The sum of three consecutive integers is −387. Find the three integers.
rjkz [21]

Answer: -130, - 129, - 128

Step-by-step explanation:

x + x+1 + x+2 = - 387

3x + 3 = - 387

3x = - 387 - 3

x = - 390/3

x = - 130

Find the circumference given the area = 113.1 ft². Use 3.14 for π as necessary.
olga_2 [115]

The circumference of the circle is 37.68 ft

Step-by-step explanation:

Given,

The area of the circle is 113.1 sq ft

To find the circumference of the circle we need to find the radius of the circle first

Formula

The area of circle with radius r is = πr^{2} sq unit

The circumference of circle with radius r is = 2πr unit

Let us take the radius of the circle is r ft

According to the problem,

πr^{2} =113.1

or, r^{2} = \frac{113.1}{3.14}

or, r^{2} = 36.01 = 36 (approx)

or, r = \sqrt{36}

or, r = 6

Now,

The circumference of the circle is 2×3.14×6 ft = 37.68 ft

Chocolate chip cookies have a distribution that is approximately normal with a mean of 24.2 chocolate chips per cookie and a sta
Allisa [31]

Answer:

Percentile 5

z=-1.64

And if we solve for a we got

a=24.2 -1.64*2.6=19.94

Percentile 95

z=1.64

And if we solve for a we got

a=24.2 +1.64*2.6=28.46

Step-by-step explanation:

Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:

X \sim N(24.2,2.6)  

Where \mu=24.2 and \sigma=2.6

We want to find the percentiles 5 and 95 for this case.

Percentile 5

For this part we want to find a value a, such that we satisfy this condition:

P(X>a)=0.95   (a)

P(X   (b)

We want to find a percentile with 0.95 of the area on the left and 0.05 of the area on the right it's z=-1.64. On this case P(Z<-1.64)=0.05 and P(z>-1.64)=0.05

Using this condition we got:

P(X  

P(z

Replacing we got:

z=-1.64

And if we solve for a we got

a=24.2 -1.64*2.6=19.94

Percentile 95

z=1.64

And if we solve for a we got

a=24.2 +1.64*2.6=28.46
