Answer:

No, 0.85 is greater.

Step-by-step explanation:

Imagine a number line, with one at the end and 0.1 at the other end. With .85, It would be closer to one, with 0.6 being behind 0.85. The only other reason that 0.6 is greater than 0.85 is if they are converted to fractions.

Answer:

15595 bacteria will be present after 13 hours.

Step-by-step explanation:

Continuous population growth:

The continuous population growth model, for the population after t hours, is given by:

[tex]P(t) = P(0)e^{rt}[/tex]

In which P(0) is the initial population and r is the growth rate.

Started with 5000 bacteria

This means that [tex]P(0) = 5000[/tex]

So

[tex]P(t) = 5000e^{rt}[/tex]

After three hours it grew 6500 bacteria:

This means that [tex]P(3) = 6500[/tex]. We use this to find r.

[tex]P(t) = 5000e^{rt}[/tex]

[tex]6500 = 5000e^{3r}[/tex]

[tex]e^{3r} = \frac{65}{50}[/tex]

[tex]\ln{e^{3r}} = \ln{\frac{65}{50}}[/tex]

[tex]3r = \ln{\frac{65}{50}}[/tex]

[tex]r = \frac{\ln{\frac{65}{50}}}{3}[/tex]

[tex]r = 0.0875[/tex]

So

[tex]P(t) = 5000e^{0.0875t}[/tex]

How many bacteria will be present after 13 hours?

This is P(13). So

[tex]P(13) = 5000e^{0.0875*13} = 15594.8[/tex]

Rounding to the nearest whole number

15595 bacteria will be present after 13 hours.

The answer for this question is A:

A = x = –t + 1 and y = 0.5t + 4 when –2 ≤ t ≤ 6

The parametric equations of the curve are:

x = –t + 1 and y = 0.5t + 4 when –5 ≤ t ≤ 3

The parametric equation of the line is, [tex]x=x_0+at,y=y_0+bt[/tex] where [tex](x_0,y_0)[/tex] is the point on the line and [tex]\frac{b}{a}[/tex] is the slope of the line with a, b are real numbers.

If (a, b) and (c, d) are any two points on the line then, slope of the line is:

m = (d - b)/(c - a)

For given situation,

a line goes from (-5, 7) to (3, 3).

Using the formula of slope, the value of m i.e., slope of the line  would be,

⇒ m = (7 - 3)/(-5 - 3)

⇒ m = 4/(-8)

⇒ m = 1/(-2)

⇒ m= 0.5/(-1)

Comparing with m = b/a,

b = 0.5 and a = -1.

From the graph of the line given below,

A point (1, 4) is also on the line.

Let [tex]\bold{(x_0,y_0)=(1,4)}[/tex]

Using the parametric equation of the line,

[tex]x=x_0+at[/tex]

⇒ x = 1 + (-1)t

⇒ x = -t + 1

and [tex]y = y_0+bt[/tex]

⇒ y = 4 + (0.5)t

⇒ y = 0.5t + 4

Therefore, the parametric equations of the curve are:

x = –t + 1 and y = 0.5t + 4 when –5 ≤ t ≤ 3

Equation Of Line means A straight line on the coordinate plane can be described by the equation. y = mx+b. where m is the slope of the line and b is the intercept.

Answer:Given : points G and I have coordinates (6,4) and (3,2)

To Find : Use  Pythagorean theorem  to calculate the straight line distance between points G and I

Solution:

points G and I have coordinates (6,4) and (3,2)

Draw a line parallel to y axis passing through G

Draw a line parallel to x axis passing through I

Intersection point K ( 6 , 2)

IK = 6 - 3 = 3

GK = 4 -2  = 2

ΔIKG right angled triangle

Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.  

GI² = IK² + GK²

=>  GI²  = 3² + 2²

=>  GI²  = 13

=> GI = √13

using distance formula

G (6,4) and I (3,2)

= √(6 - 3)² + (4 - 2)²

Pyramid formula: V= LWH/3

Step-by-step explanation:

Answer:

336

Step-by-step explanation:

The figure shown is a triangular prism

The volume of a triangular prism can be calculated by using this formula

[tex]V=ah[/tex]

where a = area of base and h = height

we are already given the height ( 8 ft ) so all we need to find is the area of the base

Because this is triangular prism the base will be a triangle

The area of a triangle can be calculated using this formula

[tex]A=\frac{bh}{2}[/tex] where b = base length and h = height

The base length of this particular triangular prism is 12 ft and the height of the base is 7 ft

That being said we plug in the values into the formula

[tex]A=\frac{12*7}{2} \\12*7=84\\\frac{84}{2} =42[/tex]

So we can conclude that the area of the base is 42 ft²

Now to find the volume

Using the formula V = ah

* plug in the values *

V = 42 * 8

42 * 8 = 336

Therefore the volume of the triangular prism is 336ft³

If you are comparing a*b=4*3, a = 4 and b = 3.

This would mean that 2a = 8.

If a×b=2a=b, evaluate 4×3 , Based on the given equation, the result of 4 × 3 is 12.

To evaluate 4 × 3 using the given information, we substitute the values of a and b into the equation.

An equation is a mathematical statement that shows the equality of two expressions or quantities. It consists of an equal sign (=) placed between the two sides of the equation. The expressions on each side of the equal sign are referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation.

Equations are used to represent relationships and solve for unknown values. They can involve variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The goal is to find the value or values of the variable(s) that make the equation true.

Given: a × b = 2a = b

Let's assign a = 4 and b = 3:

4 × 3 = 2(4) = 3

Simplifying the equation:

12 = 8 = 3

Therefore, based on the given equation, the result of 4 × 3 is 12.

Answer:

  yes

Step-by-step explanation:

A negative exponent in the numerator is the same as a positive exponent in the denominator (and vice versa). So, the first two expressions are equivalent.

An exponent is an indication of repeated multiplication. So, the 2nd and 3rd expressions are equivalent.

Any product can be decomposed to a product of its factors. So, the last two expressions are equivalent.

All of the expressions are equivalent.

Answer:

The percentage rate of decay per year is of 5.19%.

The function  showing the mass of the sample remaining after t is [tex]A(t) = 520(0.9481)^t[/tex]

Step-by-step explanation:

Exponential equation of decay:

The exponential equation for the amount of a substance is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial amount and r is the decay rate, as a decimal.

Every 13 years, its mass decreases by half.

This means that [tex]A(13) = 0.5A(0)[/tex]. We use this to find r. So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]0.5A(0) = A(0)(1-r)^{13}[/tex]

[tex](1-r)^{13} = 0.5[/tex]

[tex]\sqrt[13]{(1-r)^{13}} = \sqrt[13]{0.5}[/tex]

[tex]1 - r = (0.5)^\frac{1}{13}[/tex]

[tex]1 - r = 0.9481[/tex]

[tex]r = 1 - 0.9481[/tex]

[tex]r = 0.0519[/tex]

The percentage rate of decay per year is of 5.19%.

The initial mass of a sample of Element X is 520 grams

This means that [tex]A(0) = 520[/tex]. So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]A(t) = 520(1-0.0519)^t[/tex]

[tex]A(t) = 520(0.9481)^t[/tex]

The function  showing the mass of the sample remaining after t is [tex]A(t) = 520(0.9481)^t[/tex]

Answer:

We accept H₀ sample does not give evidence to support that the proportion of Americans who solely use cell phone differs from 23 %

Step-by-step explanation:

A pew research finds  that  23 %  ( μ ) of Americans use only cell phone

Sample Information

sample size   n  = 200

x₁  =  51     then   p₁  = 51/200   p₁  =  0,255

and  q₁  =  1  - p ₁    q₁  =  1  - 0,255    q₁  =  0,745

Sample big enough for the approximation of the binomial distribution to the normal distribution

p₁*n  = 0,255 * 200 = 51  > 5   and   q₁*n    = 0,745* 200 =  149 > 5

Test hypothesis

Null hypothesis                       H₀              p₁  = μ = 0,23

Alternative hypothesis           Hₐ              p₁  ≠  0,23

Is a two tail test. We choose CI = 95 %  then significance level is                    α = 0,05 %

α = 0,05 as is a two tail test   α/2  = 0,025

from z-table  z(c) = 1,96

To calculate  z(s) = ( x  -  μ ) /√p₁*q₁/n  

  z(s) = ( 0,255 - 0,23 )/√0,255*0,745/200

z(s)  =  0,025 / 0,0308

z(s)  = 0,81

Comparing z(s)   and  z(c)

z(s) < z(c)      0,81 < 1,96

Then  z(s) is in the acceptance region: we accept H₀
