Answer:

Option A.

Step-by-step explanation:

Option A. 3(x + 2) = 3x + 6

L.H.S. = R.H.S.

So equivalent expressions.

Option B. (3x + 2x) = 5x ≠ x² ( 3 + 2 )

Expressions are not equivalent L.H.S. ≠ R.H.S.

Option C. R.H.S. 3(x+2) = 3x + 6 ≠ L.H.S. (3x + 2)

Expression are not equivalent.

Option D. L.H.S. -3(2+x) = -6 -3x ≠ - 6x - 3 (R.H.S.)

Therefore, expressions are not equivalent.

Option A. is the answer.

3t-1=8
3t=8+1
3t=9
3t divide by 9
Will give you 3
So your t value would be 3

Explanation: you would have to bring the -1 over to the 8, making the 1 positive. Then you would add up 8 nd 1.
And just divide the two numbers so 9 divide by 3. And you would have your answer T=

Riya looks at the temperature in the kitchen. What is the temperature in the kitchen to the nearest division

insens350 [35]

Answer:

24 degree Celsius

Step-by-step explanation:

Temperature may be defined as the intensity or the degree of heat that is present in any substance or present in the environment. It is the measure of hotness or coldness of any item or surroundings. Temperature is measured with the help of a comparative scale which shows the how hot or cold the place is or item is.

In the context, Riya uses a comparative scale like the thermometer to measure the temperature of the kitchen. The mercury level on the scale rises and stops at a point indicating the temperature of the kitchen.

Thus the temperature of the kitchen according to the scale is $24 ^ \circ C$ .

A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independen

Andrews [41]

Answer:

0.044

Step-by-step explanation:

n=9,p=0.9, x =6.

Apply Binomial probability we get

Sum P(x)=C(n,x) $p^{x} (1-p)^{n-x}$ for x=6

Putting in the formula ,

we get

P(x) = C(9,6) $0.9^{6} 0.1^{3}$

84 X 0.531441 X 0.001

= 0.044
