If 1.) Gabby made a scale drawing of the Sam Houston statue in Huntsville, TX. The statue is actually 67 feet tall. Gabby's model used a scale of 1 inch = 20 feet. What was the length of her drawing?​

Answers

Answer:

3.35 inches

Step-by-step explanation:

Actual height of statue = 67 feets

Scale used : 1 inch = 20 feets

Let Length of drawing = x

1 inch = 20 feets

x inch = 67 feets

Cross multiply to obtain the length of the drawing in inches

20 * x = 67 * 1

20x = 67

x = 67 / 20

x = 3.35 inches

Hence, length of her drawing is 3. 35 inches

Maria wants to know if the number of words on a page in her earth science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.



Mean Median Mean Absolute Deviation
Earth science 48.9 41 9.2
Math 34.5 44 1.9
She claims that because the mean number of words on each page in the earth science book is greater than the mean number of words on each page in the math book, the earth science book has more words per page. Based on the data, is this a valid inference?

Answers

Answer:

No, because there is a lot of variability in the earth science book data.

Step-by-step explanation:

I just took the test and the explanation is that the earth book has more pages and more variability so that is why her answer is wrong.

Edge: Which equation has a focus at (–6, 12) and directrix of x = –12?

Answers

The solution is, b. x² = 12(y + 3) equation represents a parabola that has a focus of (0, 0) and a directrix of y = −6

What is parabola?

The parabola is a plane curve which is mirror symmetrical and is approximately U-shaped. It fits several superficial different mathematical descriptions.

here, we have,

If the focus is (0,0) and the  directrix  is y=-6, the equation will be found as follows:

Let (x,y) be any point on the parabola. Find the distance between (x,y) and the directrix, then find the distance between (x,y) and the focus. Equate these two distance equations and the simplified equation in x and y is equation of the parabola.

The distance between (x,y) and (0,0) is √(x²+y²)

The distance between (x,y) and the directrix, y=-6 is ly+6l

Equate the two distance expressions and square on both sides

√(x²+y²)=ly+6l

x²+y²=(y+6)²

simplifying and bringing terms together we get:

x²-12y-36=0

make x² the subject:

x²=12y+36

x²=12(y+3)

Hence, Answer :b. x² = 12(y + 3)

You pick a card at random. Without putting the first card back, you pick a second card at random.

What is the probability of picking a 5 and then picking an even number?

Answers

3/5 because since you took out an odd number, there is now 5 cards in total, and there are 3 even numbers.

Answer:

1/10 or 10%

Step-by-step explanation:

Probability = favorable outcome / total number of outcomes

p(5) = 1/6

5 numbers left and 3 of them are even.

p(even) = 3/5

So combined probability is:

p(5 and even) = 1/6*3/5 = 1/10

was there supposed to be a picture included.

Step-by-step explanation:

The price of a washing machine was decreased by 20% to £640.
What was the price before the decrease?

Answers

Answer:

£800

Step-by-step explanation:

Use the percentage formula: NV = m x OV

NV is New Value;

m is Multiplier;

and OV is Old Value.

£640 in the New value, so now we have to convert 20% to a multiplier and find out the Old value.

Make OV the subject of the formula: OV = NV / m

So 20% decrease would mean: 100 - 20 = 80 * 100 = 0.80

Divide 640 (NV) by 0.80 (m) and it will give you:

£800

And it would make sense that the OV is higher, and it matches the statement -> as the NV is the decrease.

Mercury is the closest planet to the sun at a distance of 36 million miles. The closest star to the sun is Proxima Centauri, which is 4.24 light years away. A light year is 5.9 x 10 to the 12th power. How many miles from the sun is Proxima Centauri?

Answers

Answer:

2.36 * 10^13 miles

Step-by-step explanation:

Given that :

Proxima centauri is at a distance of 4.24 light years away from the sun.

Distance in miles of Proxima centauri from the sun ;

1 light year = 5.9 * 10^12 miles

Number of light years from the sun * 5.9 * 10^12

= 4 * (5.9 * 10^12)

= 23.6 * 10^12 miles

= 2.36 * 10^13 miles
