2.12).

$P(0.6\leq z\leq 2.12)=P(z\leq 2.12)-P(z< 0.6)$

From the Cumulative Standardized Normal Distribution table,

$P(z\leq 2.12)=0.9830$

$P(z$

$P(0.6\leq z\leq 2.12)=0.9830-0.7257$

$P(0.6\leq z\leq 2.12)=0.2573$

$P(0.6\leq z\leq 2.12)\approx 0.26=26\%$

Therefore the correct option is 2.

The power 3 Superscript negative 3 equals StartFraction 1 Over 27 EndFraction . Which expression is equivalent to 3 Superscript

SpyIntel [72]

Answer:

Option a: \frac{m^{5} }{162n} is the equivalent expression.

Explanation:

The expression is \frac{(3m^{-2} n)^{-3}}{6mn^{-2} } where m\neq 0, n\neq 0

Let us simplify the expression, to determine which expression is equivalent from the four options.

Multiplying the powers, we get,

\frac{3^{-3}m^{6} n^{-3}}{6mn^{-2} }

Cancelling the like terms, we have,

\frac{3^{-3}m^{5} n^{-1}}{6 }

This equation can also be written as,

\frac{m^{5}}{3^{3}6 n^{1} }

Multiplying the terms in denominator, we have,

\frac{m^{5} }{162n}

Thus, the expression which is equivalent to \frac{(3m^{-2} n)^{-3}}{6mn^{-2} } is \frac{m^{5} }{162n}

Hence, Option a is the correct answer. 23

Marcus and Jeremy both evaluated the expression −52 + 3. Marcus said the answer was −22. Jeremy said the answer was 28. Who is c

Artyom0805 [142]

Answer:

Alright, the answer to the equation -52+3= -49

Step-by-step explanation:

I don't know how the heck Marcus and Jeremy got -22 and 28 but both are wrong. If there were a picture so I could see their work, I would be able to figure it out.

Anyways, The math is:

-52 + 3 which is pretty much 52-3 and then the answer has a negative sign.

-52 goes up 3 because technically the negative sign is down. Counting up 3 from 52 equals -49.

Complete the table of inputs and outputs for the given function g(x)=3-8x.

Andreas93 [3]

Answer:

The answers to your questions are given below.

Step-by-step explanation:

From the question given above,

g(x) = 3 – 8x

Thus, we can complete the table given in question above as follow:

1. Determination of x

g(x) = 0

x =?

g(x) = 3 – 8x

0 = 3 – 8x

Collect like terms

0 – 3 = – 8x

– 3 = – 8x

Divide both side by –8

x = – 3 / –8

x = 3/8

2. Determination of g(x)

x = 0

g(x) =.?

g(x) = 3 – 8x

g(x) = 3 – 8(0)

g(x) = 3 – 0

g(x) = 3

3. Determination of x

g(x) = – 5

x =?

g(x) = 3 – 8x

– 5 = 3 – 8x

Collect like terms

– 5 – 3 = – 8x

– 8 = – 8x

Divide both side by – 8

x = – 8 / – 8

x = 1

4. Determination of g(x)

x = 3

g(x) =.?

g(x) = 3 – 8x

g(x) = 3 – 8(3)

g(x) = 3 – 24

g(x) = – 21

Summary

x >>>>>>>>>>>>>>> g(x)

3/8 >>>>>>>>>>>>> 0

0 >>>>>>>>>>>>>>> 3

1 >>>>>>>>>>>>>>>> – 5

3 >>>>>>>>>>>>>>> – 21

Andy buys x cakes. Betty buys 4 times as many cakes as Andy. Colin buys 3 more cakes than Andy. Each cake costs 65p. The total c

Paladinen [302]

Answer:

Each cake cost £ 13.00

Step-by-step explanation:

We were given that, each cake costs $65p$ or £ $0.65$

Andy buys $x$ cakes.

Andy's cost is

£ $0.65x$

Betty buys 4 times as many cakes as Andy.

Betty's cost is

£ $0.65(4x)$

£ $2.60x$

Colin buys 3 more cakes than Andy

Colin's cost is

£ $0.65(x+3)$

The total cost of the cakes is £ $52.65$ .

This implies that,

$0.65x+0.65(x+3)+2.60x=52.65$

We expand to get,

$0.65x+0.65x+1.95+2.60x=52.65$

We group like terms to get,

$0.65x+0.65x+2.60x=52.65-1.95$

This gives us,

$0.65x+0.65x+2.60x=52.65-1.95$

This implies that,

$3.9x=50.7$

$x=\frac{50.7}{3.9}$

$x=13$

Therefore each cake cost £ 13.00

Burnem Inc. manufactures thumb drives and sells them to a distributor. Burnem's total cost and total revenue (in dollars) for x

AlladinOne [14]

Answer:

444 thumb drives

Step-by-step explanation:

Break even is the point at which the proceeds are equal to the costs i.e. when Total cost = Total revenue. So using the equations provided, the breakeven point for Burnem Inc. will be 4x + 4884 = 15x, where x is number of thumb drives. We solve for x to get the answer:

4x + 4884 = 15x

4884 = 15x - 4x

4884 = 11x

x = 4884/11

x = 444 thumb drives
