Answer:

Yes,they are congruent.

Step-by-step explanation:

We are required to make two transformations and prove that they are congruent.

First Transformation:Now rotate the polygon FGHIJ by 90° about the axis parallel to x-axis and passinfg through the vertex I.You can observe that the sides are of same length AB=GF=2 units.

Second Transformation: Keeping the polygon ABCDE constant shift the centre of polygon FGHIJ to the centre of polygon ABCDE you will observe thta they exactly overlap on each other hence they are congruent with each other.

In a recent year, a sample of grade 8 Washington State public school students taking a mathematics assessment test had a mean sc

Daniel [21]

Answer:

The number is $N =1147$ students

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 281$

The standard deviation is $\sigma = 34.4$

The sample size is n = 2000

percentage of the would you expect to have a score between 250 and 305 is mathematically represented as

$P(250 < X < 305 ) = P(\frac{ 250 - 281}{34.4 } < \frac{X - \mu }{\sigma } < \frac{ 305 - 281}{34.4 } )$

Generally

$\frac{X - \mu }{\sigma } = Z (Standardized \ value \ of \ X )$

So

$P(250 < X < 305 ) = P(-0.9012< Z$

$P(250 < X < 305 ) = P(z_2 < 0.698 ) - P(z_1 < -0.9012)$

From the z table the value of $P( z_2 < 0.698) = 0.75741$

and $P(z_1 < -0.9012) = 0.18374$

$P(250 < X < 305 ) = 0.75741 - 0.18374$

$P(250 < X < 305 ) = 0.57$

The percentage is $P(250 < X < 305 ) = 57\%$

The number of students that will get this score is

$N = 2000 * 0.57$

$N =1147$

Pepper jackie purchased 3.5 pounds of jelly beans for 1.19 per pund. How much did she spend on jelly beans, to the nearest cent

Pani-rosa [81]

Answer:

416.5 cent Pepper jackie spend on jelly beans .

Step-by-step explanation:

As given

Pepper jackie purchased 3.5 pounds of jelly beans for $1.19 per pound.

Thus

$1.19 = 1 pound

Cost of 3.5 pounds of jelly beans = 1.19 × 3.5

= $4.165

Therefore the cost of 3.5 pounds of jelly beans is $4.165 .

As 1 dollar = 100 cent

$4.165 = 4.165 × 100

= 416.5 cent

Therefore 416.5 cent Pepper jackie spend on jelly beans .
