3x + 5y = 30

Mathematics
1 answer:
GrogVix [38]3 years ago
3 0

Answer:

y= - \frac{3x}{5}  + 6

Step-by-step explanation:

The given linear equation is

3x + 5y = 30

To solve for y, we first subtract 3x from both sides to obtain:

5y = 30 - 3x

Divide through by 5

\frac{5y}{5}  =  \frac{30}{5}  -  \frac{3x}{5}

This simplifies to

y= 6-  \frac{3x}{5}

Or

y= - \frac{3x}{5}  + 6

The given values are discrete. Use the continuity correction and describe the region of the normal distribution that corresponds
Lerok [7]

Answer:

P_B(X\leq35)=P_N(X

Step-by-step explanation:

If we approximate the binomial distribution with a normal distribution, we have to apply a correction factor for the fact that we are now dealing with a continuous variable instead of a discrete one, as it was with the binomial distribution.

The probability of no more than 35 defective CDs: P(X<35)

In this case, as X=35 is not included in the interval, we start the interval from X=35-0.5=34.5.

P_B(X\leq35)=P_N(X

being Pb the probability under the binomial distribution and Pn the probability under the normal distribution.

The area for the normal distribution is the one below X=34 (or P(X<34)).

(11-8)x3+7+27-3<br> (18÷3)+6+(14-8)x5<br> (11-7)x6+4+32-4
horsena [70]

The results of the arithmetic evaluations as given in the task content are; 40,42 and 62.

<h3>What are the results of the arithmetic evaluations?</h3>

The arithmetic operations above can be evaluated and simplified as follows;

(11-8)x3+7+27-3 = (3×3)+7+27-3 = 40.

(18÷3)+6+(14-8)x5 = (6)+6+(6)x5 = 42.

(11-7)x6+4+32-4 = (5×6) +4 +32-4 = 62.

What is thr inverse of f(x) if the function is x=-4,-2,0,2,4 f(x)=-2,-1,0,1,2
Lorico [155]
For a function, if it has an inverse function, keep in mind that, the "domain of the original, is the range of the inverse, and the range of the original, is the domain of the inverse", what the dickens does that mean?

well, it means the values for "x" and f(x), on the inverse, are the same values, but swapped up, therefore

\bf \stackrel{original~function}{\begin{array}{ccll}&#10;x&f(x)\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;-4&-2\\&#10;-2&-1\\&#10;0&0\\&#10;2&1\\&#10;4&2&#10;\end{array}}\qquad \qquad \qquad &#10;\stackrel{inverse~function}{\begin{array}{ccll}&#10;x&f(x)\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;-2&-4\\&#10;-1&-2\\&#10;0&0\\&#10;1&2\\&#10;2&4&#10;\end{array}}

There are 45 red tiles,25 blue tiles and 30 green tiles in a bag.
Mazyrski [523]
This is a question of probability.
Probability of picking any color= number of tiles with that color/total number of tiles
Total=45+25+30=100
P(red tile)=(45/100)x60=0.45x60=27
P(blue tile)=(25/100)x60=0.25x60=15
P(green tiles)=(30/100)x60=0.3x60=18
