What are the solutions to the quadratic equation (5y +6) 2= 24?

boyakko [2]

Answer:

$y=-2.18,-0.22$

Step-by-step explanation:

We have been given the equation

$(5y+6)^2=24$

Take square root both sides. When ever we take square root, we include plus minus sign

$\sqrt{(5y+6)^2}=\pm\sqrt{24}\\\\5y+6=\pm2\sqrt6$

Now, subtract 6 to both sides of the equation

$5y=-6\pm2\sqrt6$

Divide both sides by 5

$y=\frac{1}{5}(-6\pm2\sqrt6)$

$y=\frac{1}{5}(-6+2\sqrt6),y=\frac{1}{5}(-6-2\sqrt6)$

In decimal we have

$y=-2.18,-0.22$

Fifteen people have been exposed to a particular disease. Each one independently has a 40% chance of contracting the disease. A

valina [46]

Answer: e. .0950

Step-by-step explanation:

Let X be the number of people that can be cure from disease.

Since each people independently has a 40% chance of contracting the disease.

So , $X\sim Binomial(n=15,p=0.40)$

A hospital has the capacity to handle at most 8 cases of the disease.

Binomial distribution formula : $P(X=x)= ^nC_xp^x(1-p)^{n-x}$

Then , the probability that the hospital’s capacity will be exceeded

$P(X>8)=1-P(X\leq8)\\\\=1-0.905\ \ [\text{Using Binomial distribution table for n=15 , x=8 and p=0.4.}]$

$=0.095$

Hence, the probability that the hospital’s capacity will be exceeded is e. .0950.

Thus , the correct option is e. .0950.

A metal pipe is 1.4 m long. Its internal diameter is 25 mm and thickness 1 mm. If 1 mm³ of the metal weighs 0.02 gm, find the we

<h3>What is Unit of Measurement?</h3>

It is definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

It is given,

A metal pipe is 1.4 m long

Length of metal pipe is 1.4m=1400mm

Its internal diameter is 25 mm

Radius =12.5mm

Thickness=1mm

outer radius=12.5+1=13.5mm

volume of pipe=

V=π(R²−r² )h

V=3.142(13.5²-12.5²)1400

V=3.142(182.25-156.25)1400

V=3.142(26)1400

V=114368.8

1 mm³ of the metal weighs 0.02 gm

So 1.4 m long metal weights 114368.8×0.02=2287.4gm

Hence, the weight of the pipe is 2287.4gm.
