Step-by-step explanation:

HAVE A GOOD DAY!

The expression (9.6 × 10³) × (6.7 × 10²) can be simplified in scientific notation as  6.432 × 10⁶ , 64.32 × 10⁵ and (9.6 × 6.7) × (10³ × 10²) .

Scientific notation is a means to express values that are either too big or too little to be conveniently stated in decimal form (typically would result in a long string of digits). It is also known as standard form in the UK and scientific form, standard index form, and standard form. Scientists, mathematicians, and engineers frequently utilize this base ten notation because it can make some mathematical operations simpler.

The given expression is : (9.6 × 10³) × (6.7 × 10²)

First we multiply the decimal terms separately.

So  (9.6 × 6.7) = 64.32 and now we multiply the power terms

10³ × 10² = 10²⁺³ = 10⁵ ( By using the properties of exponents)

So in proper scientific notation 64.32 × 10⁵ = 6.432 × 10⁶

Which can also be written as 6.432 × 10⁶ or (9.6 × 6.7) × (10³ × 10²) .

Answer:

-4

Step-by-step explanation:

y=-4x-9

y=mx+b

m=slope

Hello, hope you are having a splendid day. :)

y=-4x-9 is written in slope-intercept form (y=mx+b)

m is the slope and b is the y-intercept.

In this equation, the slope is -4 and the y-intercept is -9.

Hope it helps. Ask me if you have any queries.

Answer:

The numbers 'x' and 'y' are:

[tex]x=56,\:y=36[/tex]

Step-by-step explanation:

Let 'x' and 'y' be the two numbers

As the sum of the two numbers is 92.

so

[tex]x+y = 92[/tex]

Given that One-eighth of the larger number plus one-third of the smaller number is 19.

so

[tex]\frac{1}{8}x\:+\:\frac{1}{3}y=19[/tex]

now solving both equations to determine the numbers 'x' and 'y'.

[tex]\begin{bmatrix}\frac{1}{8}x+\frac{1}{3}y=19\\ x+y=92\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}\frac{1}{8}x+\frac{1}{3}y=19\mathrm{\:by\:}8\:\mathrm{:}\:\quad \:x+\frac{8}{3}y=152[/tex]

[tex]\begin{bmatrix}x+\frac{8}{3}y=152\\ x+y=92\end{bmatrix}[/tex]

[tex]x+y=92[/tex]

[tex]-[/tex]

[tex]\underline{x+\frac{8}{3}y=152}[/tex]

[tex]-\frac{5}{3}y=-60[/tex]

[tex]\begin{bmatrix}x+\frac{8}{3}y=152\\ -\frac{5}{3}y=-60\end{bmatrix}[/tex]

solve for y

[tex]-\frac{5}{3}y=-60[/tex]

[tex]-5y=-180[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}-5[/tex]

[tex]\frac{-5y}{-5}=\frac{-180}{-5}[/tex]

[tex]y=36[/tex]

[tex]\mathrm{For\:}x+\frac{8}{3}y=152\mathrm{\:plug\:in\:}y=36[/tex]

[tex]x+\frac{8}{3}\cdot \:36=152[/tex]

[tex]x=56[/tex]

Thus, the numbers 'x' and 'y' are:

[tex]x=56,\:y=36[/tex]

Answer:

The price of the coat after the second discount is applied is $42.35.

Step-by-step explanation:

First, you need to find the amount after the first discount by multiplying the original price by 45% and subtracting that amount from the initial price:

$110*45%=$49.5

$110-$49.5=$60.5

Now, you have to find the price of the coat after the second discount by calculating 30% of the price after the first discount and subtracting the result from that price:

$60.5*30%=$18.15

$60.5-$18.15=$42.35

According to this, the answer is that the price of the coat after the second discount is applied is $42.35.

Answer: just graph them

Step-by-step explanation: the month is on the x axis and the money/people is in the y axis.

Answer:

7/9=28/y

We move all terms to the left:

7/9-(28/y)=0

Domain of the equation: y)!=0

y!=0/1

y!=0

y∈R

We add all the numbers together, and all the variables

-(+28/y)+7/9=0

We get rid of parentheses

-28/y+7/9=0

We calculate fractions

The required answer is  y = 36 is the value that makes the equation true.

Given that 7 divided by 9=28 divided by y

A proportion is an equation that relates two ratios or fractions, stating that they are equal. It can be used to solve problems involving ratios or to find an unknown value.

To solve a proportion, we use the concept of cross-multiplication. This involves multiplying the numerator of one fraction by the denominator of the other fraction and setting the two products equal to each other.

To find the value of y in the equation 7 divided by 9 = 28 divided by y, set up a proportion and solve for y.

The proportion can be written as:

7 / 9 = 28 / y

To solve for y, by cross-multiplication:

7 x y = 9 x 28

Simplifying:

7y = 252

Dividing both sides of the equation by 7:

y = 252 / 7

y = 36

Therefore, the value of y that satisfies the equation 7 divided by 9 = 28 divided by y is y = 36.

Substitute y = 36 into the equation, gives:

7 / 9 = 28 / 36

After simplifying both sides of the equation, we find that both fractions are equal to 4/9.

Hence, y = 36 is the value that makes the equation true.

Answer:

Step-by-step explanation:

The first thing I notice is the slope, which is going down, which means this is for sure a negative slope. So any slopes that just include 5 is now crossed off.  And since the formula goes like y=mx+b, I believe the answer would be C, because it actually follows the formula as it should.

Mariah and Clarence are planning for a dinner party. The grocery store is selling a 25- pound turkey for $60 . Mariah states, "that means it costs $2.40 per pound of turkey." Clarence states, "that means $2.4 pounds of turkey cost $1 Is Mariah's statement, Clarence's statement, both statements, or neither statement correct?

Answer:

Mariah's statement is correct

Step-by-step explanation:

Mariah and Clarence are planning for a dinner party. The grocery store is selling a 25- pound turkey for $60 .

From the statements given above, we are to find the unit rate . This means the cost of the turkey per pound

Hence, the calculation is given below:

25 pounds of turkey = $60

1 pound of turkey = x

Cross Multiply

25 × x = $60 × 1

x = $60/25

x = $2.40

1 pound of turkey cost $2.40

Therefore, Mariah's statement is correct

Binomial distribution = 0.1026

Normal approximation = 0.1066

Step-by-step explanation:

Given that :

p = 100% - 7% = 0.93

n = 300

1 - p = 0.07

Probability of atleast 285 rooms getting booked :

P(x = x) = nCx * p^x * (1-p)^(n-x)

To obtain P(x ≥ 285) ; we use a binomial probability calculator to save time :

P(x ≥ 285) = 0.1026

Using Normal approximation :

Mean (m) = np = 300 * 0.93 = 279

Standard deviation (s) = sqrt(np(1-p) = sqrt(285*0.07) = 4.419 = 4.42

Using :

Z = (x - m) / s

P(x ≥ 285) ; for normal approximation :P(x ≥ x) x = 285 - 0. 5 = 284.5

Z = (284.5 - 279) / 4.42

= 1.2443

P(Z ≥ 1.2443) = 0.1066 (Z probability calculator)
