Answer:
Blue Ballon = 16
Yellow Ballon = 23
Green Ballon = 26
Red Ballon = 32
Total puffs = 1000
23y + 16(2y) + 32y + 26(y/2) = 1000
23y + 32y + 32y + 13y = 1000
100y = 1000
y = 1000/10
y = 10
Therefore, russell
filled 10 yellow balloons.

Answer:
m∠B =
.
Step-by-step explanation:
Since the three sides of the triangle are given, then we apply cosine rule.
=
+
- 2ac Cos B
But, a = 660 cm, b = 680 cm, and c = 100 cm.
So that;
=
+
-2(660 x 100) Cos B
462400 = 435600 + 10000 - 132000 Cos B
462400 = 445600 - 132000 Cos B
132000 Cos B = 445600 - 462400
= -16800
Cos B = 
= -0.1273
B =
-0.1273
= 
Thus, measure of ∠B is
.
Answer:
The responses to these question can be defined as follows:
Step-by-step explanation:

Test statistic ta
The critical values
It is in the region of dismissal. We dismiss the 10% significant null hypothesis.
P - value is greater than the level of significance a= 0.05
Null hypothesis we don't reject. At a 95% level, the claim is justified.

P - value below the meaning level a = 0.10, we reject the hypothesis null. At a level of 90% the claim is not justified.
