I'm confused on what you're asking, but this is scientific notation on the first one of 0.0000855. 8.55 x 10^-5

Answer:

$8.55\times 10^{-5}$

Step-by-step explanation:

Given number,

0.0000855,

Since, scientific notation is way to write a large or small number as the product of a number between 0 to 9 and an exponent of 10,

Also, when we move the decimal towards right side to obtain the number between 0 to 9 the exponent of 10 is negative value of shifting otherwise it is positive value of shifting,

Thus, by the above explanation,

The scientific notation of the number 0.0000855 is $8.55\times 10^{-5}$

To convert a mixed fraction into an improper fraction:

$a\frac{b}{c} =\frac{(a\cdot c)+b}{c}$

$49 \frac{1}{2} = \frac{(49\cdot 2)+1}{2} = \frac{98 +1}{2} = \boxed{\bf{\frac{99}{2}}}$

When Isaac commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 44 minutes and a s

mario62 [17]

Answer:

[34,54]

Step-by-step explanation:

-The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.

Where:

68% is the first standard deviation
95% is the second standard deviation about the mean
99.7% is the 3rd standard deviation about the mean.

-Therefore. the middle 95% interval is calculated as:

$CI=\mu+2\sigma\\\\=44\pm 2(5)\\\\=44\pm 10\\\\=[34,54]$

Hence, the interval is [34,54]

3p + 2q = 14 10p + 6q = 44 What is p and what is q

Airida [17]

Answer:

p = 2 ; q = 4

Step-by-step explanation:

Given tbe equation :

3p + 2q = 14 - - - (1)

10p + 6q = 44 - - -(2)

What is p and what is q

This is a simultaneous equation ; using elimination method :

Multiply (1) by 6 and (2) by 2

18p + 12q = 84 - - - - (3)

20p + 12q = 88 - - - (4)

Subtract (3) and (4)

-2p = - 4

p = 4/2

p = 2

Put p = 2 in (1)

3p + 2q = 14

3(2) + 2q = 14

6 + 2q = 14

2q = 14 - 6

2q = 8

q = 8/2

q = 4

p = 2 ; q = 4

Circumference of a 4" circle?

lesya692 [45]

Answer:

4π ≈ 12.5663706144

Step-by-step explanation:

The circumference of a circle is 2πr, or 2*pi*radius

Suppose the circle has a diameter of 4 inches. A diameter is 2x the radius, of which we are looking for, therefore:

4÷2=2 inches (radius length)

Now that we have the radius, let us substitute to find the circumference:

2πr=

2π2=

4π≈

12.5663706144

I hope this helped! Let me know if you have any further questions :)

Which function BEST expresses the linear relationship displayed by the scatter plot?

Harrizon [31]

Answer:

Step-by-step explanation:

We want a line of best fit, which means we want to create a line that the data points will lie closest to.

One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.

Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:

(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4

Eliminate A and B.

Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.

The answer is C.
