Answer:

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Step-by-step explanation:

The process by which plants use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

What is the simplest radical form of the expression? (x3y5)4/3

VikaD [51]

Rational exponents work as follows:

$a^{\frac{b}{c}}=\sqrt[c]{a^b}$

So, in your case, we have

$(x^3y^5)^{\frac{4}{3}} = \sqrt[3]{(x^3y^5)^4}=\sqrt[3]{x^{12}y^{20}}=\sqrt[3]{x^{12}y^{18}\cdot y^2}}=x^4y^6\sqrt[3]{y^2}$

Write the equation for the line of best fit

Vsevolod [243]

Given:

The given graph shows the scatter points.

We need to determine the equation for the line of best fit.

Slope of the equation:

From the figure, it is obvious that the slope of the line is $m=2.33$

Rounding off to the nearest tenth, we get;

$m=2.3$

Thus, the slope of the equation is $m=2.3$

Value of y - intercept:

From the figure, it is obvious that the y - intercept is $b=33.153$

Rounding off to the nearest tenth, we get;

$b=33.2$

Thus, the y - intercept of the equation is $b=33.2$

Equation of the line:

The equation of the line can be determined using the formula,

$y=mx+b$

Substituting $m=2.3$ and $b=33.2$ , we get;

$y=2.3x+33.2$

Thus, the equation for the line of best fit is $y=2.3x+33.2$

You took a random sample of 12 two-slice toasters and found the mean price was $61.12 and the standard deviation was $24.62. Con

Minchanka [31]

Answer:

Step-by-step explanation:

We want to determine a 95% confidence interval for the population mean for the prices of slice toasters.

Number of sample, n = 12

Mean, u = $61.12

Standard deviation, s = $24.62

For a confidence level of 95%, the corresponding z value is 1.96.

We will apply the formula

Confidence interval

= mean ± z ×standard deviation/√n

It becomes

61.12 ± 1.96 × 24.62/√12

= 61.12 ± 1.96 × 7.107

= 61.12 ± 13.93

The lower end of the confidence interval is 61.12 - 13.93 =47.19

The upper end of the confidence interval is 61.12 + 13.93 = 75.05
