Answer:
60
Step-by-step explanation:
because half of children is 50. 120÷50=60
Answer:
2 hours
Step-by-step explanation:
Train B's speed: 4/3 × 60 = 80
Combined speed = 80 + 60 = 120
Time = 240/120 = 2
Answer:
X = 17√3
Y = 34
Step-by-step explanation:
TO calculate the values of X and y we use SOHCAHTOA.
<h3>
Calculating for X</h3>
tan 30 = opposite/adjacent
tan30 = 17/X
Cross multiply
tan30 ×X = 17
Divide bothsides by tan30
<h3>Note: tan30= 1/√3</h3>
X = 17/1/√3
X=17√3
<h3 /><h3>X= 29.4</h3>
X = 29 ( approximately)
<h3>Calculating for y</h3>
<h3>
Cross multiply</h3>
<h3>
Divide bothsides by sin30</h3>
Answer:
{0.16807, 0.36015, 0.3087, 0.1323, 0.02835, 0.00243}
Step-by-step explanation:
The expansion of (p+q)^n for n = 5 is ...
(p+q)^5 = p^5 +5·p^4·q +10·p^3·q^2 +10·p^2·q^3 +5·p·q^4 +q^5
When the probability p=0.3 and q = 1-p = 0.7 the terms of this series correspond to the probabilities of 5, 4, 3, 2, 1, and 0 favorable outcomes out of 5 trials.
For example, p^5 = 0.3^5 = 0.00243 is the probability of 5 favorable outcomes in 5 trials where the probability of each favorable outcome is 0.3.
___
The attachment shows the calculation of these numbers using a graphing calculator. It lists them in reverse order of the expansion of (p+q)^5 shown above, so that they are the probabilities of 0–5 favorable outcomes in the order 0–5.
