If you work out the constants it says:
25+x²=100
Which simplifies to x=√75 or x=-√75
Answer: none of the above
Step-by-step explanation: when performing an hypothesis test and we want to make conclusion by comparing the p-value with the level of significance α
When p is greater than α, we reject the null hypothesis because it simply implies that we have a larger chance to commit a type 1 error ( α is the probability of committing a type 1 error an error where we reject the null hypothesis instead of accepting it ) which means we reject the null hypothesis.
When p is lesser than level of significance α, it means that we have a lesser chance of committing a type 1 error, which means we accept the null hypothesis.
Answer: #7 is A and #8 is D
Step-by-step explanation:
Answer:
B. 50°
Step-by-step explanation:
∠PLM+ ∠PML =60+70 =130°
So, ∠MPL = 180°-130°=50°
According to the opposite angle theorem,
∠ KPN = ∠MPL which is 50°
Answer:
a = -15, b = -.5, c = -1
Step-by-step explanation:
1/3a = -5 --> multiply each side with 3 --> a = -15
12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5
.1 = -10c --> multiply each side with -10 --> c = -1
