Answer:
h = -5
Step-by-step explanation:
The two terms can be combined to simplify the equation to ...
100 = -20h
-5 = h . . . . . . . divide by -20
The equation is true when h = -5.

<em>Check</em>
-25(-5) +(-5)(5) = 125 -25 = 100 . . . as required
1 square yard = 36*36 = 1296 sq ins
So 120 square inches = 120 / 1296 = 0.0926 square yards

The null hypothesis is
The alternative hypothesis is
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.18
The sample size is n = 1240 airplane
The number of airplane is k = 310
Generally the sample proportion is
=>
=>
The null hypothesis is
The alternative hypothesis is
Answer:
2(1.25)+1.99+x≤5
Step-by-step explanation:
Because it says "at most $5" that means it would be either 2(1.25+1.99)−x≤5
or 2(1.25)+1.99+x≤5, which narrows it down to two. The reason it is the second option is because she is only buying two cards that cost $1.25, hence this part of the equation: <u>2(1.25)</u> +1.99+x≤5.
