Answer:

If you have SSA, then the third side determines the triangle. If it is too short to intersect the other side, then it does not form a triangle. The third side can also be just the right length to meet the other side, making one triangle. Finally, the third side might be long enough to intersect the other side at two different points, creating two triangles.

Step-by-step explanation:

suppose your grades on four science exams are 99, 86, 76, and 95. what grade do you need on your next exam to have a 91 average

ahrayia [7]

99 because if you add 78+99+95+86 you get 356 and 356+99 is equal to 455 and 455 divided by 5 is 91.

A plant in the manufacturing sector is concerned about its sulfur dioxide emissions. The weekly sulfur dioxide emissions follow

egoroff_w [7]

Answer:

The correct option is b) 1.70

Step-by-step explanation:

Consider the provided information.

The weekly sulfur dioxide emissions follow a normal distribution with a mean of 1000 ppm (parts per million) and a standard deviation of 25.

Thus, μ=1000 and σ = 25

The CEO wants to know if the mean level of emissions is different from 1000.

Therefore the null and alternative hypothesis is:

$H_0:\mu =1000$ and $H_a:\mu \neq1000$

The sample size is n = 50 and $\bar x=1006$ ppm.

Now calculate the test statistic by using the formula: $z=\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}$

Substitute the respective values in the above formula.

$z=\frac{1006-1000}{\frac{25}{\sqrt{50}}}$

$z=\frac{6}{\frac{25}{\sqrt{50}}}=1.697\approx 1.70$

Hence, the correct option is b) 1.70
