bacteria is produced in a lab. the number of bacteria, as a function of time, is modeled by y=3(2)x

your right Step-by-step explanation:

The measure of TW from the given triangle TUV is 35 units.

The point in which the three medians of the triangle intersect is known as the centroid of a triangle. It is also defined as the point of intersection of all the three medians.

Given that, in triangle TUV, Y is centroid if YW=5b and TY=4b+14.

The centroid is positioned inside a triangle. At the point of intersection (centroid), each median in a triangle is divided in the ratio of 2:1.

Now, TY/YW =2/1

(4b+14)/5b =2/1

10b=4b+14

6b=14

b=14/6

b=7/3

Now, TW=YW+TY

TW=5b+4b+14

TW=9b+14

Substitute, b=7/3 in TW=9b+14, we get

TW=9×7/3+14

= 21+14

= 35

Therefore, the measure of TW is 35 units.

Answer:

The correct answer is - 625.36.

Step-by-step explanation:

Given:

Fixed mothly plan - 616

free minutes - 150

Used minutes - 170

Free text - 150

Used text - 182

Charging amount over free limit - 18p

Solution:

Number of minutes over the limit -  170 - 150 = 20

Number of text over the limit - 182 - 150 = 32

So the extra amount that will be add to the monthly charge would be -

(20*0.18) +(32*0.18)

and the total charge of the month would be -

= 616+(20*0.18) +(32*0.18)

= 616+3.60+5.76

= 625.36

Thus, the correct answer would be - 625.36

Answer: the probability that a child is within the normal range of long growth is 0.8664

Step-by-step explanation:

Given that;

A child is considered to have a normal long growth if his or her standardized FVC is within 1.5 standard deviation of the mean.

he probability that a child is within the normal range of long growth = ?

so we need to find

P( -1.5 < z < 1.5)  

which can also be represented as;

⇒2 × ( 0 < z < 1.5)

so we have

⇒ 2 × 0.4332

= 0.8664

Therefore the probability that a child is within the normal range of long growth is 0.8664

Answer: The lorry is traveling 10 mph over the expected speed.

Step-by-step explanation:

If 200 miles takes 4 hours, the speed is 200mi/4hr which  is 50 mph.

If the distance is increased by 20%, the distance is 240 miles.

240mi/4hr = 60mph

The difference is 10mph

Answer:

Step-by-step explanation:

Answer:

(228.663 ; 241.337)

Step-by-step explanation:

Given that:

Mean (m) = 235

Standard deviation (s) = 28

α = 95%

Zcritical at 95% = 1.96

Sample size (n) = 75

The confidence interval of the population mean can be obtained using the relation :

Mean ± Error

Error = Zcritical * (s/sqrt(n))

Error = 1.96 * (28/sqrt(75))

Error = 1.96 * 3.2331615

Error = 6.33699654

Error = 6.337

Lower boundary = 235 - 6.337 = 228.663

Upper boundary = 235 + 6.337 = 241.337

(228.663 ; 241.337)

Answer:

12

Step-by-step explanation:

Hi!

We're given that the perimeter is 76. A triangle's perimeter is given by the sum of all of the sides. So, we'll find the lengths of the sides of the triangle and add them.

This is an isosceles triangle. The legs of an isosceles triangle are equal. In this problem, we're given the length of one leg: 3x-4. That means that the length of the other leg is also 3x-4. Now, the last side of the triangle is x ("base is x).

2(3x-4) + x = 76

6x-8+x=76

7x-8=76

7x=84

x=12

Let's check our answer.

3(12) - 4 =36-4 = 32

32 times 2 = 64 +12 =76

Correct!

Answer:

54 hours

Step-by-step explanation:

So, first of all subtract the money she has from the total amount.

540-60=480 She still needs $480. So divide this number by the amount she gets in an hour. (9)

480/9 =53.33333 since she can't work half hours, i rounded up.

Answer:

x=39 degrees

Step-by-step explanation:

x + 31 equals 2x - 8 because both pair of expressions must add up to 180

Answer:

x-axis = (2, -3)

y-axis = (-2, 3)

y = x (3, 2)

y= -x (-3, -2)

Step-by-step explanation:

x-axis = (2, -3) The point is below the x-axis.

y-axis = (-2, 3)  The point is left of the y-axis

y = x (3, 2) Plot the line y = x. The point is on the other side of the line.

y= -x (-3, -2) Plot the line y = -x. The point is on the other side of the line.
