<h3>Given:</h3>
<h3>To find:</h3>
How much is $100 in ZA rands.
<h3>Solution:</h3>
Let the unknown be "x"

We'll have to do cross multiplication.
So we'll have to multiply 100 and 17.

Answer:
The null and alternative hypothesis are:

There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
Step-by-step explanation:
Consider the provided information.
The claim that the mean tornado length is greater than 2.6 miles.
If there is no statistical significance in the test then it is know as the null which is denoted by
, otherwise it is known as alternative hypothesis which denoted by
.
Therefore, the required null and alternative hypothesis are:

significance level α =0.05
From the given table the test statistic T=2.230166
P-value is 0.0131
0.0131<0.05
P value is less than the significance level, so reject the null hypothesis.
There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
Answer:
Number of marbles with Williams at the starting = 192
Step-by-step explanation:
Let total number of marbles with Williams = m
He lost marbles = 25% of the total number
= 
= 
Remaining marbles with Williams = m - 
= 
He gave marbles to his brother =
th of the remaining marbles
= 
= 
Remaining marbles after giving marbles to his brother = 120
Therefore, 


m = 
m = 192
Number of marbles with Williams at the starting = 192
Answer: After 4 months they will have the same number of Stamps
Xian and Kai will have 124 stamps each one.
Step-by-step explanation:
60+16x = 76+12x (Subtract 12 from both sides)
-12 -12
60+4x = 76 (Subtract 60 from both sides)
-60 -60
4x/4x = 16/4x (Divide 16 by 4)
X = 4
