The temperature at noon is equal to -0.1°C.

Mathematically, the standard form or slope-intercept form of the equation of a straight line is given by this mathematical expression;

y = mx + c

Where:

Note: Let x represent the time.

Next, we would write an equation that models the situation based on the rate of change (slope) and y-intercept (initial value) as follows;

y = mx + c

y = -0.8x - 2.5

y = -0.8(3) - 2.5

Answer:

[tex]\displaystyle{f(x)=x^4 \ \: \text{and} \ \: a =2}[/tex]

Step-by-step explanation:

The first principal of derivative:

[tex]\displaystyle{f'(x) = \lim_{h\to 0} \dfrac{f(x+h)-f(x)}{h}}[/tex]

Since the given problem represents f'(a), meaning:

[tex]\displaystyle{f'(a) = \lim_{h\to 0} \dfrac{f(a+h)-f(a)}{h}}[/tex]

If we compare:

[tex]\displaystyle{f'(a) = \lim_{h\to 0} \dfrac{f(a+h)-f(a)}{h}}[/tex]

and

[tex]\displaystyle{ \lim_{h\to 0} \dfrac{(2+h)^4-16}{h}}[/tex]

which can be rewriten as:
[tex]\displaystyle{f'(a) = \lim_{h\to 0} \dfrac{(2+h)^4-2^4}{h}}[/tex]

We can conclude by comparing that:

This would mean that:

The length of the train can be calculated using the formula:

Length of the train = Speed x Time / 2

Where,

Speed = 60 km/hr = 60 x 1000/60 = 1000 m/min

Time = 9 sec = 9 / 60 min = 0.15 min

So,

Length of the train = 1000 x 0.15 / 2 = 75 m

Therefore, the length of the train is 75 meters.

The total amount spent on tickets by Edgar is $15.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Let x be the cost of one game ticket and y be the cost of one ride ticket.

From the table, we can form two linear equations regarding the total amount spent by Erica and Penny.

10x + 5y = 10

15x + 10y = 16.25

Multiplying the first equation throughout with 2,

20x + 10y = 20

Subtracting 15x + 10y = 16.25 from the above equation,

(20x + 10y) - (15x + 10y) = 20 - 16.25

5x = 3.75

x = 0.75

Substituting x = 0.75 in 10x + 5y = 10,

7.5 + 5y = 10

5y = 2.5

y = 0.5

Cost of a game ticket is $0.75 and cost of a ride ticket is $0.50.

Total cost by Edgar = (12 × 0.75) + (12 × 0.5) = $15

Hence the total money spent by Edgar for both game and ride tickets is $15.

The amount that will be in the account in 25 years is $16,282.298.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

Given that,

Principal amount, P = $3000

Rate of interest, r = 7% = 0.07

Answer:

The number with the highest sum of prime factors is 27, as it has only two prime factors: 3 and 3. The sum of its prime factors is 6, so if you choose 27, you can move 6 spaces. The number 25 has two prime factors as well, but only 5 + 5 = 10. 26 is not a prime number, so it wouldn't be the best choice. So, if you want to move as many spaces as possible, you should choose 27.

Let "w" the number of weeks they collected the pictures

For Yuki,

The total picture he has after 0 weeks = is 20

The total picture he has after 1 week = 20 + 60

The total picture he has after 2 weeks = 20 + 60*2

The total picture he has after w weeks = 20 + 60*w

For Roman,

The total picture he has after 0 weeks = is 110

The total picture he has after 1 week = 110 + 35

The total picture he has after 2 weeks =110 + 35*2

The probability that the mean of a sample of 40 families will be between 17.1 and 18.1 pounds is given as follows:

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The parameters for this problem are given as follows:

[tex]\mu = 17.2, \sigma = 2.5, n = 40, s = \frac{2.5}{\sqrt{40}} = 0.3953[/tex]

The probability that the mean of a sample of 40 families will be between 17.1 and 18.1 pounds is the p-value of Z when X = 18.1 subtracted by the p-value of Z when X = 17.1, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (18.1 - 17.2)/0.3953

Z = 2.28

Z = 2.28 has a p-value of 0.9887.

Z = (17.1 - 17.2)/0.3953

Z = -0.25

Z = -0.25 has a p-value of 0.4013.

The arena should be financed by selling $  320   million in bonds and borrowing $  480   million.

==========================================================

Work Shown:

Something like x = 27 means "27 million dollars of bonds were sold".

The variable x has the restriction of [tex]0 \le x \le 480[/tex] since $480 million is the ceiling for the bonds.

The variable y has the restriction of [tex]0 \le y \le 640[/tex] since $640 million is the ceiling for the money borrowed from the insurance company.

The two amounts, x and y, must add to 800 to represent the $800 million total that needs to be raised.

x+y = 800

y = 800-x

-------------------

Let's calculate the interest for each item. Use the simple interest formula.

Bonds at 7% interest rate:

i = P*r*t

i = x*0.07*1

i = 0.07x

Borrowed money at 2% interest rate:

i = P*r*t

i = y*0.02*1

i = 0.02y

Total annual interest = 0.07x+0.02y = 32

The 32 at the end represents the $32 million of interest payout. This amount of money is paid to the bondholders and to the insurance company, and is done so yearly.

-------------------

Apply substitution to solve for x.

0.07x+0.02y = 32

0.07x+0.02(800-x) = 32 ...... plug in y = 800-x

0.07x+16-0.02x = 32

0.05x+16 = 32

0.05x = 32-16

0.05x = 16

x = 16/(0.05)

x = 320

They should sell $320 million in bonds.

320 million = 320,000,000

Note how x = 320 is in the interval [tex]0 \le x \le 480[/tex]

y = 800-x

y = 800-320

y = 480

They should borrow $480 million at an interest rate of 2%

480 million = 480,000,000

Note how y = 480 is in the interval [tex]0 \le y \le 640[/tex]

Answer:

The arena should be financed by selling $320 million in bonds and borrowing $480 million.

Step-by-step explanation:

Simple interest is calculated by multiplying the principal by the interest rate (in decimal form) and the time (in years).

Let x be the amount raised by selling bonds that pay an annual simple interest rate of 7%.

Therefore:

As the total cost of the sports arena is $800 million, the amount raised from borrowing money from the insurance company at an annual simple interest rate of 2% is (800 - x).  Therefore:

To determine whether the arena can be financed so that the annual interest is $32 million, equate the sum of the two expressions for interest to 32 and solve for x:

[tex]\implies 0.07x+0.02(800-x)=32[/tex]

[tex]\implies 0.07x+16-0.02x=32[/tex]

[tex]\implies 0.05x+16=32[/tex]

[tex]\implies 0.05x=16[/tex]

[tex]\implies x=320[/tex]

As x is the amount raised by selling bonds, then the amount in bonds that should be sold is $320 million.

To calculate the amount to borrow, subtract the amount in bonds sold from $800 million:

[tex]\implies 800-320=480[/tex]

Therefore, the amount to be borrowed from an insurance company is $480 million.

As both these amounts are less than the maximum limits set, they are both valid.

Probability theory is an area of mathematics that focuses on calculating the probability that a claim is accurate or that a particular occurrence will occur. Chance can be represented by any number range between 0 and 1, where 1 often denotes certainty and 0 typically denotes possibility. A probability diagram shows the possibility that a specific event will occur. The numerals 0 and 1, fractions with a ranging of 0% to 100%, or a few more characters can all be used to indicate probabilities.

Here,

Given that we've done it

Amount of CDs: 2100

50 faulty CDs total.

If every component of the sample is acceptable, the complete batch is accepted.

Therefore, we shall apply the "Binomial Theorem"

If there is no flaw, let p be the likelihood of success.

So, => p = 2100 - 50 / 2100

=> p = 2050/2100

=> p =0.97

q is the likelihood of a failure, or defect.

So,

=> q = 50/2100

=> q = 0.02

hence, the number of CDs chosen is 6.

Consequently, it is => P(X=6) = (0.97)6 = 0.832.

The likelihood that the full batch will be approved is therefore 0.832.
