Write the if/else statement as the conditional expression that performs the same option result = x < y ? x * 5 : a b;

Semenov [28]

The conditional statement is

if x < y:

result = x * 5

<h3>How to write the if/else statement as the conditional expression that performs the same option?</h3>

The statement is given as:

result = x < y ? x * 5

The above means that,

the variable result is assigned x * 5 if x < y

So, the conditional statement is

if x < y:

result = x * 5

The mean incubation time of fertilized eggs is 19 days. Suppose the incubation times are approximately normally distributed with

pochemuha

Answer:

a)17.92

b) 16.83 .... 21.17

Step-by-step explanation:

ρ→ z

0.14 = -1.080319341

-1.080 = (x - 19)/1 = 17.92

~~~~~~~~~~~~~~~~~~

3% / 2 = 1.5%

1.5% - 98.5%

ρ→ z

0.015 = -2.170090378 .... -2.17 = (x-19) =16.83

0.985 = 2.170090378 .... 2.17 = (x-19) =21.17

Elizabeth wants to use a sheet of fiberboard 27 inches long to create a skateboard ramp with a 17^{\circ}

erma4kov [3.2K]

The height of the ramp above the ground from its highest end is 7.9 inches.

<h3>What is height?</h3>

Height is the vertical distance between two points.

To calculate the height of the ramp above the ground, we use the formula below.

Formula:

h = Lsin∅............. Equation 1

Where:

h = Height of the ramp above the ground
L = Length of the fiberboard
∅ = Angle of elevation from the ground

From the question,

Given:

L = 27 inches
∅ = 17°

Substitute these values into equation 1

h = 27×sin17°
h = 7.89
h ≈ 7.9 inches

Hence, the height of the ramp above the ground is 7.9 inches.

What is 11 1/2 + 10 11/16=

ahrayia [7]

Hey!

To solve this equation, we must first convert the mixed numbers into improper fractions. To do that we'll multiply the denominator by the whole number and add the total to the numerator.

<em>Original Equation :</em>

$11\frac{1}{2} + 10\frac{11}{16} = ?$

<em>New Equation {Converted Mixed Numbers Into Improper Fractions} :</em>

$\frac{23}{2} + \frac{171}{16} = ?$

Now that we've successfully changed our equation, we'll move onto the next step. Next we'll have change the fractions one more time so that the denominators are the same. To do that we'll multiply two by eight to get sixteen. We'll also be multiplying the top portion of the fraction by eight, because whatever you do to the bottom must also be done to the top; And vise versa.

<em>Fraction Conversion :</em>

$\frac{23*8}{2*8} = \frac{184}{16}$

So, now that we have our new fraction we can go ahead and plug that into our equation so we can start adding. Remember, we don't add the denominators, just the numerators.

<em>Old Equation :</em>

$\frac{23}{2} + \frac{171}{16} = ?$

<em>New Equation {Input New Fraction With Common Denominator} :</em>

$\frac{184}{16} +\frac{171}{16} = ?$

<em>Solution {New Equation Solved} :</em>

$\frac{355}{16}$

Now I'm not exactly sure how your instructor will accept your answer, but most prefer the final answer to be in the simplest form. In other words, they don't want it in the form of an improper fraction. They'd most likely rather have it as a mixed number.

<em>New Solution {Converted to a Mixed Number} :</em>

$22\frac{3}{16}$

Since the fraction cannot be simplified anymore, this should be our final answer.

<em>So, this means that the answer to the equation is </em> $22\frac{3}{16}$ .

Hope this helps!
