These were the choices I found on the internet:
0.1135 
0.2450
0.9423 
<span>0.9932

Other sources can confirm that it is not the second choice. So I'd say it's the third one. Multiply the 98% to the 25% chance of having no allergy to get 0.2450. And for the 0.26, 98% times the 2% percent of error add this to the percent of having no allergy - 0</span>.245 / 0.26 = 0.9423 or 94.23%

The scientist came to the conclusion that the hypothesis was incorrect. Why is the scientist's conclusion flawed?
Nonamiya [84]

Answer:

C. The scientist's conclusion is flawed because the number of hours of sunlight changed and, therefore, the experiment is not controlled.

Explanation:

A controlled experiment is an experiment used to test a single variable at a time. The variable that is being tested is called the independent variable, and it is directly manipulated by a scientist. The rest of the variables need to remain unchanged in order not to get wrong results like the scientist in the given scenario.

As the scientist is trying to see how gamma rays affect marigolds, only the gamma ray exposure is supposed to change throughout the experiment. The amount of water remained the same, but the number of hours of sunlight didn't. That's why we don't know what exactly affected the growth of marigolds - the sunlight or the gamma rays? And that's why the scientist's conclusion is flawed.

NEED ENGLISH HELP VERY QUICKLY!!!!
gregori [183]

The dance squad had eight members when it won the competition.

A relative clause can be used as an adjective or an adverb. Relative clauses must contain both a subject and a verb. They also begin with a relative pronoun (question words and that). The relative clause in the last option is "when it won the competition". It starts with "when" which is a relative pronoun. It describes when the action takes place which makes the entire clause an adverb. It has a subject "it" and a verb "won". Options B and C should be immediately thrown out because they do not have a relative pronoun. Option A does not work because there is no subject after "that".

Can someone dumb the question down for me I don't get it......ill do anything for an answer​
tatyana61 [14]

So first it is asking you to basically tell what you think the “covenant” is. While explaining the covenant, make sure to add in there what God’s expectations were for the Israelites who where apart of the covenant. As well as if they followed or didn’t follow those expectations, what God did for/to them. Make sure to add verses and lines to help explain it more and give proof of your words! Hope it helps!
