Answer:
8
Step-by-step explanation:
Perimeter is 284 means the sum of the side measurements is 284.
That is, we have to solve:
Combine like terms:
Simplify:
Subtract 12 on both sides:
Simplify:
Divide both sides by 34:
Simplify:
<span>Three powers with whole number bases that have values greater than 120 and less than 130 are:
</span>11² = 11 x 11 = 121
<span>5³ = 5 x 5 x 5 =125 </span>
<span>2⁷ = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
</span>
Remember Pedmas. 1) -12+3(3)+5 = -12+9+5 = 2. 2) 3(15-12)-5 = 3(3)-5 = 4
Answer:
5/9
Step-by-step explanation:
total present = males + females = 60 + 48 = 108
The desired ratio is ...
males/total present = 60/108 = 5/9
It depends on what the level of significance (alpha) is.
Since alpha is not stated, I'll assume that alpha = 0.05 by default.
Because the p-value is smaller than alpha, we reject the null hypothesis.
Therefore, we conclude that the alternative hypothesis is correct and the proportion of heads is greater than 0.5
