Answer:

Step-by-step explanation:

12/24 reduces to 1/2, whereas 3/4 does not reduce. This pair of ratios does not form a proportion.

If both ratios reduced to the same common value, that would represent a proportion.

garri49 [273]

Answer:

Graph D > Graph A > Graph C > Graph B

Step-by-step explanation:

The closer the data points are to each other along the line of best fit, the greater the value of their correlation coefficient, and vice versa.

Therefore, the graphs can be arranged in descending other (from the highest to the lowest) based on the values of their correlation coefficients as follows:

Graph D > Graph A > Graph C > Graph B

Find the surface area of each figure round your answers to the nearest hundredth if necessary
Wewaii [24]

Answer: 410 square km

Step-by-step explanation:

The area of each of the triangles with their base on the 10 km side is A=\frac{1}{2}(10)(13.4), so their combined area is (10)(13.4)=134.

The area of each of the triangles with their base on the 12 km side is \frac{1}{2}(12)(13), so their combined area is (12)(13)=156.

The area of the bottom rectangular face is 10(12)=120.

So, the total surface area is 120+156+134=\boxed{410 \text{ km}^{2}}

olya-2409 [2.1K]

Answer:

x = \{13,14\}

Step-by-step explanation:

Given

x + 2x + 6 < 50

Required

True values of x

We have:

x + 2x + 6 < 50\\

3x + 6 < 50

Collect like terms

3x < 50-6

3x < 44

Divide both sides by 3

x < 44/3

x < 14.67

This means that x has a value lesser than 14.67.

Hence, the valid values are:

x = \{13,14\}
