Answer:

the value of y is 3 more than twice x

Step-by-step explanation:

we find the slope is 2 because 4/2=2

y=2x+b

we put in the first point (1,5)

5=2+b

b=3

y=2x+3

because 4 times 1 is 4 and if u add 1 than u get 5 which is y

im not sure if this is right lmk

Using the normal distribution, it is found that 66.9% of filled boxes of rice have a weight between 28 and 29 ounces.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

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

In this problem, the mean and the standard deviation are given, respectively, by: [tex]\mu = 28.2, \sigma = 0.4[/tex].

The proportion of filled boxes of rice have a weight between 28 and 29 ounces is the p-value of Z when X = 29 subtracted by the p-value of Z when X = 28, hence:

X = 29:

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

[tex]Z = \frac{29 - 28.2}{0.4}[/tex]

Z = 2

Z = 2 has a p-value of 0.977.

X = 28:

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

[tex]Z = \frac{28 - 28.2}{0.4}[/tex]

Z = -0.5

Z = -0.5 has a p-value of 0.308.

0.977 - 0.308 = 0.669 = 66.9%.

Answer:

x-8 is a factor of f(x)

Step-by-step explanation:

The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).

We are given the function

[tex]f(x)=-2x^3+17x^2-64[/tex]

And it's required to find if x-8 is a factor of f.

Applying the mentioned theorem, we only have to find f(8):

[tex]f(8)=-2\cdot 8^3+17\cdot 8^2-64[/tex]

Operating:

[tex]f(8)=-2\cdot 512+17\cdot 64-64[/tex]

[tex]f(8)=-1024+1088-64[/tex]

[tex]f(8)=0[/tex]

Thus, x-8 is a factor of f(x)

Answer:

0.85 of the original piece of lumber remains.

Step-by-step explanation:

Well, this lumber piece of lumber started as 2.5 meters long. Then, a 1.65 meter piece was cut off of it. All we need to do is subtract.

2.5 - 1.65 =

2.50 - 1.65 = 0.85.

Therefore, 0.85 of the original piece of lumber remains.

Answer:

14 integers

Step-by-step explanation:

Given

[tex]Range: -6.01\ to\ 7.75[/tex]

Required

Determine the number of integers

Integers implies numbers without decimals; it could be positive or negative or 0.

So, within the range: the integers are:

[tex]-6, -5, -4,-3,-2,-1,0,1,2,3,4,5,6,7[/tex]

Notice that the above numbers are integers within the given range.

By counting them, we get the required number of integers.

[tex]Numbers = 14[/tex]

Hence, there are 14 integers

Answer: A) [tex]y=13e^{-0.1359t}[/tex]

              B) H = 5.10

              C) Yes

Step-by-step explanation: Exponential Decay function is a model that describes the reducing of an amount by a constant rate over time. Generally, it is written in the form: [tex]y(t)=Ce^{rt}[/tex]

A) C is initial quantity, in this case, the initial concentration of DDT. To determine r, using the data given:

[tex]y(t)=Ce^{rt}[/tex]

[tex]2.22=13e^{13r}[/tex]

[tex]e^{13r}=0.1708[/tex]

Using a natural logarithm property called power rule:

[tex]13r=ln(0.1708)[/tex]

[tex]r=\frac{ln(0.1708)}{13}[/tex]

[tex]r=-0.1359[/tex]

The decay function for concentration of DDT through the years is [tex]y(t)=13e^{-0.1359t}[/tex]

B) The value of H is calculated by [tex]y=C(0.5)^{\frac{t}{H} }[/tex]

[tex]2.22=13(0.5)^{\frac{13}{H} }[/tex]

[tex](0.5)^{\frac{13}{H} }=0.1708[/tex]

Again, using power rule for logarithm:

[tex]\frac{13}{H} log(0.5)=log(0.1708)[/tex]

[tex]\frac{13}{H} =\frac{log(0.1708)}{log(0.5)}[/tex]

[tex]\frac{13}{H} =2.55[/tex]

H = 5.10

Constant H in the half-life formula is H=5.10

C) Using model [tex]y(t)=13e^{-0.1359t}[/tex] to determine concentration of DDT in 1995:

[tex]y(24)=13e^{-0.1359.24}[/tex]

y(24) = 0.5

By 1995, the concentration of DDT is 0.5 ppm, so using this model is possible to reduce such amount and more of DDT.

Answer:

1. A) OPS is congruent to RSU

2. C) RSP is congruent to TSU

Step-by-step explanation:

1. Since OQ and RT are parallel lines that are cut across by the transversal line, NU, therefore, angle OPS and angle RSU are corresponding angles formed. Corresponding angles are congruent.

✅Therefore: A) OPS is congruent to RSU. OPTION A IS TRUE.

❌OPS and RSP are consecutive interior angles. They are not congruent. They are supplementary. So, option B is NOT TRUE.

❌OPS and OPN are linear pair angles. Linear pair angles are not congruent. They are supplementary. Therefore, OPTION B IS NOT TRUE.

OPS and TSU are also not congruent.

2. Angle RSP and angle RSU are vertical angles. Vertical angles are congruent. Therefore, the statement that IS TRUE is:

C) RSP is congruent to TSU

Answer:

Alice's salary is 1.56 times Wally's salary

Step-by-step explanation:

Let Wally's salary = x

Alice's salary = x + 56% of x

                     = x + 0.56x

                    = 1.56x

                    = 1.56 * Wally's salary

Answer: Additive Inverse of 17 = -17

The two addends in an addition equation are interchangeable, which means that the answer to "What is the additive inverse of -17?" or "What is the additive inverse of negative 17?" is 17. Since the additive inverse of 17 is -17, additive inverse is also known as the opposite number.

Answer:

The circumference of a circle is C = 2πr^2 (2nd power) Radius (r) is the distance from the center of the circle to the outside of it. To find radius divide the diameter (d) by 2. The diameter (d) of a circle is the radius (r) multiplied by 2. To find the diameter (d) you need to do C ÷ π.

For example):

Finding diameter - 76/3.14 = 24.19 (d)

Finding radius - 24.19/2 = 12.095 (r)
