Answer:

Continuous

Step-by-step explanation:

Here we are asked to determine that the data given to us in form of rates of pizza and the toppings is discrete or the continuous.

The discrete data always come in integers where as the continuous data can come in decimals too. For example the number if student in a class is always a discrete data where as the weight of the students in a class is continuous data.

Here we can see that the cost of pizza and the toppings are in decimals. Hence here the data is continuous

svp [43]

Answer:

x = -7/40 , y = -11/20

Step-by-step explanation:

Solve the following system:

{12 x - 2 y = -1 | (equation 1)

4 x + 6 y = -4 | (equation 2)

Subtract 1/3 × (equation 1) from equation 2:

{12 x - 2 y = -1 | (equation 1)

0 x+(20 y)/3 = (-11)/3 | (equation 2)

Multiply equation 2 by 3:

{12 x - 2 y = -1 | (equation 1)

0 x+20 y = -11 | (equation 2)

Divide equation 2 by 20:

{12 x - 2 y = -1 | (equation 1)

0 x+y = (-11)/20 | (equation 2)

Add 2 × (equation 2) to equation 1:

{12 x+0 y = (-21)/10 | (equation 1)

0 x+y = -11/20 | (equation 2)

Divide equation 1 by 12:

{x+0 y = (-7)/40 | (equation 1)

0 x+y = -11/20 | (equation 2)

Collect results:

Answer:  {x = -7/40 , y = -11/20

siniylev [52]

Answer:

= 21.6216% decrease

Step-by-step explanation:

Calculate percentage change

from V1 = 29.6 to V2 = 23.2

(V2−V1)|V1|×100

=(23.2−29.6)|29.6|×100

=−6.429.6×100

=−0.216216×100

=−21.6216%change

=21.6216%decrease

Can someone please help me out<br> ASAP I WILL GIVE OUT BRAINLY
SashulF [63]

Answer:

x = 9

Perimeter = 74

Area = 342

Step-by-step explanation:

First, find x. to do so, set your formula up as

18 = 8x - 54

18 + 54 = 8x

72 = 8x

72/8 = x

9 = x

Now that you have x, find your missing side

2x + 1 = y, x

2 * 9 + = y

19 = y

Your perimeter is P = 2(l+W)

P = 2(18 * 19)

P = 74

Your area is A = wl

A = 19 * 18

A = 342

Softa [21]

Answer:

P(49.5

P(-1.192

P(-1.192

Step-by-step explanation:

We define X the random variable that represent the heights of a population for ten year old children, and for this case we know the distribution for X is given by:

X \sim N(55.7,5.2)  

Where \mu=55.7 and \sigma=5.2

We want to find this probability:

P(49.5

We can use the z score formula to solve this problem given by:

z=\frac{x-\mu}{\sigma}

Using this formula we have:

P(49.5

And we can find this probability with this difference

P(-1.192

We can use tables for the normal standard distribution, excel or a calculator and we got this

P(-1.192
