If f(x) = −2 + 8, what is f(−1.8)?<br><br> 4<br> 6<br> 10<br> 12
zysi [14]
I think that you typed wrongly. That has to be f(x)= -2x+8
If f(x)= -2x+8, we can solve that problem.
We replace x= -1.8 in that expression, that means: f(-1.8)= -2x(-1.8)+8= 3.6+8=11.6

But if the formula of f(x)=-2+8, that means f(x) has a stable value and that value is -2+8=6.
So for all x we always have f(x)=f(-1.8)=6

A pet store owner, Byron, needs to determine how much food he needs to feed the animals. Byron knows that he needs to order the
Brums [2.3K]

Answer:

He needs to buy 120 packages of dod food.

Step-by-step explanation:

b - bird food

h - hamster food

d - dog food

c - cat food

b + h + d + c = 600

b = h (bird food is the <em>same</em> as hamster food)

b = 4 d (bird food is <em>4 times</em> dod food)

c = d/2 (cat food is <em>half</em> dog food)

Total of packages ordered.

b + b + d + c = 600

4d + 4d + d + d/2 = 600

4 d + 4 d + d + d = 600. 2

10 d = 1.200

d= 120 .........the amount of dog food packages.

Light travels about 180 million kilometers in 10 minutes. How far does it travel in one minute? How far does it travel in one se
astraxan [27]

Answer:

18 million kilometers in one min. and 0.3 million kilometers in one second

Step-by-step explanation:

so the one min. is easy because all you have to do is take 180 and divide it by 10 and you get 18 million kilometers in one min. and then you would take 18 and divide it by 60 and you would get 0.3 million kilometers in one second

Suppose that the IQs of university​ A's students can be described by a normal model with mean 140 and standard deviation 8 poi
AnnZ [28]

Answer:

0.0266, 0.9997,0.7856

Step-by-step explanation:

Given that the IQs of university​ A's students can be described by a normal model with mean 140 and standard deviation 8 points. Also suppose that IQs of students from university B can be described by a normal model with mean 120 and standard deviation 11. Let x be the score by A students and Y the score of B.

A)P(X>135) = \\P(Z>0.625)\\=0.0266

B) Since X and Y are independent we have

X-Y is Normal with mean = 140-120 =20 and Var (x-y)=Var(x)+Var(y) = 19

P(X-Y)>5\\\\=1-0.00029\\=0.9997

C) For a group of 3, average has std deviation = \frac{11}{\sqrt{3} } \\=6.351

P(\bar y >115)\\= P(z>\frac{-5}{6.351} \\=0.7856
