Mathematics
1 answer:
kvasek [131]2 years ago
3 0

Answer:Mapping Rule A mapping rule has the following form (x,y) → (x−7,y+5) and tells you that the x and y coordinates are translated to x−7 and y+5. Translation A translation is an example of a transformation that moves each point of a shape the same distance and in the same direction.

How many lengths of wire, each 3 3/4 inches. long can be cut from a 25-ft roll?
lianna [129]

Answer:

80 pieces of wire.

Step-by-step explanation:

It may not come out evenly. If there is a remainder, it won't matter. Just throw it away and go with the integer answer.

Change 3 3/4 to a decimal

3.75

Change the 25 foot roll to inches.

25 feet * 12 inches / foot  = 300 inches.

Now how many pieces of wire do we get.

1 piece of wire/3.75 inches = x pieces of wire / 300 inches

3.75 * x = 300

3.75 * x / 3.75 = 300 / 3.75

x = 80

The distances male long jumpers for State College jump are approximately normal with a mean of 263 inches and a standard deviati
Effectus [21]

Answer:

His jump was of 272.45 inches

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 263, \sigma = 14

75th percentile

X when Z has a pvalue of 0.75. So X when Z = 0.675

Z = \frac{X - \mu}{\sigma}

0.675 = \frac{X - 263}{14}

X - 263 = 14*0.675

X = 272.45

His jump was of 272.45 inches

Calculate the missing terms of the geometric sequence ...,3072, 7,2,7, 12,.... Select all that apply.
miskamm [114]

Answer:

The missing terms are 768, 192, 48.

Step-by-step explanation:

From the given geometric sequence

First term= a_1=3072

Fifth Term= a_5=12  

The general form of a geometric sequence is:

a_n=ar^(n-1)

here a_nis the nth term, a is the first term and r is the common ratio.

We will use the general form for term 5 to calculate the value of r.

So the general form for term 5 will be

a_5=3072* r^(5-1)

Putting the value of a_5

12=3072* r^4

r^4=  12/3072

r^4=  1/256

r^4=  1/[(4)^4]

Solving for r  

r=  1/4

Now  

a_2= ar^(2-1)

a_2=3072*r

a_2=3072*  1/4

a_2=768

a_3= ar^(3-1)

a_3=3072*r^2

a_3=3072*(1/4)^2

a_3=3072*  1/16

a_3=192

a_4= ar^(4-1)

a_4=3072*r^3

a_4=3072*(1/4)^3

a_4=3072*  1/64

a_4=48

alexdok [17]

Answer: 46 puzzles  

Step-by-step explanation:

There are 70 puzzles in total in the book.

Jackie has completed / of those puzzles. In whole numbers that is:

= 2 /5 * 70

= 28 puzzles

She then completes 18 more puzzles.

Total that she has completed is:

= 28 + 18

= 46 puzzles
