Step-by-step explanation:

Gary would need 15.2 oz of glue and 7.6 oz of glitter to make 4 bottles.

Option D is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Bottles   Glue   Glitter

1              3.8       1.9

This means,

1 bottle = 3.8 oz of glue and 1.9 oz of glitter

Now,

1 bottle = 3.8 oz of glue

Multiply 4 on both sides.

4 bottle = 4 x 3.8 oz

4 bottle = 15.2 oz

1 bottle = 1.9 oz of glitter

Multiply 4 on both sides.

4 bottle = 7.6 oz

Thus,

15.2 oz of glue and 7.6 oz of glitter to make 4 bottles.

The probability that a random sample of 40 adults would have a mean of at least 7 marshmallows is 0.1943

We know that the formula for the z-score:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

To find: the probability that a random sample of 40 adults would have a mean of at least 7 marshmallows.

This is nothing but the p-value of Z when X = 7

Here the number of marshmallows an adult can fit in their mouth is skewed right with a mean of 6. 5 and a standard deviation of 0. 58

So, mean μ = 6.5

standard deviation σ = 0.58

Also, n = 40,

x = 7,

By central limit theorem,

[tex]z=\frac{x-\mu}{\sigma}\\\\z=\frac{7-6.5}{0.58}\\\\z=\frac{0.5}{0.58}\\\\z = 0.86[/tex]

z = 0.86 has p value 0.1943

Length of side of the rhombus is 5cm.

A rhombus can be thought of as a special parallelogram since it satisfies the requirements for one (a quadrilateral with two pairs of parallel sides). Another characteristic of a rhombus is that it has four equal sides, just like a square. It is also known as a tilted square for this reason.

step1

Diagonals of a rhombus bisect each other at right angles.

Let point of intersection of diagonals be O

So, OD = 3cm , OA = 4cm

From Right angled triangle △ AOD,

⇒ AD²  = OA²  + OD²   (Pythagoras theorem)

⇒ AD² =4² + 3²

⇒ AD² = 16+9

⇒AD² =25

step2

⇒ AD² =25

⇒ AD=5 cm

AD is side of the rhombus.

Answer:

a) The two side lengths of the tenth rectangle in the sequence are 8 + (10 - 1)4 = 32 and 8 + (10 - 2)4 = 28.

b) The area of 576in2 is not possible in the given sequence because it would require a side length of 24, which does not follow the sequence given.

Step-by-step explanation:

The given sequence is represented by the equation an=8+(n−1)4, which means that for each successive rectangle in the sequence, the length of one of the sides will increase by 4. Therefore, in order for the area of a rectangle to be 576in2, the length of one of the sides must be 24, which does not follow the sequence given.

If u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), the derivative of cross product d/dt [u (t) x v (t)] is (3cos(6t) + 3tsin(3t), 2t - 3sin(6t), 3cos(6t) + 3tsin(3t)).

Formula 5 of the cross product theorem states that the derivative of the cross product of two vectors u and v is equal to the cross product of the derivatives of u and v:

d/dt [u(t) x v(t)] = (du/dt) x v(t) + u(t) x (dv/dt)

Where u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), we can find the derivatives as follows:

du/dt = (d(sin 3t)/dt, d(cos 3t)/dt, dt/dt)

= (3 cos 3t, -3 sin 3t, 1)

dv/dt = (dt/dt, d( cos 3t) /dt, d( sin 3t)/dt)

= (1, -3 sin 3t, 3 cos 3t)

Now, we can substitute these derivatives into the formula to find d/dt [u (t) x v (t)]:

d/dt [u(t) x v(t)] = (du/dt) x v(t) + u(t) x (dv/dt) = (3 cos 3t, -3 sin 3t, 1) x (t, cos 3t, sin 3t) + (sin 3t, cos 3t, t) x (1, -3 sin 3t, 3 cos 3t)

= (-3sin²3t - cos3t, t - 3cos3tsin3t, 3cos²3t + 3tsin3t) + (3cos²3t + 3tsin3t, t - 3cos3tsin3t, -3sin²3t - cos3t)

= (3cos²3t + 3tsin3t - 3sin²3t - cos3t, 2t - 6cos3tsin3t, 3cos²3t + 3tsin3t - 3sin²3t - cos3t)

= (3cos(6t) + 3tsin(3t), 2t - 3sin(6t), 3cos(6t) + 3tsin(3t))

The estimated age of the tomb of Sneferu is 8,330 years.

The age of the tomb can be estimated using the carbon-14 decay equation, which states that the amount of carbon-14 remaining after time t (in years) is equal to the initial amount of carbon-14 multiplied by 0.5^(t/5730).The decay equation for carbon-14 is A = A₀e⁻kt, where A₀ is the original amount of carbon-14, A is the amount of carbon-14 at time t, k is the decay constant, and t is the amount of time that has passed.

We can rearrange the equation to solve for t: t = -ln(A/A₀)/k. In this equation, A is the amount of carbon-14 found in the cypress beam, and A₀ is the amount of carbon-14 found in living cypress wood.

In this case, the initial amount of carbon-14 was 100%, and the remaining amount was 55%. Solving for t, we get t = (ln(55%)/ln(0.5))*5730 = 8,330 years.

The weight of a randomly selected pack of gum that has a z-score of 3.11, is 54.6 grams. So, the right option is D.

A Z-score can be used to calculate how much the data deviates from the mean. It shows how frequently the data is either above or below the mean. According to the formula,

Z = (X - μ)/σ

where, Z is the Z-score, X is the data point, μ is the mean and σ is the standard variable.

Z = 3.11, σ = 2.4, μ = 47.1

Z = (X - μ)/σ

Now putting the value

3.11 = (X - 47.1)/2.4

Multiply by 2.4 on both side

X - 47.1 = 3.11 X 2.4

X - 47.1 = 7.464

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The table of input and output values are given for the function.

The slope-intercept form of an equation/function is - y = mx + b

To find the slope m use the formula -

(y2 - y1)/(x2 - x1)

Substituting the values in the equation -

[16 - 32]/[8 - 10]

(-16)/(-2)

8

So, the slope point is obtained as m = 8.

The equation becomes - y = 8x + b

To find the value of b substitute the values of x and y in the equation -

32 = 8(10) + b

32 = 80 + b

b = 32 - 80

b = -48

So, the value for b is -48.

Now, the equation becomes -

y = 8x - 48

A graph has been plotted for the equation.

Similarly, the points for a line is given as (-6,2) and (-9,5).

The slope-intercept form of an equation/function is - y = mx + b

(y2 - y1)/(x2 - x1)

Substituting the values in the equation -

[5 - 2]/[-9 - (-6)]

(3)/(-9 + 6)

3/-3

-1

So, the slope point is obtained as m = -1.

The equation becomes - y = -x + b

To find the value of b substitute the values of x and y in the equation -

2 = -(-6) + b

2 = 6 + b

b = 2 - 6

b = -4

So, the value for b is -4.

Now, the equation becomes -

y = -x - 4

A graph has been plotted for the equation.

It is known that the larger the slope the steeper the line.

Answer:

The equation of a line can be represented in the slope-intercept form, y = mx + b, where m is the slope of the line and b is the y-intercept.

Given that the line has a slope of 5 and passes through the point (-1,1) we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1)

The point (-1,1) can be plugged into the equation:

y - 1 = 5(x + 1)

By simplifying and re-arranging the equation, we get:

y = 5x + 6

So the equation of the line that passes through the point (-1,1) and has a slope of 5 is: y = 5x + 6

Answer:

y = 5x+6

Step-by-step explanation:

Using the slope-intercept form of a line

y = mx+b  where m is the slope and b is the y-intercept

y = 5x+b

Substitute the point into the line.

1 = 5(-1) +b

1+5 = b
