6 0

Given that Mandy Cart Contains :

5.1 pounds of Apples that cost $0.79 a Pound

From the above statement we can say that :

One Pound of Apples cost is 0.79 Dollar

5.1 Pounds of Apples cost = 5.1 × Cost of One Pound of Apples

5.1 Pounds of Apples cost = (5.1 × 0.79) Dollar = 4.029 Dollar

So the Cost of Apples Mandy Put in her Cart is 4.029 Dollar

Find a polynomial with a degree of 3 and zeros -3,3,5
Aliun [14]

Answer:

f(x) = x³ - 5x² - 9x + 45

Step-by-step explanation:

Given x = a, x = b are the zeros of a polynomial, then

(x - a), (x - b) are the factors and f(x) is the product of the factors.

Here the zeros are x = - 3, x = 3 and x = 5, thus

(x + 3), (x - 3) and (x - 5) are the factors and

f(x) = (x + 3)(x - 3)(x - 5) ← expand the first pair of factors using FOIL

     = (x² - 9)(x - 5) ← distribute

    = x³ - 5x² - 9x + 45

If the sides of a triangle are in the ratio 3:4:5, prove that it is<br>right-angled triangle​
lyudmila [28]

Answer:

hope this helps

Step-by-step explanation:

Let a , b , c are three sides of a triangle

a : b : c = 3 : 4 : 5

a = 3x ,

b = 4x ,

c = 5x

a² = 9x²

b² = 16x²,

c² = 25x².

c² = a² + b²

by the pythagorean theorem,

a , b , c forms a right angled Triangle.

You scored an 85 on a test. This corresponds to a z-score of 1.80. What percentage of the scores are better than yours?
Scrat [10]

At a z-score of 1.80, the percentage of the scores that are better than yours is equal to 3.59%.

<h3>What is a z-score?</h3>

In Mathematics, a z-score is sometimes referred to as a z-value or standard score and it can be defined as a measure of the distance between a raw score and the mean, when standard deviation units are used.

<h3>How to determine the percentage?</h3>

Mathematically, the z-score of a given sample score in a normal distribution can be calculated by using this formula:

Z-score = (x - μ)/σ

Where:

  • x represents the sample score.
  • σ represents the standard deviation.
  • μ represents the mean score.

Since a score of 85 on a test corresponds to a z-score of 1.80, the percentage of the scores that are better than yours is given by:

P(x > 85) = P(z > 1.80)

P(z > 1.80) = 0.0359

P(z > 1.80) = 3.59%.
