Even though I don't see the paragraph it would be frightened because that's the closest to scared. Distressed is more of a synonym to worried

One type of insect is 0.0052 meter long. what is the length in scientific notation.

sp2606 [1]

Here, we need to write the length of the insect in scientific notation.

The given length of the insect is 0.0052 meter

Now, to write 0.0052 meter in scientific notation we need to follow this:

Scientific notation always start with non-zero digit followed by a decimal point.

Since in our number the decimal is needed to be moved three places to the right to get the first non-zero digit.

The exponent of the 10 is $-3$ .

$10^{-3}=\frac{1}{1000} =0.001$

Therefore, our number 0.0052 can be written as:

$5.2 \times 10^{-3}$

Hence, the require scientific notation is $5.2 \times 10^{-3}$ .

Answer:

Probability is 0.3506

Step-by-step explanation:

We are given

mean is 8mm

so, $\mu=8$

standard deviation is 2.2 mm

so, $\sigma=2.2$

x-varies from 7mm to 9mm

At x=7:

we can use formula

$z=\frac{x-\mu}{\sigma}$

we can plug values

$z=\frac{7-8}{2.2}$

$z=-0.45455$

At x=9:

we can use formula

$z=\frac{x-\mu}{\sigma}$

we can plug values

$z=\frac{9-8}{2.2}$

$z=0.45455$

So, z is between -0.45455 and 0.45455

$-0.45455\leq z \leq 0.45455$

now, we can use normal distribution table

and we get

Probability is 0.3506

Use the quadratic formula to solve x² + 9x + 10 = 0.<br><br> What are the solutions to the equation?

jok3333 [9.3K]

Answer:

$-1.30\ and\ -7.70$ (2 decimal places)

Step-by-step explanation:

Quadratic Formula: $x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

-----------------------------------------------

$x^2+9x+10=0$

Plug in values:

$x=\frac{-9\pm \sqrt{9^2-4\cdot \:1\cdot \:10}}{2\cdot \:1}$

First value of x:

$x=\frac{-9+\sqrt{41}}{2}=-1.30$ (2 decimal places)

Second value of x:

$x=\frac{-9-\sqrt{41}}{2}=-7.70$ (2 decimal places)
