It is irrational because it is a decimal that doesn't terminate or repeat! :)

Change general form of hyperbola into standard: -x^2 + y^2 -16x + 14y - 251 = 0

topjm [15]

Answer:

(y+7)²/364 - (x+8)²/364 = 1

Step-by-step explanation:

This is the standard form of a vertical hyperbola (y-k)²/a² - (x-h)²/b² = 1

so, (y²+14y+?) - (x²+16x+?) = 251

(y²+14+49)-49 - (x²+16x+64)-64 = 251

(y+7)² - (x+8)² = 251 + 49 + 64

(y+7)² - (x+8)² = 364

(y+7)²/364 - (x+8)²/364 = 1

The following table shows the number of hours some teachers in two schools expect students to spend on homework each week: Schoo

Lerok [7]

Answer:

For school A: Minimum=6, Q₁=6.5, Median= 14, Q₃=16, Maximum=17, IQR=9.5

For school B: Minimum=5, Q₁=8, Median= 12, Q₃=15.5, Maximum=19, IQR=7.5

No, the box plots are not symmetric.

Step-by-step explanation:

Part A

The given data sets are

School A : 9,14,15,17,17,7,15,6,6

School B : 12,8,13,11,19,15,16,5,8

Arrange the data in ascending order.

School A : 6,6,7,9,14,15,15,17,17

School B : 5,8,8,11,12,13,15,16,19

Divide each data set in four equal parts.

School A : (6,6),(7,9),14,(15,15),(17,17)

School B : (5,8),(8,11),12,(13,15),(16,19)

For school A:

Minimum=6, Q₁=6.5, Median= 14, Q₃=16, Maximum=17

Interquartile range of the data is

$IQR=Q_3-Q_1=16-6.5=9.5$

For school B:

Minimum=5, Q₁=8, Median= 12, Q₃=15.5, Maximum=19

Interquartile range of the data is

$IQR=Q_3-Q_1=15.5-8=7.5$

Part B:

The box plots are not symmetric because the data values are different. Five number summary and IQR of both the data set are different.

Type a digit that makes this statement true. 425,9 0 is divisible by 3.

disa [49]

Answer:

1, 4, or 7

Step-by-step explanation:

For 425,9__0 to be divisible by three, the sum of the digits must be a multiple of three.

Using this knowledge, the numbers 1, 4, and 7 are all answers to this problem.

425, 910: 4 + 2 + 5 + 9 + 1 + 0 = 21

21 is divisible by 3.

Repeat this for 4 and 7.

Hope this helped!

Chloe collected 4 times as many bags of cans as her friend. If her friend collected 1/6 of a bag , how much did Chloe collect?

lana66690 [7]

Since Chloe collected 4 times as much as her friend, who collected 1/6 a bag, you will have to multiply 4 by 1/6 to find how much Chloe collected.

To multiply fractions, you multiply the numerators and multiply the denominators. Then you put the product you got from multiplying the numerators over the product you got from multiplying the denominators. Remember that 4 is the same as 4/1. Simplify the product if needed.:
$\frac{4}{1} \times \frac{1}{6} = \frac{4}{6} = \frac{2}{3}$

Chloe collected 2/3 of a bag.
