Answer:
B. 9
Step-by-step explanation:
m∠U = 2x°
m∠V = 4m∠U
= 4(2x°)
= 8x°
Complementary angles add up to 90°.
∠U + ∠V = 90°
2x° + 8x° = 90°
10x° = 90°
x = 90° ÷ 10°
= 9
Answer:
Yes there is sufficient evidence.
Null hypothesis; H_o ; μ = 445
Alternative hypothesis; H_o ; μ ≠ 445
Step-by-step explanation:
The null hypothesis states that there is no difference in the test which is denoted by H_o. However, the sign of null hypothesis is denoted by the signs of = or ≥ or ≤.
Meanwhile, the alternative hypothesis is one that defers from the null hypothesis. This therefore implies a significant difference in the test. Thus, the signs of alternative hypothesis is denoted by; < or > or ≠.
Now, the question we have is a two tailed test. Thus;
The null hypothesis is;
bag filling machine works correctly at the 445 gram setting which is;
H_o ; μ = 445
The alternative hypothesis is;
bag filling machine works incorrectly at the 445 gram setting which is;
H_o ; μ ≠ 445
The answer is (4x-5)(5x^2+1)
Answer:
the median is in the middle so count up to ten and eleven and check what numbers are there.
so it's 31+34= 65
65÷2=32.5
