The required value is $2\times10^9$

Step-by-step explanation:

Weight of ants = $4\times10^{-3}$

Weight of elephant= $8\times10^6$

We need to find, the total weight of about how many ants equals to the weight of an oversized elephant.

The equation given is:

$4\times10^{-3} \times a = 8\times10^6$

We need to find a:

Solving:

$4\times10^{-3} \times a = 8\times10^6\\a=\frac{8\times10^6}{4\times10^{-3}}\\if \,\,10^a/10^-b \,\,then\,\, 10^{a+b}\\a=2\times10^{6+3} \\a=2\times10^9$

So, the required value is $2\times10^9$

How are central tendency and standard deviation related

loris [4]

Answer:

Measure of central tendency is a value that represents a typical, or central, entry of a data set. The most common measures of central tendency are: • Mean (Average): The sum of all the data entries divided by the number of entries. ... The standard deviation measure variability and consistency of the sample or population.

The function h(x) has an x-intercept of 2 and a y-intercept of 8. what is the slope of h(x)

Mekhanik [1.2K]

Answer:

-4

Step-by-step explanation:

The slope of a function f(x) passing through two points of coordinates $(x_1,y_1)$ and $(x_2,y_2)$ is given by

$m=\frac{y_2-y_1}{x_2-x_1}$

Therefore, in order to find the slope of the function h(x) of this problem, we have to find the coordinates of 2 points.

We know that h(x) has an x-intercept of 2: the x-intercept is the point where the function crosses the x-axis, so the coordinates of this point are

$(2,0)$

Because at x = 2, the value of y is zero.

We also know that h(x) has an y-intercept of 8: the y-intercept is the point where the function crosses the y-axis, so the coordinates of this point are

$(0,8)$

Because at x = 0, the value of y is 8.

Therefore, we can now use these 2 points to calculate the slope of the function:

$m=\frac{8-0}{0-2}=-4$

Joel can read around 16 sentences per minute of his current novel. He wants to finish his reading before the movie comes out nex

Ainat [17]

Answer:

2.7 hours or 2 hrs, 42 min

Step-by-step explanation:

to find the total number of sentences remaining we can multiply 130 sentences times 20 pages remaining to get

2,600 sentences

if we divide that number by 16 we'll get the number of minutes he needs to finish the novel

2600/16 = 162.5 minutes which, when divided by 60, is 2 7/10 hours

7/10 = 42/60 so it comes out to 2.7 hours or 2 hrs, 42 min
