Assume that x is a variable that has been declared as a double and been given a value. Write an expression to compute the quarti

Vladimir [108]

Answer:

$x^{\frac{1}{4}}$

Step-by-step explanation:

x is a variable which has been declared of type double.

Then square root of x can be expressed as $\sqrt{x}$

The quartic root of a number is the square root of its square root.

In other words, quartic root of x can be expressed as $\sqrt{\sqrt{x}}$

This can be expressed equivalently as $\sqrt{x^{\frac{1}{2}}}$

$={x^{\frac{1}{4}}}$

India can paint 3 1/5 walls in one day. How many walls can she paint in 5 1/2 days?

sladkih [1.3K]

Change the mixed numbers into fractions.

$3 \frac{1}{5}$
$3 * 5 = 15$
$15 + 1 = 16$
$3 \frac{1}{5} = \frac{16}{5}$

$5 \frac{1}{2}$
$5 * 2 = 10$
$10 + 1 = 11$
$5 \frac{1}{2} = \frac{11}{2}$

Multiply these fractions together:

$\frac{16}{5} * \frac{11}{2} = \frac{176}{10} 
$

Simplify the fraction.

$\frac{176}{10} / \frac{2}{2} = \frac{88}{5}$

$88 / 5 = 17 R3 = 17 \frac{3}{5}$

India can paint 17 and 3/5 walls in 5 and a half days.

A 95% confidence interval for the slope of the regression line relating the number of grams of carbohydrates and the number of k

horsena [70]

Answer: E. We are 95% confident that the true slope of the regression line relating grams of carbohydrates and kilocalories per 100-g sample of various raw foods is between 2.505 and 6.696.

Step-by-step explanation:

The interpretation of a 95% confidence interval: A person can be 95% confident that the true population parameter lies in it.

Given: A 95% confidence interval for the<em> slope of the regression </em>line relating the number of grams of carbohydrates and the number of kilocalories per 100-gram sample of various raw foods is given by (2.505,6.696).

Interpretation: We are 95% confident that the true slope of the regression line relating grams of carbohydrates and kilocalories per 100-g sample of various raw foods is between 2.505 and 6.696.

Correct option: E
