What is 42= -7 × (z - 3)?
Answer:
z=-3
Step-by-step explanation:
Answer:
z=3
Step-by-step explanation:
42=−7(z−3)
Simplify both sides of the equation.
42=−7(z−3)
42=(−7)(z)+(−7)(−3)(Distribute)
42=−7z+21
Flip the equation.
−7z+21=42
Subtract 21 from both sides.
−7z+21−21=42−21
−7z=21
Divide both sides by -7.
-7z/-7=21/7
z=3

you are building a raft out of two by fours. How many two by fours do you need in your raft in order for you to float
Answer: 10 pieces of two by four woods.
Step-by-step explanation:
The number of woods that would be needed depends on the type of design chosen. A more complex design would require more wood to achieve it so it can satisfy the law of buoyancy and float on the water.
10 pieces of two by four would would be enough to build a raft that would float on water.
4. An angle turns through
2/8 of the circle. What is
the measure of
this angle?
Answer:
Teachers already introduce the general concept of revolutions (turns) when they say things like "a full circle is 360°", but they can make the concept more numerically precise by saying "a full turn is 360°, a half turn is 180°, a quarter turn is 90°, and an eighth turn is 45°" or writing "1 rev = 360°, 1/2 rev = 180°, ...

Answer:
An angle that turns through 1 360 of a circle what is the measure in degrees of the angle
Step-by-step explanation:
Angles are typically measured in degrees or radians. Angle measure is based on a circle where a full turn around the circle is 360 degrees. Similarly, a half turn is 180 degrees, a fourth [quarter] turn is 90 degrees, and so on.

1.How do you dilate a figure on the coordinate plane?
2. What is scale factor?
3. What are the properties of similar figures (what do they have congruent and/or proportional)?
Answer:
1. To dilate something in the coordinate plane, multiply each coordinate by the scale factor. This is called mapping. For any dilation the mapping will be \begin{align*}(x, y) \rightarrow (kx, ky)\end{align*}. In this Concept, the center of dilation will always be the origin, unless otherwise stated.
2. When using State Plane coordinates the scale factors, also known as the K factors, are ratios that can be used as multipliers to convert ellipsoidal lengths, also known as geodetic distances, to lengths on the map projection surface, also known as grid distances, and vice versa.
3.Similar figures have the same shape (but not necessarily the same size) and the following properties: Corresponding sides are proportional. That is, the ratios of the corresponding sides are equal. Corresponding angles are equal.

(9 x + 5) - (4 x + 3)
Answer:
this would 5 x + 2
Step-by-step explanation:
Answer: (4x2 + 4x - 5) • (x - 1)
Step-by-step explanation: The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is 5.
The factor(s) are:
of the Leading Coefficient : 1,2 ,4
of the Trailing Constant : 1 ,5
The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms
In our case this means that
4x3-9x+5
can be divided with x-1
2.2 Polynomial Long Division
Dividing : 4x3-9x+5
("Dividend")
By : x-1 ("Divisor")
dividend 4x3 - 9x + 5
- divisor * 4x2 4x3 - 4x2
remainder 4x2 - 9x + 5
- divisor * 4x1 4x2 - 4x
remainder - 5x + 5
- divisor * -5x0 - 5x + 5
remainder 0
Quotient : 4x2+4x-5 Remainder: 0
2.3 Factoring 4x2+4x-5
The first term is, 4x2 its coefficient is 4 .
The middle term is, +4x its coefficient is 4 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 4 • -5 = -20
Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is 4 .
-20 + 1 = -19
-10 + 2 = -8
-5 + 4 = -1
-4 + 5 = 1
-2 + 10 = 8
-1 + 20 = 19
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

What are the slope and y-inyercept of the line 4y=-x-32
First you'll have to bring the equation in form y = mx + b.
4y = -x - 32
y = -1/4 x - 8
So the slope is -1/4 and y-intercept is -8
Hope this helps :)
Questions you may have-
How did you change it to y = mx + b form?
Divide 4 on both sides to isolate the y
Answer:
slope: 1/4
y-intercept: (0,8)

Answer: the value of the diversity index D for the population is 0.42
Step-by-step explanation:
Given that; population of the two species are
p1 = 30% = 0.3 (snapping turtle)
p2 = 70% = 0.7 ( box turtle)
so if two (2) organisms are picked, then they can be different from each other ( i.e Event E) under following two scenarios
E1 → First organism selected from p1 and second organism selected from p2
E2 → First organism selected from p2 and second organism selected from p1
which means we are observing the different orders in which the organisms can be picked.
So the probability of event E = the sum of probabilities of events E1 and E2.
which is;
D = P(E) = P(E1) + P(E2)
= P1×P2 + P2×P1
= 2P1P2
so we substitute
D = 2 × 0.3 × 0.7
D = 0.42
Therefore the value of the diversity index D for the population is 0.42

Suppose that Mudlark decides to sell 140 tickets for this flight. Assuming that all 140 tickets are sold and that the outcome for each ticketholder is independent, how many ticketholders should the airline expect to show up
This question is incomplete, the complete question is;
Lets consider a hypothetical airline, Mudlark Airlines. On one of its flight, previous records show that about 15% of people who had tickets for the flight did not take the flight. There are 120 seats on the plane.
Suppose that Mudlark decides to sell 140 tickets for this flight. Assuming that all 140 tickets are sold and that the outcome for each ticketholder is independent, how many ticketholders should the airline expect to show up
Answer: the airline should expect 119 ticketholders to show up
Step-by-step explanation:
Given that;
the plane contains 120 seats
Their records shows that 15% (0.15) percent of people who previously buy their flight tickets don't show up.
they sold 140 tickets,
Number of ticketholder expected to show up = ?
Probability of showing up for flight will be;
⇒ 1 - 0.15 = 0.85
Now Expected number of ticketholders to shup will be;
⇒ 140 × 0.85
= 119
Therefore the airline should expect 119 ticketholders to show up

For the function f(x) = 2x - 9, find the following
a. f(0)
b. f(2)
c. f(-3)
d. f(1/2)
Answer:
a) f(0) = -9
b) f(2) = -5
c) f(-3) = -15
d) f(1/2)=-8
Step-by-step explanation:
We are given the function [tex]f(x)=2x-9[/tex] and we need to find the following:
a) f(0)
For finding f(0) put x =0 in the given function
[tex]f(x)=2x-9\\Put\:x=0\\f(0)=2(0)-9\\f(0)=-9[/tex]
So, we get f(0)=-9
b) f(2)
For finding f(2) put x =2 in the given function
[tex]f(x)=2x-9\\Put\:x=2\\f(2)=2(2)-9\\f(2)=4-9\\f(2)=-5[/tex]
So, we get f(2)=-5
c) f(-3)
For finding f(-3) put x =-3 in the given function
[tex]f(x)=2x-9\\Put\:x=-3\\f(-3)=2(-3)-9\\f(-3)=-6-9\\f(-3)=-15[/tex]
So, we get f(-3)=-15
d) f(1/2)
For finding f(1/2) put x =1/2 in the given function
[tex]f(x)=2x-9\\Put\:x=\frac{1}{2}\\f(\frac{1}{2})=2(\frac{1}{2})-9\\f(\frac{1}{2})=1-9\\f(\frac{1}{2})=-8[/tex]
So, we get f(1/2)=-8

Consider a binomial experiment with n = 5 trials where the probability of success on a single trial is p = 0.30. (a) Find P(r = 0). (b) Find P(r ≥ 1) by using the complement rule.
Answer:
0.16807 ; 0.83193
Step-by-step explanation:
Given that:
Number of trials, n = 5
Probability of success, p = 0.30
P(r = 0)
Using the binomial probability relation :
P(x =r) = nCr * p^r * (1 - p)^(n - r)
(a) Find P(r = 0).
P(r = 0) = 5C0 * 0.3^0 * (0.7)^(5- 0)
= 1 * 1 * 0.16807
= 0.16807
(b) Find P(r ≥ 1) by using the complement rule
P(r ≥ 1) = 1 - P(r = 0)
P(r ≥ 1) = 1 - 0.16807
P(r ≥ 1) = 0.83193

please solve question in picture branoist to first and correct
Answer:
The correct answer is Option 3: 12y
Step-by-step explanation:
A polynomial term is usually made of a variable and a co-efficient.
Like terms are those terms that have the same variables i.e. x and 44x are like terms.
Given expression is:
[tex]6y-2y+8y[/tex]
All the terms have only y which means that all three terms are alike.
The coefficients of like terms are added or subtracted according to their sign.
[tex]6y-2y+8y[/tex] = 12y
Hence,
The correct answer is Option 3: 12y
