Answer:

y=-2

Step-by-step explanation:

in other words, the question is asking

"six time what plus four equals 12?"

we know that 6 ⋅ 2 = 12

therefore if we plug the -2 into the Y we get

6(-2+4)=12

6(2)=12 or 6⋅2=12

therefore the answer is y=-2

A company makes three sizes of juice bottles: small, medium, and large.

Ivahew [28]

An expression in terms of s that represents the number of large bottles is : L = $(\frac{15s}{2} /3})$

<h3>Ratio of different sizes of bottles </h3>

The company makes s small bottles every minute

let ; M represent the number of medium bottles made every minute

L represent the number of large bottles made every minute

small bottles to medium = 2 : 3

small bottles to medium = s : M

M is the unknown, so to find how many medium bottles that has been made, we must cross multiply

2M = 3s

M = $\frac{3s}{2}$ medium bottles made every minute

medium bottles to large bottles = 3 : 5

medium bottles to large bottles = M : L

where M = $\frac{3s}{2}$

The equation becomes:

3 : 5

$\frac{3s}{2}$ : L

L is the unknown, so to find how many Large bottles that has been made, we must cross multiply

3L =( $\frac{3s}{2}$ ) * 5

L = $(\frac{15s}{2} /3})$

L = ( $\frac{5}{2}$ s)

L = 2.5 s

therefore the large bottles the company makes every minute is 2.5s large bottles

we can conclude that the expression for the number of large bottles the company makes every minute with respect to s is : L = 2.5 s

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 141 millimeters,

tiny-mole [99]

Answer:

Probability that the sample mean would be greater than 141.4 millimetres is 0.3594.

Step-by-step explanation:

We are given that Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 141 millimetres, and a standard deviation of 7.

A random sample of 39 steel bolts is selected.

Let $\bar X$ = <u><em>sample mean diameter</em></u>

The z score probability distribution for sample mean is given by;

Z = $\frac{ \bar X-\mu}{\frac{\sigma}{\sqrt{n} } } }$ ~ N(0,1)

where, $\mu$ = population mean diameter = 141 millimetres

$\sigma$ = standard deviation = 7 millimetres

n = sample of steel bolts = 39

Now, Percentage the sample mean would be greater than 141.4 millimetres is given by = P( $\bar X$ > 141.4 millimetres)

P( $\bar X$ > 141.4) = P( $\frac{ \bar X-\mu}{\frac{\sigma}{\sqrt{n} } } }$ > $\frac{141.4-141}{\frac{7}{\sqrt{39} } } }$ ) = P(Z > 0.36) = 1 - P(Z $\leq$ 0.36)

= 1 - 0.6406 = <u>0.3594</u>

The above probability is calculated by looking at the value of x = 0.36 in the z table which has an area of 0.6406.
