Answer:

(7,4)

Step-by-step explanation:

When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative. (7,8)

Afterwards, four units down means changing the y coordinate we have, thus making our (8) into (4.)

Hope this helps!

Answer:

Usual, because the result is within the range of the minimum and maximum usual values.

Step-by-step explanation:

When the z-scores is lower than -1.96 or higher than 1.96, they are considered as unusual and interesting and they are statistically significant outliers.

The Z score can be calculated by,

where,

X = raw score = 622.3

μ = mean = 674

σ = standard deviation = 26.6

Putting tall the values,

As , so the result is usual, because it lies within the range of the minimum and maximum usual values.

sergiy2304 [10]

Answer:

99 dandelions

Step-by-step explanation:

Given: ratio of dandelions to peonies in the garden was 11 to 4

Total number of peonies in the garden = 36

To find: Total number of dandelions in the garden

Solution:

A ratio indicates number of times one quantity contains another quantity.

$\frac{Number\,\,of\,\,dandelions }{Number\,\,of\,\,peonies} =\frac{11}{4}\\\\\frac{Number\,\,of\,\,dandelions}{36} =\frac{11}{4}\\ Number\,\,of\,\,dandelions=(\frac{11}{4}) (36)=99$

So,

99 dandelions were there in the garden.

(f+g) means add the expressions together. combine like terms.
$5 {x}^{2} + 3 {x}^{2} = 8 {x}^{2}$
$- 2x + x = - x$
there is no other constant term so the -4 stays as is.
