A consumer wanted to compare two types of battery storage. One type is refrigerated and the other is room temperature. It is a common belief that refrigerated batteries last longer. This belief is tested by placing 10 fully charged batteries into each type of storage and then measuring the percentage of charge remaining after thirty days. A coin tip was used to determine which type of storage each battery would be placed in first. Results indicated that there was no difference in the two types of storage Complete parts (a) through in below.
What type of experimental design is this?
A) Matched pairs design
B) Completely randomized design
C) Randomized block design
D) Case-control study

Answers

Answer:

A) Matched pairs design

Step-by-step explanation:

In experimental design, the match pairs experimental design is one that often involves only two treatment conditions; which in this case are the 'refrigerated and the room temperature battery storage types'.

Thus, these two treatment conditions form a matched pair because we are told that 10 fully charged batteries are placed into each type of storage.

Janet can make 4/5 of a necklace in 20 minutes. At this rate, how many necklaces, to the nearest tenth of a necklace, can Janet make in 1 hour?

Answers

Answer: 4 necklaces

Step-by-step explanation: 4/5 x 5 = 4

hope this helps

Answer:

Janet makes 2.4 necklaces in 1 hour

Step-by-step explanation:

first you need to find how many minutes it takes to make one necklace.

to do this, divide 20 by 4 and multiply by 5.

20/4 = 5

5 * 5 = 25

janet makes one necklace every 25 minutes.

one hour is 60 minutes.

60/25 = 2.4

4(x-1)=-8 how do i answer this

Answers

Answer: x= -1

Step-by-step explanation:

4(x-1)=-8

First distribute

4x-4=-8

Now add 4 to -8

4x=-4

Now divide by 4

X=-1

The answer is x = -1

Step-by-step explanation: When it comes to solving for a variable (x) you have to distribute if there is parenthesis and then use inverse operations to get the answer.

4(x-1)=-8 Distribute

4x - 4 = -8 Subtract 4 from both sides

4x = -4 Divide 4 on both sides

x = - 1 and that is your answer

What is 200 as a percent?

Answers

Answer:

Step-by-step explanation:

So, we know that 200 can also be written as 200.00 which does not change the value of the number. Now, we can turn it into a percentage by moving the decimal point to digits back: 200.00 --> 20000. So, this means that 200 is 20000%.

20000% would be the answer

Complete Question

A psychologist has designed an index to measure the social perceptiveness of elementary school children. The index is based on ratings of a child's responses to questions about a set of photographs showing different social situations. A random sample of 16 elementary school children was chosen, and their index measurements were recorded. Assume that the index measure in the population is normally distributed. The 95% confidence interval created from this data is (56.29, 65.09). This interval indicates:__________.Choose one or more:

a. The average index of elementary school children must be 60.69.

b. The standard deviation of the sample is about 10% smaller than the population standard deviation.

c. That if we take many samples from this population 95% of them will have a sample mean between 56.29 and 65.09.

d. 95% of all elementary school children in this district have indices between 56.29 and 65.09.

e. 4.40 is 95% of the true average of the index for all elementary school children.

f. We are 95% confident that the average index for all elementary school children is between 56.29 and 65.09.

Answer:

The correct option is  a and  f

Step-by-step explanation:

From the question we are told that

    The sample size is  n =  16

     The 95% confidence interval is  (56.29, 65.09)

Generally the sample mean(average index of elementary school children) is mathematically represented as

     [tex]\= x  =  \frac{65.09 + 56.29}{2}[/tex]

=>  [tex]\= x  =  60.69 [/tex]

 

A slug travels 3 centimeters in 3 seconds. A snail travels 6 centimeters in 6 seconds. Both travel at constant speeds. Mai says, “The snail was traveling faster because it went a greater distance.”

Answers

Answer:

Mai is wrong since both travel the same distance in the same amount of seconds

Step-by-step explanation:

3 centimeters in 3 seconds is 1 centimeter a second for the slug

6 centimeters in 6 seconds is 1 centimeter a second for the snail

so both travel the same distance

Answer:

No, she is wrong. They are both going the same pace.

Step-by-step explanation:

3 centimer divided by 3 is 1. 1 cm a second. 6 centimeters didvided by 6 is 1.

1 cm a second. Hence they are both going the same speed. If you don't understand anything comment and ill explain more. Please heart and 5 stars and brainlest if you don't mind

6. In case of short
circuit............current will flow in
that circuit. *​

Answers

Answer:

As suggested in the name itself:

a short circuit makes the circuit 'short' which causes the resistance of the circuit to be close to none

When the resistance is decreased, the amount of current flowing in the circuit increases (ohm's law: R ∝ 1/ I)

Therefore, in case of a short-circuit. More current will flow in the circuit

A metal wire has a circular cross section with radius 0.800 mm. You measure the resistivity of the wire in the following way: you connect one end of the wire to one terminal of a battery that has emf 12.0 V and negligible internal resistance. To the other terminal of the battery you connect a point along the wire so that the length of wire between the battery terminals is d. You measure the current in the wire as a function of d. The currents are small, so the temperature change of the wire is very small. You plot your results as I versus 1/d and find that the data lie close to a straight line that has slope 600 Am.
