PLEASE HELP ILL MARK YOU BRAINLIEST A student is assessing the correlation between the number of hours a plant receives sunlight

Studentka2010 [4]

Glad you ask!!!

Part A: ok so... linear correlation between the number of hours of sunlight that a plant receives and the eight it grows. so its like the amount of sunlight.

Part B: The function that is the best fit is y=3x+4

Part C: The slope shows the plant and the intersection with the y axis

Hope this helps :)

krok68 [10]

Answer:

The answer is "(0.461 , 7.206)"

Step-by-step explanation:

In the given question some information is missing, that is data. so, the correct answer to this question can be defined as follows:

UnLogged:

$x_1=17.500\\s_1=3.529\\n_1=12$

Logged:

$x_2=13.667\\ s_2=4.500\\n_2=9\\$

formula of std error:

$\ std \ error =\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$

$=\sqrt{\frac{3.529^2}{12}+\frac{4.500^2}{9}}\\\\=\sqrt{\frac{3.529^2\times 3+4.500^2\times 4}{36}}\\\\=1.8133$

Point differential estimation = $x_1-x _2$

$= 17.500-13.667\\=3.833$

For 90 percent t= 1.860 Cl & 8 df

error of margin E = $t\times \ std \ error$

$= 1.860 \times 1.8133\\= 3.373$

Lower bound =mean difference -E=0.461

Upper bound = mean difference+ E=7.206

In the above 90% confidence interval were the population mean= (0.461 , 7.206)

What is the area of △STU rounded to the nearest tenth?

valentinak56 [21]

Answer:

38.7 units²

Step-by-step explanation:

4.6/SV = SV/8.1

SV² = 37.26

SV = 6.1

area = 1/2(8.1)(6.1) + 1/2(4.6)(6.1) = 38.7 units²

What is the approximate area of the circle shown below?

bekas [8.4K]

Answer:

A. 804 cm²

Step-by-step explanation:

Formula :

$\boxed{A = \pi r^2}$

A = 3.14 × 16²

A = 3.14 × (16 × 16)

A = 3.14 × 256

A = 803.84 cm²

A = <u>8</u><u>0</u><u>4</u><u> </u><u>cm²</u> (rounded)

So, the approximate area of the shown below is 804 cm² (A)
