Does anyone know what 8x1/6 is?

Answer:

y= -11/144(x-8)^2+6

Step-by-step explanation:

This equation can be represented in vertex form, which is:  

y=a(x-h)^2+k

If we plug in 8 as h and 6 as k we get the following equation:

y=a(x-8)^2+6

Now we have to plug in x and y. We can use the other point (-4,-5) and plug it into the equation and get:

-5=a(-4-8)^2+6

Once we solve this we get a= -11/144

Now we have to plug in -11/144 into the original equation to get

y = -11/144 (x-8)^2 + 6

The 36% of the students in the sample prefer cats. Hence, 36% is correct answer.

The step-by-step calculation to determine what percent of students in  sample prefer cats:
1) Find the total number of students who prefer cats:

Add the number of male students who prefer cats (10) to the number of female students who prefer cats (26). 10 + 26 = 36
2) Find the total number of students surveyed:

Add the number of students who prefer dogs (36 + 20), the number of students who prefer cats (36), and the number of students with no preference (2 + 6). 36 + 20 + 36 + 2 + 6 = 100
3) Calculate the percentage of students who prefer cats:

Divide number of students who prefer cats (36) by the total number of students surveyed (100) and multiply by 100%. 36 / 100 * 100% = 36%
4) Round the answer to the nearest percent:

36% rounded to nearest percent is 36%.

Complete and correct question is in the image:

According to the given sample, 36% of students in the sample prefer cats.

To find the percentage of students in the sample who prefer cats, we need to sum up the number of students who prefer cats, which is 26 for females and 10 for males.

Total number of students who prefer cats = 26 (females) + 10 (males) = 36.

Now, let's find the total number of students in the sample:

Total number of students = 36 (males who prefer dogs) + 20 (females who prefer dogs) + 10 (males who prefer cats) + 26 (females who prefer cats) + 2 (males with no preference) + 6 (females with no preference)

= 36 + 20 + 10 + 26 + 2 + 6

= 100.

Now, we can calculate the percentage of students who prefer cats:

Percentage of students who prefer cats = [tex]\frac{Number \ of \ students \ who \ prefer \ cats}{Total \ number \ of \ students}[/tex] × 100

= ([tex]\frac{36}{100}[/tex]) × 100 = 36%.

So, approximately 36% of students in the sample prefer cats.

The question is:

Students were surveyed about their preference between dogs and cats. The following two-way table displays data for the sample of students who responded to the survey.

Preference  Male  Female

Prefers dogs  36  20

Prefers cats  10  26

No preference  2  6

Answer: 17 containers

Step-by-step explanation:

Debbie bought 8 1/2 lb of ground turkey and she packed the turkey in 1/2 lb containers before put the turkeys in the freezer.

To calculate the number of containers she used for packing the turkey, we divide 8 1/2lb by 1/2 lb.

= 8 1/2 ÷ 1/2

We change 8 1/2 to improper fraction

= 17/2 ÷ 1/2

= 17/2 × 2/1

= 17

Debbie would need 17 containers to pack the turkey.

Answer:

Answer:

The value of Rebecca's investment equals the value of Hector's investment after approximately 15.8 years to the nearest tenth

The common value of the investments is approximately $2358.05

Step-by-step explanation:

The formula of the compound interest including the principal is

[tex]A=P(1+\frac{r}{n})^{nt}[/tex] , where

Hector invests $800 in an account that earns 6.96% annual interest compounded semiannually

∵ P = 800

∵ r = 6.96 = [tex]\frac{6.96}{100}[/tex] = 0.0696

∵ n = 2 ⇒ semiannually

- Substitute all these values in the formula to find future value

∴ [tex]A=800(1+\frac{0.0696}{2})^{2t}[/tex]

∴ [tex]A=800(1.0348)^{2t}[/tex]

Rebecca invests $1,000 in an account that earns 5.44% annual interest compounded monthly  

∵ P = 1,000

∵ r = 5.44 = [tex]\frac{5.44}{100}[/tex] = 0.0544

∵ n = 12 ⇒ monthly

- Substitute all these values in the formula to find future value

∴ [tex]A=1000(1+\frac{0.0544}{12})^{12t}[/tex]

∴ [tex]A=1000(1.004533333)^{12t}[/tex]

∵ Rebecca's investment equals the value of Hector's investment

- Equate the two equations

∵  [tex]1000(1.004533333)^{12t}[/tex] = [tex]800(1.0348)^{2t}[/tex]

- Insert ㏑ in both sides and remember ㏑(ab) = ㏑(a) + ㏑(b)

∴ ㏑( [tex]1000(1.004533333)^{12t}[/tex] ) = ㏑( [tex]800(1.0348)^{2t}[/tex] )

∴ ㏑(1000) + ㏑( [tex](1.004533333)^{12t}[/tex] ) = ㏑(800) + ㏑( [tex](1.0348)^{2t}[/tex] )

- Remember [tex]ln(a)^{n}[/tex] = n ㏑(a)

∴ ㏑(1000) + 12t [㏑(1.004533333)] = ㏑(800) + 2t [㏑(1.0348)]

- Subtract ㏑(800) and 12t [㏑(1.004533333)] from both sides

∴ ㏑(1000) - ㏑(800) = 2t [㏑(1.0348)] - 12t [㏑(1.004533333)]

- Take t as a common factor from the right hand side

∴ ㏑(1000) - ㏑(800) = t(2[㏑(1.0348)] - 12[㏑(1.004533333)])

- Divide both sides by (2[㏑(1.0348)] - 12[㏑(1.004533333)])

∴ 15.8 = t

The value of Rebecca's investment equals the value of Hector's investment after approximately 15.8 years to the nearest tenth

Let us find this value using Hector or Rebecca equations

∵  [tex]A=800(1.0348)^{2t}[/tex]

- Substitute t by 15.8

∴  [tex]A=800(1.0348)^{2(15.8)}[/tex]

∴ A = 2358.05

The common value of the investments is approximately $2358.05

probability of the red car = 25/65

to the lowest form is the 5/13(D)

Answer:

its D

Step-by-step explanation:

"The correct answer is C. The statement If these probabilities are correct, 12%is the probability that it will rain both days

To find the probability that it will rain both days, we need to multiply the probability of rain on Saturday by the probability of rain on Sunday, assuming that the events are independent.

The probability of rain on Saturday is 30%, which can be expressed as 0.30 or[tex]\(\frac{30}{100}\)[/tex].

The probability of rain on Sunday is 40%, which can be expressed as 0.40 or[tex]\(\frac{40}{100}\)[/tex].

Now, we multiply these two probabilities to find the probability of both events occurring:

[tex]\[ P(\text{Rain on Saturday}) \times P(\text{Rain on Sunday}) = \frac{30}{100} \times \frac{40}{100} \][/tex]

[tex]\[ \frac{30}{100} \times \frac{40}{100} = \frac{30 \times 40}{100 \times 100} \] \[ \frac{30 \times 40}{100 \times 100} = \frac{1200}{10000} \] \[ \frac{1200}{10000} = \frac{12}{100} \] \[ \frac{12}{100} = 0.12 \][/tex]

Converting this decimal to a percentage, we get 12%.

Therefore, the probability that it will rain both days is 12%."

Option B. 1024(0.5)^x

Step-by-step explanation:

From the question given, we were told that half (1/2) the players are eliminated at the end of each round.

If T is the total number players, then after round one it becomes:

T x (1/2)^1 = T x 0.5

After round x, the the numbers of player remaining will be:

T x (1/2)^x = T x (0.5)^x

From the question given, the total number of players are 1024. Therefore, the above expression can be written as:

T x (0.5)^x => 1024(0.5)^x

Answer:

The horizontal shift from point A to point A’ is -2. The vertical shift from point A to  point A’ is 5. Since in a translation all points shift the same distance, the coordinates of  point B’ are (5, 7 ).

Step-by-step explanation:

A moved two units to the left.

1 - 3 = -2

A also moved 5 units up.

12 - 7 = 5

The translation rule is: [tex](x,y) -> (x - 2, y + 5)[/tex]

Apply the translation rule to point B.

[tex](7 -2, 2+5) = (5,7)[/tex]

B' should be (5,7).

Answers and Step-by-step explanations:

1. The horizontal shift from point A to point A' will simply be the difference in the x-coordinates. The x-coordinate of A is 3 and the x-coordinate of A' is 1. So, we take 1 - 3 = -2. The horizontal shift is 2 units to the left.

2. The vertical shift is the difference in the y-coordinates. The y-coordinate of A is 7 and the y-coordinate of A' is 12. So, we take 12 - 7 = 5. The vertical shift is 5 units up.

3. Basically, we want to move the coordinates of B 2 units to the left and 5 units up. B is currently (7, 2). When we move 2 units to the left, we subtract 2 from the x-coordinate 7, and when we move 5 units up, we add 5 to the y-coordinate 2: B' = (7 - 2, 2 + 5) = (5, 7)

After 21.28  minutes will the coffee be only lukewarm (30∘C)

Step-by-step explanation:

Given -

A travel mug of 87∘C coffee is left on the roof of a parked car on a cold winter day . The temperature of the coffee after t minutes is given by

                 [tex]H = 87(2)^{\frac{-t}{14}}[/tex]

Let after [tex]t_{1}[/tex] time  H will be [tex]$30^\circ$[/tex]C

put t = [tex]t_{1}[/tex]  ,  H = [tex]$30^\circ$[/tex]C

       [tex]30 = 87(2)^{\frac{-t_{1}}{14}}[/tex]

       [tex]\frac{30}{87} = (2)^{\frac{-t_{1}}{14}}[/tex]

      .3448275 = [tex](2)^{\frac{-t_{1}}{14}}[/tex]

     Taking logarithm both side  

     [ [tex]log(2^{x}) = xlog2[/tex] ]

      log.3448275 = [tex]{\frac{-t_{1}}{14}}[/tex] log 2

      -.4581  =  [tex]{\frac{-t_{1}}{14}} \times.3010[/tex]

       [tex]{\frac{-t_{1}}{14}}[/tex]  =  -1.52

       [tex]t_{1}[/tex] = 21.28 minutes

To find the time it will take for the coffee to cool to 30 degrees Celsius, we need to solve the equation 30=87(2)−t/14 for the variable 't', which represents time.

The subject of this problem is a mathematical application of heat transfer. To answer this question thoroughly, we need to solve the given equation H=87(2)−t/14 for 't' when H (the temperature of the coffee) is 30 degrees Celsius.

When we set H equal to 30, we can rearrange the equation to solve for 't':

While this equation primarily pertains to heat transfer, it is also fundamentally about solving algebraic expressions, the core focus of high school Mathematics.

Answer: shameeka sold 20 hamsters to the store.

Step-by-step explanation:

Let x represent the number of hamsters that shameeka sold to the store.

Let y represent the number of hamsters that the pet store had initially.

Shameeka sold her hamsters to a pet store. This doubled the number of hamsters in the store. It means that

x + y = 2y

x = 2y - y

x = y

Then the store got six more hamsters. If the pet store has 46 hamsters now, it means that

2y + 6 = 46

2y = 46 - 6

2y = 40

y = 40/2

y = 20

Since x = y, then

x = 20

Answer:

T = sin(6572t)

Step-by-step explanation:

A pure tone is a sine-wave and sine-waves are defined by ω (omega) and t (time)

For a sine model:

Amplitude of wave form = sin(ωt)

A sine model that gives the Tone, T, as a function of time, t, for this key:

T = sin(ωt)

Sin is a mathematical operator in trigonometry

ω = 2πf

π = 3.14

The frequency of the 64th key on a standard 88-key piano is 1046.5 hertz.

f = 1046.5 hertz

ω = 2×3.14×1046.5

ω = 6572.02

T = sin(6572t)

The sine model for the 64th key on a standard 88-key piano with a frequency of 1046.5 Hz is represented as T(t) = A sin(2π(1046.5)t + φ), where A is the amplitude, φ is the phase shift, and t is the time.

The student has asked for a sine model that represents the Tone, T, as a function of time, t, for the 64th key on a standard 88-key piano, which has a frequency of 1046.5 hertz. A sine function that models the tone can be written as:

T(t) = A sin(2πft + φ)

For this example, since frequency (f) is given as 1046.5 Hz and we don't have information about amplitude (A) and phase shift (φ), we can write the model as:

T(t) = A sin(2π(1046.5)t + φ)

This model can be used by piano tuners to ensure that the piano is properly tuned by comparing the accurate frequency with the sound coming from the piano and making adjustments as needed.
