$\frac{5}{7} \: - \: \frac{3}{2}$

First, we find the <u>lowest common denominator</u> which is "14", we put it in the common numerator.

$\frac{10 \: - \: 21}{14}$

We subtract the numbers.

$\boxed{ \bold{- \frac{11}{14} }}$

P(A) = 0.12
$P(A\cap C)=0.05$
$P(A\cup C)=0.17=P(A)+P(C)-P(A\cap C)$
$0.17=0.12+P(C)-0.05$
$P(C)=0.17-0.12+0.05=0.10$

40% of students on a field trip love the museum. If there are 20 students on the field trip, how many love the museum??

MariettaO [177]

Since there are 20 students on the field trip. Then 20 is the 100% total. Thus, to find how many people love the museum, we can simply multiply the total number of people by the percentage of interest, namely 40%

20*0.4 = 8
So, 8 people love the museum.

Please help me with 8, 9, and 10 thanks! Show work too

Harrizon [31]

In 8, 9, 10, all the triangles are similar, meaning corresponding sides have the same ratio.

8. hypotenuse / (short side) = 25/x = x/9
x² = 25*9 = 5²×3²
x = √(5²×3²) = 5*3 = 15

9. (long side) / (short side) = x/7 = 9/x
x² = 7*9
x = √(9*7) = 3√7

10. (short side) / (long side) = x/48 = 48/64
x = 48²/64 = 36

First, the best advice I can give you is to go to sleep. You pretty much know what you know, and being well-rested will help you think clearly, recall details, and avoid careless mistakes.

1)
$=(5 \times 10^3)+(2 \times 10^2)=(50 \times 10^2)+(2 \times 10^2)\\=10^2(50+2)=52 \times 100 = 5200 = 5.2 \times 10^3$

2)

$=(5 \times 10^2) \times (5 \times 10^3)=5^2 \times 10^5 \\= 25 \times 100,000 = 2,500,000 = 2.5 \times 10^6$

3) Yes, dilating with a scale factor that is less than 1 (and greater than 0) corresponds to a decrease.

4) Yes, dilating with a scale factor greater than 1 corresponds to an increase.

5) To find the slope of a scatter plot, you need to make a line of best fit, that is, the line that passes through as many points as possible and has about as many points above it as below it. Then, find two of those points that the line passes through and calculate the slope between those points. For two points $(x_1,y_1)$ and $(x_2,y_2)$ , the slope is
$m= \dfrac{y_2-y_1}{x_2-x_1}$ .

This is an estimate. To find a better approximation, you can use the least-square method, but I think that probably involves higher-level math that you don't need. If you think you do need to solve it this way, just comment here and I'll explain it. Note that you can also calculate it using Microsoft Excel or a regression plot on a graphing calculator.
