show that the area of a square A inscribed in a circle with radius r is A=2r square​

Answer:

−49  / 8

decimal form- -6.125

Step-by-step explanation:

140−  167  / 8  (7)

=

140−  1169  / 8

=

−49  / 8

Step-by-step explanation:

Let's start by simplifying our light terms.

[tex]q = \frac{33 \times 10 {}^{9} }{11 \times 10 {}^{7} } [/tex]

33 is divisible by 11 so i can simplify up and down by 11.

[tex]q = \frac{3 \times 10 {}^{9} }{1 \times 10 {}^{7} } [/tex]

Now i have 10^9 in the numerator and 10^7 in the denominator. I can remove 10^7 from up and down to get;

[tex]q = \frac{3 \times 10 {}^{9 - 7} }{1 \times 10 {}^{7 - 7} } = \frac{3 \times 10 {}^{2} }{1 \times 10 {}^{0} } = \frac{3 \times 10 {}^{2} }{1 \times 1} [/tex]

[tex]q = 3 \times 10 {}^{2} [/tex]

And that is your scientific notation.

Answer: 300

Step-by-step explanation: 25 times 12 = 300. 20 times 12 = 240. 5 times 12 = 60. 60 + 240 = 300

Answer:

300

Step-by-step explanation:

25 times 12 = 300. 20 times 12 = 240. 5 times 12 = 60. 60 + 240 = 300

Answer:

The answer would be A) (-69, 15)

Solution:

Finding 1st and 2nd

m = (y2 - y1)/(x2 - x1)

m = (15 - 3 )/(6 - 3)

m = 12/3

y = 4x + b

3 = 3(3)+b

3=9+b

-9 -9

-6=b

Finding 3rd

repeat the above process for 1 and 2, so now use 2 and 3 in the equation.

m = -9/3

m=-3

y=-3x+b

15=-3(6)+b

b=-3

Step 2

Answer:

c=11

Step-by-step explanation:

We have two points ( 6,5) and (7,c) and a slope of 6

The slope formula is

m = ( y2-y1)/(x2-x1)

6 = (c-5)/(7-6)

6 = (c-5)/1

6 = c-5

Add 5 to each side

6+5 = c-5+5

11 =c

Space inside tent is 60m³

Step-by-step explanation:

Given length 6m, width 4m is rectangular base and height of tent 5m

Space = Volume of Pyramid = ⅓ × area of base × height

⅓ × 6 × 4 × 5 = 60m³

PLEASE MARK ME AS BRAINLIEST AND HAVE A NICE DAY :)

Answer:

Please Brainliest

2/13

Step-by-step explanation:

So firstly, know that there are 13 cards in the deck (3 + 6 + 4).

Therefore, the probability of drawing a green is 4/13.

After you draw the green card, there will be 12 cards left. Therefore, the probability of drawing a purple card next is 6/12.

To find compound probability, multiply the probabilities of the two separate events happening together:

4/13 * 6/12

= 2/13

The 99% confidence interval for the population mean will be x± [tex]\frac{2.58 s}{\sqrt{n} }[/tex].

A confidence interval is a set of calculations for an unrecognized parameter that is specified as a range with a lower and upper bound.

If we take an n-sample from a normal population and wish to estimate the population mean, the confidence interval for the mean is:

[tex]\bar x[/tex]±[tex]Z_\frac{\alpha }{2} \times \frac{s}{\sqrt{n} }[/tex]

The level of significance is found by;

[tex]\rm \alpha =1- \ condifidence\ level \\\\\ \rm \alpha =1- 0.99 \\\\\ \rm \alpha = 0.001[/tex]

The value of z is

[tex]\rm Z_{\frac{\alpha}{2}} = \rm Z_{\frac{0.01}{2}} = Z_{0.005}=2.58[/tex]

Hence the 99% confidence interval for the population mean will be x± [tex]\frac{2.58 s}{\sqrt{n} }[/tex].

Step-by-step explanation:

The answer above is correct.

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

so let's get two points from each table to get their slope or rate

Step-by-step explanation:

this was the correct answer as shown on the quiz. the choices were changed

Answer:

Choice: (3) -12 -(-7)

Step-by-step explanation:

The distance between two points is by definition a positive number. If we wanted to know the distance between points 5 and 8, we should use the absolute value of the difference:

d=|5-8|=8-5=3

The same applies to negative points like -2 and -7:

d=|-2+7|=|2-7|=7-2=5

The only choice that does not result in a positive distance is (3) because

-12-(-7)=-12+7=-5

Thus this is not a distance between two points on a number line.

Choice: (3) -12 -(-7)
