hello! im taking a flvs test right now and this question popped up so let me help.

zoe's question's data would vary because not everyone in her class could play video games for the exact same amount of time.

however this is not a statistical question because we do not know when the students are playing video game for example we wouldnt know if she wanted to know how much time a classmates spends playing video games each year, each month, each week, etc. so to make this a statistical question zoe would have to ask....  which student spends the most time a day on video games.

hope this helps ;D

Step-by-step explanation:

yes because it would give you numbers that you could then use to make some sort of chart to better understand your data

-7 = -1 + x/3, solve and explain with an algebraic property
k0ka [10]
-7 = -1 +  \frac{x}{3}

Multiply both sides by 3 :

-3*1 + 3* \frac{x}{3}  = -3*7

Refine:

x - 3 = -21

x = - 21 + 3

x = - 18

hope this helps!.

A privately owned lake contains two types of game fish, bass and trout. The owner provides two types of food, A and B, for these
Vinvika [58]

Answer:

133 fishes

Step-by-step explanation:

Units of food A = 400 units

Units of food B = 400 units

Fish Bass required 2 units of A and 4 units of B.

Fish Trout requires 5 units of A and 2 units of B.

i. For food A,

total units of food A required = 2 + 5

                                                 = 7 units

number of bass and trout that would consume food A = 2 x \frac{400}{7}

                                               = 114.3

number of bass and trout that would consume food A = 114

ii. For food B,

total units of food B required = 4 + 2

                                                = 6 units

number of bass and trout that would consume food B = 2 x \frac{400}{6}

                                                 = 133.3

number of bass and trout that would consume food B = 133

Thus, the maximum number of fish that the lake can support is 133.

1000 was invested at 5.5% interest, compounded annually. After sometime the amount had grown to 1550. How long was the money inv
scZoUnD [109]

compound interest equation for annually compounded

A=P(1+r)^t

A=final amount

P=principal

r=rate in decimal

t=time in years


given that

A=1550

P=1000

r=5.5%=0.055

find t


1550=1000(1+0.055)^t

divide both sides by 1000

1.55=1.055^t

take ln of both sides

ln(1.55)=ln(1.055^t)

use ln rule ln(a^b)=b(ln(a))

ln(1.55)=t(ln(1.055))

divide both sides by ln(1.055)

\frac{ln(1.55)}{ln(1.055)}=t

using a calculator, we get that t=8.18544 yrs

so about 8.2yrs
