How many dots are in the 4th step?

Mkey [24]

Answer:

Step-by-step explanation:

if you look at the diagram the dot goes up 1 each. It also makes another row which makes 4 rows total. Since 3 contains 7 dots and 3 rows we would do 8 in 4 rows. 8 x 4 is 32.

Hope this helped!

"A researcher wants to determine if consuming oatmeal regularly reduces the level of bad cholesterol. She finds 120 adults over

Inessa05 [86]

Answer:

An experimental research and particularly a quasi experimental study.

Step-by-step explanation:

An experimental research is one where the investigator study the effects from random samples he got and tested. the investigator manipulates parameters to considers some underlying factors in order to arrive at a conclusion. it is usually used to investigate relationships between variable and make comparison. In this case the investigator is conducting a research on how the consumption of oatmeal in adults reduces the level of bad cholesterol, he measures and study the level of bad cholesterol for 6months and then compare their results.

for example, I can conduct an extensive experimental study on the long term effects of exhaust fumes on the passengers (particularly adults between the ages of 25-50) of public transport in Nigeria. this will be studied and their effects will be compared and a conclusion will be reached on the exposure and the non exposure as the case maybe. most underlying conditions of experimental study are under the direct control of the researcher of the investigator. there are three different types of experimental research ; Pre-experimental study, quasi-experimental study and true-experimental study.

A parachutist descends 44 feet in 4 seconds. Express the rate of the parachutist's change in height as a unit rate.

Montano1993 [528]

The unit rate of the parachutist change in height is 11 feet per second.

• In Mathematics, Unitary method is a technique for solving a question by first finding the value of a single unit and then finding the required value by multiplying the number by value of single unit .

• We use unitary method to find the ratio of one thing with respect to other thing.

• There are two types of unitary method one is Direct Variation and the other is Inverse variation.

We have the rate of descend as 44 feet in 4 sec.

So, in 1 second it will be = 44 / 4 = 11 feet.

Which is the unit rate.

Therefore, the unit rate of descend for the parachutist is 11 feet per second.

How to do the problem

MrMuchimi

Order of operations are:
1. Parentheses (simplify inside 'em)
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

So, on your first one:
Parentheses first:
8(3+4)-2*8/(5-3)
8(7)-2*8/(2)

There are no exponents so multiplication and division:
56-16/2
56-8

Finally, addition and subtraction:
56-8=48

Your second problem is a bit more complicated but follows the same rules:
 $( 8^{2}+(13-4) ^{2} )/5$

Parentheses first:
 $( 8^{2}+ 9^{2})/5)$

Now, exponents. Even though they are inside parentheses, we can't go further until we simply those.
(64+81)/5

Now back to parentheses:
(145)/5

Division:
145/5=29

Hope that helps
