30 POINTS - The tables below represent the profits earned by a merchandiser from four new consignments of t-shirts. Each consign

ment contained t-shirts of five different sizes. If we were to plot each of the t-shirt sizes and the profit earned on each new size, we would get a different graph for each consignment. Almost all the graphs showed some association between the two variables, except one consignment, which showed no association. Which of the following consignments shows no association?

The answer is the 2nd graph having a profit of 5, 15, 6, 18, and 10.
Graph 1, 3, and 4 showed a similar linear association, with the exception of graph 3 having a negative slope. In graph 2, however, the data is scattered which showed no association between the two variables.

Note: Refer to the attached pictures.

A Unites States naval submarine began at sea level. It submerged 140 ft and then traveled 40 miles. It dove down an additional 1
kodGreya [7K]

Answer: -231 ft

<u>Step-by-step explanation:</u>

The submarine started at sea level = 0

It submerged 140 ft = -140 ft

It traveled 40 miles horizontally so it is still at -140 ft

It dove down an additional 120 ft = -260 ft <em>(-140 + -120)</em>

It traveled 25 miles horizontally so it is still at -260 ft

It rose 29 ft = -231 ft <em>(-260 + 29)</em>

Note: submerged and dove are negative values and rose is positive

0 - 140 - 120 + 29 = -231

Answer:

number of terms=9

Step-by-step explanation:

t_{1}=6\\t_{5}=18\\\\t_{n}=t_{1}+(n-1)d\\18=6+(5-1)d\\18-6=4d\\4d=12\\d=12/4=3\\s_{n}=162\\s_{n}=\frac{n}{2}[2t_{1}+(n-1)d]\\162=\frac{n}{2}[2(6)+(n-1)3]\\162 \times 2=n(12+3n-3)\\324=n(3n+9)\\3n^2+9n-324=0\\n^2+3n-108=0\\n^2+12n-9n-108=0\\n(n+12)-9(n+12)=0\\(n+12)(n-9)=0\\n=-12,9\\n=-12 (rejected)

as number of terms can't be negative.

In a quadrilateral, three of the angles are obtuse. Which of the following could not be the angle measure of the fourth angle?
Luba_88 [7]
If an angle it is obtuse it is between 90 and 180.

Angles in a quadrilateral add up to 360.

Therefore 3 obtuse angles must add up to AT LEAST 273 and if you then added the 90 it would get you to 363 which is too large so it cant be 90 :)

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall. Sean's video game system measures 1 inch lon
Lady_Fox [76]

Answer:

Combined volume of the two game systems  =416 cubic inches

Step-by-step explanation:

Volume of a cuboid = length × breadth × height

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.

So,

Volume of Soham's video game system = 8 × 6 × 2 = 96 cubic inches

As Sean's video game system measures 1 inch longer on all sides,

the video game system measures 8+2=10 inches long, 6+2=8 inches wide, and 2+2=4 inches tall.

Volume of the video game system = 10 × 8 × 4 = 320 cubic inches.

Therefore,

Combined volume of the two game systems = 96+320=416 cubic inches
