Which sentence contains an inappropriate shift in tense?
Montano1993 [528]
C. Hummingbirds are hovering over the geraniums while caterpillars munched leaves.

This is because the tense of the hummingbirds is in the "ing" form, while the tense of the caterpillars is in past tense, or the "ed" form.  Because these tenses do not agree, it is an inappropriate shift in verb tense.

Beinggreat78 answer fast please :')
Dovator [93]

Answer:

17662.5 sq. feet

Step-by-step explanation:

We know that the formula for Area of a Circle is A = \pi (r)^2.

r = radius; d = diameter, which is r*2


And so, in the question, it gives you that the diameter is 150, first we divide it by 2 to get the radius.

150/2 = 75

The question said to keep \pi =3.14, so then we plug in the equation-

A = 3.14 * 75^2


Then we use PEMDAS [Parenthesis; Exponents; Multiply & Divide; Add & Subtract] which would get us-

A = 3.14 * 5625 (first doing the Exponent)

And we continue-

A = 17662.5 (then multiple)

So our answer is-

17662.5 sq. feet

I hope this helps!

If -13x-71=201 what is x
jenyasd209 [6]

Answer:

272/-13 or −20.923

Step-by-step explanation:

To solve this equation you need to isolate the variable.

First, add 71 to both sides

-13x-71+71=201+71

-13x=272

Then, divide both sides by -13

-13x/-13=272/-13

So, x=272/-13 or −20.923

A certain federal agency employs three consulting firms (A, B and C) with probabilities 0.4, 0.35 and 0.25 respectively. From pas
Marizza181 [45]

Answer:

(a) 0.29412 .

(b) No, the events selecting company A and incurring in cost overruns are not independent.

Step-by-step explanation:

We are given that a certain federal agency employs three consulting firms (A, B and C) with probabilities 0.4, 0.35 and 0.25 respectively i.e.;

 P(A) = 0.4        P(B) = 0.35          P(C) = 0.25

Also, From past experience it is known that the probability of cost overruns for the firms are 0.05, 0.03, and 0.15, respectively which means;

Let CO = Event of cost overruns

P(CO/A) = 0.05 - It means probability of cost overruns given the consulting firm involved was A.

Similarly, P(CO/B) = 0.03      P(CO/C) = 0.15

(a) Probability that the consulting firm involved is company A given a cost overrun is experienced by the company is given by, P(A/CO);

We will use Bayes' theorem here calculating the above probability ;

           P(A/CO) = \frac{P(A)*P(CO/A)}{P(A)*P(CO/A) + P(B)*P(CO/B) + P(C)*P(CO/C)}

                          = \frac{0.4*0.05}{0.4*0.05 + 0.35*0.03 + 0.25*0.15} = 0.29412 .

(b) No, the events selecting company A and incurring in cost overruns are not independent because the cost overruns happens only when the consulting firm is involved and also the cost overruns will differ as we move towards another consulting firm so the chances of cost overruns will depend on the fact that which consulting firm has been involved.
