Answer:

m , m

Step-by-step explanation:

we know that

In a parallelogram, opposite angles are congruent and consecutive angles are supplementary

so

m ----> equation A

mS=180\° -----> equation B

we have

m>S=70\°

substitute in the equation B and solve for m<R

m

m

m -----> substitute in equation A

m

This probability distribution shows
Charra [1.4K]

Answer:

The probability that a student earns a grade of A is 1/7.

Let E be an event and S be the sample space. The probability of E, denoted by P(E) could be computed as:

P(E) = n(E) / n(S)

As the total number of students = n(S) = 35

Students getting the grade A = n(E) = 5

So, the probability that a student earns a grade of A:

                     P(E) = n(E) / n(S)

                             = 5/35

                             = 1/7

Hence, the probability that a student earns a grade of A is 1/7.

In a memory​ experiment, Alice is able to memorize words at a rate given by m '(t)= - 0.009t^2 + 0.6t. In the same memory​ exper
White raven [17]

Answer:

1) Ben, 2) \Delta = 2, 3) \dot m = 2.7, 4) \dot M = 2.9

Step-by-step explanation:

1) Ben has a higher rate of memorization, since the coefficient of the second power is lesser than the one from Alice.

2) The number of words can be estimated by integrating the function:

Alice

\Delta m = -0.003\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}

\Delta m = 27

Ben

\Delta M = -0.001\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}

\Delta M = 29

\Delta = \Delta M - \Delta m

\Delta = 2

3) The average amount of words per minute is:

\dot m = \frac{27}{10}

\dot m = 2.7

4) The average amount of words per minute is:

\dot M = \frac{29}{10}

\dot M = 2.9

the balance in your checking account is $962. you write checks for $39, $56 and $138. you then deposit $117 from your paycheck.
iVinArrow [24]
962-39=923   so your balance would be $846
923-56=867
867-138=729
729+117=846
