What unit is used to measure memory size?

Fill in the missing mass number and atomic number for each of these particles or types of radiation.

• alpha ($\alpha$) $\ce{_{ - }^{ - }He}$
• beta ($\beta$) $\ce{_{ - }^{ - }e}$
• gamma $_{ - }^{ - }\gamma$
• neutron $\ce{_{ - }^{ - }n}$

The actual thin film built for windows reflects about what percent of the incident infrared radiation at 1000 nm? (a) 10, (b) 30, (c) 50, (d) 70, (e) 90.

Find the unit rate. $8.50:5 ounces

If the Earth-Sun distance were doubled, the intensity of radiation from the Sun that reaches the Earth's surface would $(a)$ quadruple. $(b)$ double. $(c)$ drop to $\frac{1}{2}$, $(d)$ drop to $\frac{1}{4}$.

A consensus forecast is the average of a large number of individual analysts' forecasts. Suppose the individual forecasts for a particular interest rate are normally distributed with a mean of $5.0$ percent and a standard deviation of $1.2$ percent. A single analyst is randomly selected. Find the probability that his/her forecast is:

At least $3.5$ percent.

How could Henri Becquerel and other scientists determine that there were three different kinds of radiation before having determined the electric charges or masses of the $\alpha , \beta$, and $\gamma$ rays?

How is the unit of heat known as a 'calorie' defined?

Compute the integral of $x + y$ over the surface of the unit sphere.

What is one advantage of a Mercator projection? What is one disadvantage?

Determine whether the reasoning in this exercise is an example of deductive or inductive reasoning.

My dog barked and woke me up at $1$:$02$ a.m., $2$:$03$ a.m., and $3$:$04$ a.m. So he will bark again and wake me up at $4$:$05$ a.m.

Find the unit rate. $320/4 people

Find two unit vectors parallel to (2,3).

The amount of interest you could earn in six months on a $\$ 12,000$ deposit in the Fiftieth State Bank that pays quarterly interest is $\$ 180.68$. Could you earn more interest for the half-year by depositing f $\$ 12.000$ in an account that pays a $3.1 \%$ annual interest rate? How much more?
