So for 1: You divide 1780 by 36 to get your answer. You will get a remainder but in this situation, we ignore it since you wouldn’t be able to wrap another gift completely

2: Divide 247 by 52. Again, you will get a remainder but in this situation we found up to the nearest whole because to be able to take all the kids, you would need another bus.

3: Divide 98 by 28. You will get a remainder, then you take that and divide it by 28, and simplify it, to get the fraction

Answer:

The correct answer is A) $7.00

Step-by-step explanation:

In order to determine that, you can use any two points and the slope formula. For the purpose of this, we'll use (1, 39) and (3, 53)

m(slope) = (y2 - y1)/(x2 - x1)

m = (53 - 39)/(3 - 1)

m = 14/2

m = 7

The lengths of human pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. What is t

AfilCa [17]

Answer: A. 0.0164

Step-by-step explanation:

Given : The lengths of human pregnancies are normally distributed with a mean $\mu=268\text{ days}$

Standard deviation : $\sigma=15\text{ days}$

Let X be the random variable that represents the length of pregnancy of a randomly selected human .

z-score : $z=\dfrac{X-\mu}{\sigma}$

For X = 300

$z=\dfrac{300-268}{15}\approx2.13$

Now, the probability that a pregnancy last at least 300 days will be :-

$P(X\geq300)=P(z\geq 2.1333)=1-P(z$

Hence, the probability that a pregnancy last at least 300 days =0.0164

The length of a rectangle is 7 meters longer that it’s width. What is the width of this rectangle if it’s perimeter is equal to

dolphi86 [110]

The width of rectangle is 21 meters.

Step-by-step explanation:

Given,

Perimeter of rectangle = 98 meters

Width of rectangle = w

Length of rectangle = w+7

Perimeter of rectangle = 2(Length+Width)

Perimeter = $2(w+7+w)$

$98=2(2w+7)\\98=4w+14\\98-14=4w\\84=4w\\4w=84$

Dividing both sides by 4

$\frac{4w}{4}=\frac{84}{4}\\w=21$

Width of rectangle = 21 meters

The width of rectangle is 21 meters.
