Answer:

B

Step-by-step explanation:

Here, we want to know the kind of relationship a correlation value of 0.45 represents

Generally the perfect correlation value is 1, while a correlation score of zero shows no relationship between the two quantities.

Firstly, the value we have is positive, so we have a positive correlation, since it is closer to zero than 1, we can interpret the value as being a weak positive correlation

Answer:

Step-by-step explanation:

The vertex of a parabola is directly in between the focus and the directrix. That means that the vertex of this parabola is at (1/2, 5). A parabola wraps itself around the focus and away from the directrix, so this parabola opens to the left. One other thing that we need to know is the distance between the vertex and the focus, the p value in the equation. So here's the equation we need (it's not a y= equation, though):

[tex]-(y-k)^2=4p(x-h)[/tex]

So here's what we know from the info above:

p = 5/2

h = 1/2

k = 5

and filling in:

[tex]-(y-5)^2=4(\frac{5}{2})(x-\frac{1}{2})[/tex] and simplifying:

[tex]-(y-5)^2=10(x-\frac{1}{2})[/tex] and then solving for x:

[tex]-\frac{1}{10}(y-5)^2+\frac{1}{2}=x[/tex]

Answer:

Step-by-step explanation:

Given the total God diva chocolate contained in a box to be equal to 52 identical chocolates.

If 31 have caramel filling, the amount of walnut filling will be 52-31 = 21. This means 21 remaining chocolate will contain walnuts.

Probability = expected number of outcomes/total outcome

If we are to find the probability that the chocolate chosen at random contains walnuts, then our expected outcome will be 21 and the total outcome will be total God diva chocolate contained in the box  which is 52.

The probability that the chocolate chosen at random contains walnuts = 21/52

Answer:

Number of pendant made = 10

Step-by-step explanation:

Given:

Sides of triangle = 2 in , 2 in , 1.5 in

Total wire = 5 ft = 5 × 12 = 60 in

Find:

Number of pendant made.

Computation:

Perimeter of 1 pendant = 2 in + 2 in + 1.5 in

Perimeter of 1 pendant = 5.5 in

Number of pendant made = Total wire / Perimeter of 1 pendant

Number of pendant made = 60 / 5.5

Number of pendant made = 10.90

Number of pendant made = 10 and 1 pendant incomplete

Answer:

ii) £120

iii) £2,400

a) 10 workers

c) 4 workers more to be employed.

Step-by-step explanation:

ii) To find the buying price we deduct 20% (percent) from the selling price of £150.

= 20/100 x 150

= £30 (Next we substract this value from the selling price of £150) = €150 - £30 = £120

iii) A 12% interest per annum Implies a 12 percent of the borrowed amount of 20,000, which is calculated as

12% or 12/100 x 20,000 = £2,400

a) Put simply, we create an equation for the problem.

4 men * 10 days = 40 man days.

X men * 4 days = 40 man days.

Let's substitute the equation:

(X/ 4) * (4/ 10) = 40 / 40

(X/4) * 0.4= 1 (collect like terms)

0.4 * x = 4

0.4x/0.4= 4/0.4

x = 10 workers.

(c) 4 extra workers to would need to be employed since we have six already available (10-6=4).

Step-by-step explanation:

You need to Solve for x to find the zeroes of the equation.

x-1=0 So one x is at 1.

x+4=0 So the other x is at -4.

This graph is also not negative so it does not get flipped across the x-axis

The graph of the function [tex]f(x) = (x - 1)(x + 4)[/tex] is graph (d)

The equation of the function is given as:

[tex]f(x) = (x - 1)(x + 4)[/tex]

From the above function, we have the zeros of the function to be:

1 and -4

This means that:

Hence, the graph is graph (d)

Answer:

The slope of new figure A'B'C' = -1.2

A'B' = 3p units

A'C' = 3q units

Step-by-step explanation:

The value of each of the corresponding length of dilated figures (new image) = scale factor multiplied by the corresponding length in original figure.

scale factor = 3

Length of AB = p units

the length of AC = qunits

the length of BC = runits

A'B' = 3p units

A'C' = 3q units

B'C' = 3r units

slope of new figure = slope of previous figure

The slope remains the same = -1.2

The slope of the new figure is mathematically given as

dS=1.2

Question Parameter(s):

The slope of AB is -1.2.

The length of AB is punits

The length of AC is qunits

The length of BC is runits.

Generally, the lengths of the new region are mathematically given as

A'B' = 3p units

A'C' = 3q units

B'C' = 3r units

In conclusion, with the new region consistent in its increase across all regions the slope will remain

dS=1.2

Answer:

H(n) = 234⁽ⁿ⁻¹⁾

Step-by-step explanation:

Hello,

The first thing to do when finding an explicit equation is to determine if the sequence is arithmetic or geometric.

In this question, the sequence is a geometric progression.

h(n) = h⁽ⁿ⁻¹⁾.(-9)

a = -26

r = common difference

a(n) =ar⁽ⁿ⁻¹⁾

h(n) = -26 × (-9)hⁿ⁻¹⁾

h(n) = 234⁽ⁿ⁻¹⁾

2: d. 20x

Step-by-step explanation:

1)

Well to find the volume of a sphere we use the following formula,

[tex]\frac{4}{3}\pi r^3[/tex]

So the radius is 9.

9*9*9 = 729

729*pi = 2290.22104447

So it is 2290 rounded to the nearest whole number.

2290 * 4/3 = 3053.3333333

Thus,

the answer is d. [tex]3054^3[/tex]

____________________________________________________________

So we have to factor 25x^2 - 9,

which is [tex]\left(5x+3\right)\left(5x-3\right)[/tex].

So if the l and w are 5x + 3 and 5x - 3,

= 10x

10x + 10x = 20x,

Thus,

the answer is d. 20x

These are a total of 9 outcomes.

b) What is the probability that Yaniq gets a total of more than 9?

The probability is given by

P = Number of favorable outcomes/Total number of outcomes

For this case, the favorable outcomes are all those outcomes where the total score is more than 9.

Count the number of times Yaniq got a score of more than 9.

Yes right!

2 times (10 and 10)

P(more than 10) = 2/9

c) What is the probability that Yaniq gets a total of less than 7?

For this case, the favorable outcomes are all those outcomes where the total score is less than 7.

Count the number of times Yaniq got a score of less than 7.

Yes right!

Answer: $10.50

Step-by-step explanation:

Given the following :

Number of people entering the park = X

Mean number of people = 3

Fixed admission fee = $6

Additional fee per passenger = $1.50

Therefore, mean total paid by a car entering the park :

MEAN Total = Admission fee + (additional fee * mean number of people entering the park)

mean Total = $6 + ($1.50 * 3)

Mean total = $6 + $4.50 = $10.50

−7q+6+5q=15−7

Step 1: Simplify both sides of the equation.

−7q+6+5q=15−7

−7q+6+5q=15+−7

(−7q+5q)+(6)=(15+−7)(Combine Like Terms)

−2q+6=8

−2q+6=8

Step 2: Subtract 6 from both sides.

−2q+6−6=8−6

−2q=2

Step 3: Divide both sides by -2.

−2q/−2=2/−2

q=−1

p+5+p=3(2+p)

step 1: Simplify both sides of the equation.

p+5+p=3(2+p)

p+5+p=(3)(2)+(3)(p)(Distribute)

p+5+p=6+3p

(p+p)+(5)=3p+6(Combine Like Terms)

2p+5=3p+6

2p+5=3p+6

Step 2: Subtract 3p from both sides.

2p+5−3p=3p+6−3p

−p+5=6

Step 3: Subtract 5 from both sides.

−p+5−5=6−5

−p=1

Step 4: Divide both sides by -1.

−p/−1=1/−1

p=−1

a+4+6a=2(2+3a)

Step 1: Simplify both sides of the equation.

a+4+6a=2(2+3a)

a+4+6a=(2)(2)+(2)(3a)(Distribute)

a+4+6a=4+6a

(a+6a)+(4)=6a+4(Combine Like Terms)

7a+4=6a+4

7a+4=6a+4

Step 2: Subtract 6a from both sides.

7a+4−6a=6a+4−6a

a+4=4

Step 3: Subtract 4 from both sides.

a+4−4=4−4

a=0

Answer:

Option B. 9.11

Step-by-step explanation:

To find the length of line AB, we must first of all calculate the value of θ as shown in the attached photo.

The value of θ can be obtained as follow:

θ + 39° + 120° = 180° (sum of angles in a triangle)

θ + 159° = 180°

Collect like terms

θ = 180° – 159°

θ = 21°

Thus, we can obtain the length of line AB by using sine rule as illustrated below:

b/Sine B = c/Sine C

b = 16

Angle B = 39°

Sine C = 21°

c =?

b/Sine B = c/Sine C

16/Sine 39° = c/Sine 21°

Cross multiply

c × Sine 39° = 16 × Sine 21°

Divide both side by Sine 39°

c = (16 × Sine 21°) / Sine 39°

c = 9.11

Therefore, the length of line AB is 9.11
