Answer:
p-value = 0.369
Step-by-step explanation:
Test of hypothesis which has its the alternative hypothesis as Ha:μ1−μ2≠0 is a two tailed test. Therefore, P-value for a two-tailed test with test statistic t≈−0.90 and the number of degrees of freedom = 208
P-value = 2 X P( t(208) < - 0.90)
= 2 X 0.1846
= 0.369
Answer:
1. 5 / 6
2. 1 / 3
3. 3 / 6 or 1 / 2
Step-by-step explanation:
The probability that A is not yellow is 5 / 6
The probability that B is blue is 1 / 3
The probability that A is red is 3 / 6 or 1 / 2
66.6667%
Now we can see that our fraction is 66.666666666667/100, which means that 4:6 as a percentage is 66.6667%.
Answer:
79.5 + 5.5x = Y
Step-by-step explanation:
Sumo wrestler gained 5.5 kg per month
After 11 month, he weighed 140 kg.
Let x be his current weight.
Then x + 11(5.5) = 140
x = 140 - 60.5
x = 79.5
If Y is the weight of the wrestler after t months, then the linear equation would be:
79.5 + 5.5t = Y
Answer:
1
Step-by-step explanation:
Three side lengths that meet the requirements of the triangle inequality will form exactly one triangle.
_____
The triangle inequality requires the sum of the short sides be at least as long as the long side. Here, we have 3 + 4.69 = 7.69 > 7, so we satisfy the triangle inequality.
The side lengths can be arranged in clockwise or counterclockwise order, least to greatest. Each triangle is a reflection of the other, so they are considered to be the same triangle (congruent).
