Answer:
<u>A. Toltec</u>
Step-by-step explanation:
Historical records show that after the collapse of the Teotihuacan and the Zapotec empire, the Toltec empire rose to power and it became the dominant power in Mexico.
Step-by-step explanation:
If the cost of 5m cloth is Rs.375
Then cost of 80m cloth is (80m× Rs 375)÷ 5m
then the cost of is 6000 Rs. you can use the criss cross method
5m = 375 Rs
80m = ?
80 × 375 = (30,000) ÷5
?= 6000
Answer:

Im not so sure on the others, Gl!
Given that the mean of 15 bowlers that have been selected at random is distributed normally with mean 157 and std dev of 12
The probability that a random sample of 15 bowlers would have an average score greater than 165 will be:
mean=157
std dev,σ =12
std error=σ/√n=12/√15=3.0984
standardizing xbar to z=(xbar-μ)/(σ/√n)
P(xbar>165)=P(165-157)/3.0984
=P(z>2.582)
using normal probability tables we get:
P(z>2.582)=0.0049
Next we calculate the probability that a random sample of 150 bowlers will have an average score greater than 165.
μ=157
σ=12
std error=12/√150=0.9797=0/98
standardizing the xbar we get:
z=(165-157)/0.98
=P(z>8.165)
from normal table this will give us:
P(z>8.165)=0.00
