What is the additive inverse of ?

1 answer:

8 0

In mathematics, the additive inverse of a number a is the number that, when added to a yields zero. This operation is also known as the opposite (number), sign change, and negation. ... For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0 .

Complete the equation of the graphed linear function. Write the slope in decimal form.

erma4kov [3.2K]

Every straight line graph has an equation in the same form:

   y = (slope of the line) x + (y-intercept) .

-- The slope of the line is

   (how far it goes UP, going left to right between any 2 points)
divided by
   (how far it goes left to right between the same 2 points) .

The line on this graph has a slope of + 1/2 .

-- The y-intercept is the point where the line crosses the y-axis.
The line on this graph crosses the y-axis at -1 .

   y = (slope of the line) x + (y-intercept) .

   y = ( 0.5 ) x ( - 1 ) .

The weight of strawberries follows a normal distribution with a mean weight of 12 grams and a standard deviation of 2.5 grams. I

Viefleur [7K]

This is a problem of Standard Normal distribution.

We have mean= 12 grams
Standard Deviation = 2.5 grams

First we convert 8.5 to z score. 8.5 converted to z score for given mean and standard deviation will be:

$z= \frac{8.5-12}{2.5} =-1.4$

So, from standard normal table we need to find the probability of z score to be less than -1.4. The probability comes out to be 0.0808

Thus, the <span>probability that the strawberry weighs less than 8.5 grams is 0.0808</span>
