Answer:

The value of a is 2/5.

Step-by-step explanation:

Consider the provided equation.  

1.7a+0.3a=\frac{4}{5}

We need to solve the equation for a.

Add the like terms.

2a=\frac{4}{5}

Divide both the sides by 2.

\frac{2a}{2}=\frac{4}{5\times 2}

a=\frac{2}{5}

Hence the value of a is 2/5.

Evaluate the expression for x = 2 and y = 4<br> 16x^(0 +2x^(2* y^(-1)))
Paraphin [41]

Answer:

47

Step-by-step explanation:

When an expression is evaluated, the expression is either simplified or calculated.

The result of the expression is 47

The expression is given as:

Where:

x = 2 and y = 4

Substitute 2 for x and 4 for y in the expression

So, we have:

Evaluate all exponents

Evaluate all products

Evaluate like terms

Hence, the result of the expression is 47

Researchers in New Zealand interviewed 907 drivers at age 21. They had data on traffic accidents and they asked their subjects a
user100 [1]

Answer:

a)

Therefore to compare this data effectively using the rates per driver is better off like for people who do not smoke their rate will be = 59 / 452 = 13.1% while for smokers of 61+ times = 50 / 156 = 32.1% and this rate will show clearly tat more accidents where caused by people who smoked 51+ times hence it should be used for graphical representation

b) attached below

Step-by-step explanation:

A) A  useful graph is must compare rates rather than counts of accidents in the four marijuana use classes

Using the rates on a graph is better for reference like saying; that 50 crashes were caused by those who smoke 51+ times and 59 crashes is caused by those who never smoke this statistics makes it seem like smoking has no effect on the amount of accidents

Therefore to compare this data effectively using the rates per driver is better off like for people who do not smoke their rate will be = 59 / 452 = 13.1% while for smokers of 61+ times = 50 / 156 = 32.1% and this rate will show clearly tat more accidents where caused by people who smoked 51+ times hence it should be used for graphical representation

B) accident rate for Non-smokers

 = (59/452) * 100 = 13.05

accident rate for smokers between 1-10 times

= ( 36/ 229 ) * 100 = 15.72

accidents rate for smokers between 11 - 50 times

=  ( 15/50 ) * 100 = 21.42

accidents rate for smokers 51+

 =  ( 50 / 156 ) * 100 = 32.05

attached below is the required graph

Ahat [919]

Answer:

$150

Step-by-step explanation:

First use a proportion to find the answer:

40/100=60/x

Now we solve for x

60*100=6,000

6,000 divided by 40= 150

x=150
