Please answer the question it’s for my math SAT

Answer: D.

This is tricky.

Think of the equation as an equation for a line

where in this case.

$C=5/9(f-32)$

$C=5/9f-5/9(32)$

You can see the slope of the graph is $5/9$ which means that for an increase of 1 degree Fahrenheit, the increase is $5/9$ .

$c=5/9(f)$

$c=5/9(1)=5/9$

Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of $9/5$ Degrees Fahrenheit

$c=5/9(f)$

$1=5/9(f)$

$f=9/5$

Since $9/5=1.8$ Statement 2, is true.

The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of $5/9$ degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:

$c=5/9(f)$

$c=5/9(5/9)$

$c=25/81$ which is ≠ 1)

An increase of $5/9$ degree Fahrenheit leads to an increase of $25/81$

not 1 degree, Celsius, and so Statement III is not true.

The final answer is D.

hi there!

 $\large \rm = \color{brown} 27.6272 \: \\ \tt in \: \: alternate \: \: form \\ \\ \large \tt \color{cyan} \frac{17267}{625} , \color{red}27 \frac{392}{625}$ 

<h2 />

Step-by-step explanation:

 $\tt1.13 + 2.84 \times 9.33$ 

multiply the number

 $\tt \color{green}1.13 + 26.4972$ 

add the number

 $= \tt \color{green}27.6272 \\ \\ \tt \color{pink}or \: \: in \: \: alternate \: \: form \\ \\ \tt \color{purple} \frac{17267}{625} \tt \color{blue} \: , \: 27 \frac{392}{625}$

Events A and B are independent. The probability of A occurring is 2/5. The probability of B occurring is 1/4. What is P(Aand B)

Elena L [17]

Answer:

The value of P(A and B) is 1/10

Step-by-step explanation:

In case of independent events, the probability of one event doesn't depend on the probability of other events.

Therefore, for an independent events

P(A and B) = P(A) × P(B)

P(A and B) = 2/5 × 1/4

P(A and B) =2/20

P(A and B) =1/10

Therefore, the value of P(A and B) is 1/10
