<u><em>Answer</em></u>
= 3.405 × 10⁻⁴
<u>Explanation</u>
If the question is correctly written, then it is very easy.
First, take the like terms on one side.
493x = 3432x+1
493x - 3432x = 1
-2939x = 1
Dividing both sides by -2939 to get the value of x.
x = 1/(-2939)
= - 0.0003405
= 3.405 × 10⁻⁴
Answer:
20:£1
Step-by-step explanation:
To simplify a ratio is like like simplifying a fraction
Take 4/8 as an example. Find a number you can divide both numbers with. In this case, it's 4. 4 divided by 4= 1, and 8 divided by 4= 2. So, the simplified version of 4/8 is 1/2. Similarly, with the ration 60:£3, you find the number you can divided both numbers with. In this case, it is 3. 3 divided by 3= 1, and 60 divided by 3= 20.
Final Answer: 20:£1
Answer:
Which Number Is x, You Didnt Specify
Answer: 0.2643
Step-by-step explanation:
Given : The proportion of adults are unemployed : p=0.077
The sample size = 300
By suing normal approximation to the binomial , we have
Now, using formula 
, the z-value corresponding to 26 will be :-
Using standard distribution table for z , we have
P-value=
Hence, the probability that at least 26 in the sample are unemployed =0.2643
