b.17.50°

c.26.57°

d.35.53°

Answers

From sin theorem we know that:

sin(A)/a = sin(C)/c, so sin(A) = asin(C)/c = sin(35deg)/2. So A = arcsin(sin(35deg)/2) = 16.67.

The answer to your question is A. I hope that this is the answer that you were looking for and it has helped you.

Weights (kg) of poplar trees were obtained from trees planted in a rich and moist region. The trees were given different treatments identified in the accompanying table. Use a 0.05 significance level to test the claim that the four treatment categories yield poplar trees with the same mean weight. Is there a treatment that appears to be most effective? E Click the icon to view the data table of the poplar weights. Determine the null and alternative hypotheses. Но H1

Answers

Answer:

Null hypothesis (H0): The four treatment categories yield poplar trees with the same mean weight.

Alternative hypothesis (H1): The four treatment categories yield poplar trees with a different mean weight.

Based on the data table, it appears that Treatment A yields the highest mean weight for the poplar trees. Therefore, Treatment A appears to be the most effective.

Add brainliest, if this is useful.

Final answer:

To test the claim that the four treatment categories yield poplar trees with the same mean weight, we will use a significance level of 0.05. The null hypothesis (H0) assumes that the treatment categories yield poplar trees with the same mean weight, while the alternative hypothesis (H1) assumes that at least one treatment category yields poplar trees with a different mean weight.

Explanation:

To test the claim that the four treatment categories yield poplar trees with the same mean weight, we will use a significance level of 0.05. This means that if the p-value is less than 0.05, we will reject the null hypothesis and conclude that there is evidence to support the claim that the treatment categories yield poplar trees with different mean weights. On the other hand, if the p-value is greater than or equal to 0.05, we will fail to reject the null hypothesis and conclude that there is not enough evidence to support the claim that the treatment categories yield poplar trees with different mean weights.

The null hypothesis (H0) assumes that the treatment categories yield poplar trees with the same mean weight. The alternative hypothesis (H1) assumes that at least one treatment category yields poplar trees with a different mean weight.

UCU-CGA-GCC-GUU-GGG-UGA how do I convert this into an amino acid using the codon chart, i've been on this forever

Answers

So u get a codon chart it'll look like a circle with a bunch of letters. Then you use the letters u are given for every dash such as UCU and you go biggest to smallest letter until you hit an amino acid or stop then what you write down is that amino acid you hit. For an example, we'll use UCU. You go to the big letter U inside that big U will be a smaller C and inside that C will be a smaller U which leads to an amino acid or a stop codon. And you do this with every group of 3 letters. If one is missing it stops prematurely and if there is an extra when it may have a mutation. I hope that helped! If not there are YouTube videos out there that can help.

Melissa is studying a Gram-stained slide of curd bacteria. She sees many rod-shaped, violet-colored bacteria. What type of bacteria are they?

Answers

Answer:

By the observation, the rod shape violet-colored bacteria could be a Gram-positive bacillus which is Lactobacillus spp.  in curd.

Explanation:

Gram-stain is a staining method to isolate and study the Gram-positive or Gram-negative bacteria with the help of the crystal violet dye. Crystal violet dye stains both Gram-positive and Gram-negative bacteria in purple stain. After decolorization, Gram-negative bacteria appears to be pink in color, however,Gram-positive bacteria remain purple.

According to bacteria structure, they term as bacillus (rod), strepto (clusters or threads) or Diplo (in pairs).

Thus, according to the observation, the rod shape violet colored bacteria are Gram-positive bacillus which is Lactobacillus spp. in curd.
Rod shaped = bacilli
Purple =Gram positive
The bacteria is Lactobacillus

A candle and a firework both can be ignited with a spark, but they release different amounts of energy as they burn. Compare and contrast the potential energy diagrams that would represent each of these burning processes.

Answers

The reactions of both candle and firework is exothermic. This means that the products have a lower potential energy than the reactants. The difference is that fireworks release more energy than the candle. In the energy curve diagrams, the fireworks will begin with a more potential energy.
