Answer:

Yes she 1280 megabytes of additional 4% data and requires 1000 megabytes to upload 200 photos

Step-by-step explanation:

Given:

Data Plan for Shawn's Phone = 32000 megabytes.

She want to increase the data by 4% = $\frac{4}{32000}\times 100$ = 1280 megabytes

Each Photo uses 5 megabytes so 200 additional Photo will require = $5\times200= 1000\ megabytes$

She has 1280 megabytes of additional data and requires 1000 megabytes to upload 200 photos, so she have enough memory to do so.

Triangle J K L is shown. Angle J K L is a right angle. An altitude is drawn from point K to point M on side L J to form a right

KiRa [710]

Answer:

$3\sqrt{5}\ units$

Step-by-step explanation:

<u>Theorem 1:</u> The height of right triangle drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of the altitude is the geometric mean of these two segments. Hence,

$KM^2=ML\cdot MJ\\ \\6^2=ML\cdot 3\\ \\3ML=36\\ \\ML=12\ units$

<u>Theorem 2:</u> In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of each leg of the right triangle is the geometric mean of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.

Thus,

$KJ^2=MJ\cdot ML\\ \\KJ^2=3\cdot (3+12)\\ \\KJ^2=3\cdot 15\\ \\KJ^2=45\\ \\KJ=\sqrt{45}=3\sqrt{5}\ units$

Answer:

The correct option is D.) Causation cannot be determined from an observational study.

Step-by-step explanation:

The conclusion is not correct because

D.) Causation cannot be determined from an observational study.

Causation determined from an observational study is speculative and cannot be confirmed without data from a real experiment.

Fatima conducted an experiment where she asked people to estimate the temperature of glasses of water. She recorded how far the

LUCKY_DIMON [66]

Answer:

0.75°C

Step-by-step explanation:

Person A Person B Person C

-3 4 8

-1 -4 -2

0 2 5

2 -3 1

To get Fatima mean value, we have to add all the given values together

= - 3 + 4 + 8 - 1 - 4 - 2 + 0 + 2 + 5 + 2 - 3 + 1

= 9

Estimate is 9 deg above Actual Temperature in 12 readings

The formula for our Mean Value will be, the added values divided by actual temperatures

Added values = 9

Actual temperature = 12

Mean value = 9 ÷ 12 = 0.75°C above actual Temperature

Write an exponential function in the form y<br> and (3,72).<br> ab" that goes through points (0,9)

Vikentia [17]

Answer:

$y=9 ( {2}^{x} )$

Step-by-step explanation:

Let the exponential function be

$y = a {b}^{x}$

We substitute (0,9) to get:

$9 = a {b}^{0}$

$9 = a(1)$

$a = 9$

The equation now becomes:

$y = 9 {b}^{x}$

We substitute (3,72) to get:

$72 =9 {b}^{3}$

$8={b}^{3} \\ {2}^{3} = {b}^{3}$

$b = 2$

The equation is therefore

$y=9 ( {2}^{x} )$
