Answer:

You already have the equations ready so I will just explain

Step-by-step explanation:

The first equation: place a point on the y-axis on -5. then proceed to place points by going down 2 and right 1 or by going up 2 and left 1. that will make your first line.

second equation: on the y-axis place a point on -1 then proceed to go up 1 right 1 or down 1 left 1. that makes your second line

How are a desert and a tundra similar?

Hatshy [7]

Answer:

D is right option

Step-by-step explanation:

Similarities:

Both the biomes experience less precipitation due to this they have a less diversity of flora and fauna as compared to other biomes like savanna, grasslands, chaparral etc. Let us see how they differ from each other!

Low rain fall _ annual rainfal of lessthan 20cm in deserts, 15-20cm in tundra

Minimal life_ only small shurbs can survive in both kind of environments

Poor drainage.. In deserts, though sandy soil may seem much porous, these are most flood prone areas of world. The tundra is characterised by permafrost soils ie, under the thin layer of soil, a thick ice sheet is present and hence is no seepage.

High range of temperatures: In tundra, the maximum temperatures are recorded in summer (abt 10^C) and minimum during winter(-20 to -30^C). While, in desert too, the temperature range is high but diurnally ie, nights are too cold and day time is scorching.

The coordinate plane below represents a city. Points A through F are schools in the city.

astra-53 [7]

Part A:
a system of inequalities that only contain points D and E in the overlapping shaded regions is
5y + 2x > 12
2y - x < 12

Part B:
To verify that points D and E are solutions to the system of inequalities, we plug in the coordinate points of points D and E into the system of ineaqualities.

Part C:
To identify the schools that Timothy is allowed to attend we plug in the coordinate values of the points to see which satisfies the inequality y < 3x - 3. Thus Timothy is allowed to attend schools C and F.

Please help What is the value of this expression when a = 7 and b = -4? |2a| - b/ 3

belka [17]

Answer:

46/3

Step-by-step explanation:

|2a| - b/3

Plug in the values and evaluate.

|2(7)| - (-4)/3

|14| + 4/3

Apply | a | = a

14 + 4/3

42/3 + 4/3

= 46/3

Suppose the age that children learn to walk is normally distributed with mean 12 months and standard deviation 2.5 month. 34 ran

Liono4ka [1.6K]

Answer:

Step-by-step explanation:

a.) it's just mean, variance

so here it's just 12,6.25

b.) For the x bar thing just divide the variance by the number of people (mean stay the same)

the variance is then (2.5²/34)= .1838

which makes it (12,.1838)

c.) here we don't use x bar (and so it's normal (12,2.5²))

p(11.6) = (11.6-12)/(2.5)= -.16 = .4364

p(12.4)= (12.4-12)/2.5 = .16= .5636

.5636-.4364= .1272

d.) here we use x bar because it's asking for an average so it's normal (12, .1838)

same deal

p(11.6)=(11.6-12)/√.1838= -.93295= .1762

p(12.4)= (12.4-12)/√.1838= .93295= .8238

.8238-.1762= .6476

d.) no because they're probably IID

f.) It's average so here we use x bar

q1 is just the 25th percentile

the 25th percentile is -.6745

-.6745=(x-12)/(√.1838)= 11.711

q3 is the 75th percentile

.6745=(x-12)/√.1838

x=12.289

The interquartile range is just the difference between the two

12.289-11.711= .5784

Help Me Plz!!!!!! THX!!!!!!!!!!

Sauron [17]

$\sqrt{5}$ is irrational

A rational number can be expressed in the form

$\frac{a}{b}$ where a, b ∈ Z ( integers )

$\frac{-9}{5}$ is in this form → rational

$\sqrt{5}$ cannot be expressed in this form → irrational

$\frac{7}{3}$ is in this form → rational

$\sqrt{9}$ = ± 3 and $\frac{3}{1}$ , - $\frac{3}{1}$ → rational
