How do we find the area of a strange shape? Has six end points so it can become 4 triangles.

Sati [7]

In order to find the area for a strange shape, you divide it up into simpler figures. In this case, you already know that it can be divided into 4 triangles, so find the area of each triangle and add them up. Hope this helped!

Divide the sum of -13/5 and 12/7 by the product of -31/7 and -1/2

andriy [413]

Let's compute the two factors separately: as for "the sum of -13/5 and 12/7", we have to rewrite the two fractions so that they have the same denominator. Since the least common multiple of 5 and 7 is 35, we will change both fractions so that they have denominator 35:

$\frac{-13}{5} = \frac{-13}{5}\frac{7}{7} = \frac{-91}{35} \qquad \qquad \frac{12}{7} = \frac{12}{7}\frac{5}{5} = \frac{60}{35}$

So now we can sum them:

$\frac{-13}{5}+\frac{12}{7} = \frac{-91}{35}+\frac{60}{35} = \frac{-91+60}{35} = \frac{-31}{35}$

Multiplication is easier, since you just have to multiply numerators and denominators with each others:

$\frac{-31}{7} \frac{-1}{2} = \frac{-31 \cdot (-1)}{7\cdot 2} = \frac{31}{14}$

Finally, we must divide the two fractions. Dividing by a fraction is the same this as multiplying by the inverse of that fraction, i.e. we have to switch numerator and denominator:

$\frac{-31}{35} \div \frac{31}{14} = \frac{-31}{35} \cdot \frac{14}{31} = -\frac{2}{5}$

A local Honda dealership collects data on customers. Here is data from 311 customers who purchased a Honda Civic. Hybrid Honda C

Kobotan [32]

Answer:

Correct option is: Women are less likely to purchase a Honda Civic with a standard engine than men.

Step-by-step explanation:

Denote the variable as follows:

HHC = Hybrid Honda civic

SHC = Standard-engine Honda Civic

M = male

F = female

The data provided is:

HHC SHC Total

M 77 117 194

F 34 83 117

Total 111 200 311

Compute the probability distribution as follows:

$P (M\cap HHC)=\frac{77}{311}=0.2476$

$P(M\cap SHC)=\frac{117}{311}= 0.3762$

$P(F\cap HHC)=\frac{34}{311}= 0.1093$

$P(F\cap SHC)=\frac{83}{311}= 0.2669$

$P(M) =\frac{194}{311}= 0.6238$

$P(F)=\frac{117}{311} =0.3762$

$P(HHC)=\frac{111}{311}= 0.3569$

$P(SHC)=\frac{200}{311}= 0.6431$

The probability table is:

HHC SHC Total

M 0.2476 0.3762 0.6238

F 0.1093 0.2669 0.3762

Total 0.3569 0.6431 1.0000

Consider the probability distribution above.

The proportion of women purchasing a standard engine Honda civic is less then that for men.

Thus, the correct option is: Women are less likely to purchase a Honda Civic with a standard engine than men.

4 1/6 + (-2 5/6)= kjoijoijoiojijjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj

Bogdan [553]

Answer:

I don’t know about the last part but what I do know id the answer to the equation.

Answer: 1 1/3

Step-by-step explanation:

1. Remove the paranthesis

Removing the paranthesis will make it much easier to solve the equation.

We now have 4 1/6 + -2 5/6.

2. Rearrange the equation

We can’t have two symbols next to each other. We need to cross out one symbol so we can have only one. + and - = -. So let’s keep the "-" symbol.

We now have 4 1/6 - 2 5/6.

3. Solve the remaining equation

Now that we have a proper equation which we can solve, let’s do it.

We should then end up with 1 1/3.

Answer: 1 1/3
