"-the time people spend at work and the number of friends they have"
would be "causation"; because the more/less time someone spends at work is implied to be the *cause* of their number of friends.
"-the length of a person's hair and his or her math skills"
would be "no relationship" seeing as there's nothing that relates these two variables that could have an affect on the outcome of one or the other.
<span>"-a student's test scores in math and physics" would be "correlation" because the two subjects are similar enough that any outcome in one could very well be similarly related to the outcome in the other. </span>
Rules for rounding: If a number is less than 5, round down. If it is 5 or bigger, round up. Tenths is the one just to the right of the decimal. Since the hundredths is 5, we round up. The answer is 15.3

Answer: she will make $232.05 in 4 weeks.
Step-by-step explanation:
Since her profit is increasing by 10% each week, then the rate at which it is increasing is in geometric progression. The common ratio, r would be 110/100 = 1.1
We would apply the formula for determining the sum of n terms of a geometric progression which is expressed as
Sn = a(r^n - 1)/(r - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms(number of weeks)
From the information given,
a = 50
r = 1.1
n = 4 weeks
Therefore,
S4 = 50(1.1^4 - 1)/(1.1 - 1)
S4 = 50(1.1^4 - 1)/0.1
S4 = $232.05
Answer:
95.7
Step-by-step explanation:
\sin C = \frac{\text{opposite}}{\text{hypotenuse}}=\frac{95}{x}
sinC=
hypotenuse
opposite
=
x
95
\sin 83=\frac{95}{x}
sin83=
x
95
x\sin 83=95
xsin83=95
Cross multiply.
\frac{x\sin 83}{\sin 83}=\frac{95}{\sin 83}
sin83
xsin83
=
sin83
95
Divide each side by sin 83.
x=\frac{95}{\sin 83}=95.7134\approx 95.7\text{ feet}
x=
sin83
95
=95.7134≈95.7 feet
Type into calculator and roundto the nearest tenth of a foot.
