Answer:

8m ×3.5m

Step-by-step explanation:

Area of rectangle= length ×width

Let the length and width of the rectangle be L and W meters respectively.

Area of rectangle= LW

LW= 28 -----(1)

L= 2W +1 -----(2)

Subst. (2) into (1):

(2W +1)(W)= 28

Expand:

2W² +W= 28

-28 on both sides:

2W² +W -28= 0

Factorise:

(W +4)(2W -7)= 0

W +4=0 or 2W -7=0

W= -4 (reject) or W= 3.5

Substitute W= 3.5 into (2):

L= 2(3.5) +1

L= 7 +1

L= 8

∴ The dimensions of the rectangle is 8m ×3.5m.

tan62= 7/25

Step-by-step explanation:

tan = opposite/adjacent

Option A is the correct answer.

We need to find, from the given option which is equivalent to the tangent of 62°.

The ratio of trigonometric function tangent is tanθ=Opposit/Adjacent.

Now, tan62°=24/7.

Therefore, option A is the correct answer.

Answer: D

Step-by-step explanation:

As you can see it is switch from -3 to 3.

Why?

Because each time it is being multiplied by -1 so it switches from negative to positive and geometric sequences involve multiplication (and division so technically it could be dividing by -1).

Answer:

Step-by-step explanation:

take 30 degree as reference angle

using sin rule

sin 30=opposite /hypotenuse

1/2=opposite/2[tex]\sqrt{3[/tex]

opposite=2[tex]\sqrt{3[/tex] /2

opposite=[tex]\sqrt{3[/tex]

Answer:

√3

Step-by-step explanation:

let length of side opposite 30⁰ be x

sin 30= x/ (2√3)

½=x/(2√3)

cross multiply

2x=2√3

x=√3

length opposite 30⁰= √3

Answer:

The null hypothesis is [tex]H_0: p = 0.51[/tex].

The alternate hypothesis is [tex]H_1: p \neq 0.51[/tex].

The p-value of the test is 0.0164 > 0.01, which means that there is not sufficient evidence at the 0.01 level to refute the chief's claim.

Step-by-step explanation:

A local police chief claims that about 51% of all drug related arrests are ever prosecuted

At the null hypothesis, we test if the proportion is of 51%, that is:

[tex]H_0: p = 0.51[/tex]

At the alternate hypothesis, we test if the proportion is different from 51%, that is:

[tex]H_1: p \neq 0.51[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.51 is tested at the null hypothesis:

This means that [tex]\mu = 0.51, \sigma = \sqrt{0.51*0.49}[/tex]

A sample of 900 arrests shows that 47% of the arrests were prosecuted.

This means that [tex]n = 900, X = 0.47[/tex]

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.47 - 0.51}{\frac{\sqrt{0.51*0.49}}{\sqrt{900}}}[/tex]

[tex]z = -2.4[/tex]

P-value of the test:

Probability that the sample proportion differs from 0.51 by at least 0.04, which is P(|z|>2.4), which is 2 multiplied by the p-value of Z = -2.4.

Looking at the z-table, the Z = -2.4 has a p-value of 0.0082.

2*0.0082 = 0.0164.

The p-value of the test is 0.0164 > 0.01, which means that there is not sufficient evidence at the 0.01 level to refute the chief's claim.

Answer:

x = 19

Step-by-step explanation:

Since the angles are vertical, that means these angles are equal to each other:

7x + 34 = 10x - 23

7x - 10x = -23 - 34

-3x = -57

x = 19

Answer:

Step-by-step explanation:

7x+34=10x-23 (being vertically opposite angles)

34+23=10x-7x

57=3x

57/3=x

19=x

Answer:

The probability that x equals 19.62 is 0

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In the normal probability distribution, the probability of an exact value, that is, P(X = x) is 0. Thus, the probability that x equals 19.62 is 0

Answer:

$3089.4

Step-by-step explanation:

A circle is a locus of a point such that its distance from a point known as the center is always constant.

The area of a circle is given by the formula:

Area = πr²; where r is the radius of the circle.

From the image attached, we can see that the garden is circular with a radius of 5.5 yard. Hence:

Amount of mulch needed to cover garden = area of garden = πr² = π(5.5)²  = 95 yd²

Since mulch cost $32.52 per square yard, hence:

Cost of mulch needed = $32.52 per yd² * 95 yd² = $3089.4

Answer:

4-2 = 2

2x5+9 = 19

2^19 = 2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2 = 524288

Answer:

29

Step-by-step explanation:

Use PEMDAS

P- Parenthesis

E- Exponents

M- Multiply

D- Divide

A- Add

S- Subtract

(4-2)^2×5+9 first you do parenthesis which is (4-2)=2

(2)^2×5+9 next the exponents (2)^2=4

4×5+9 now the multiplication, 4×5=20

20+9 And now finish it off with the addition

So the answer ends up being 29.

Answer:

- 4

Step-by-step explanation:

h(x) = sin x

f(x) = | 3x - 4 |

g(x) = 2x² - 6

h( [tex]\frac{\pi }{2}[/tex] ) = sin ( [tex]\frac{\pi }{2}[/tex] ) = 1

f ( 1 ) = | 3 × 1 - 4 | = 1

g ( 1 ) = 2( 1² ) - 6 = - 4

g ( f ( h ( [tex]\frac{\pi }{2}[/tex] ) ) ) = - 4

Answer:

Each girl should sell at least 77 boxes.

Step-by-step explanation:

Considering the number of boxes and how many girls will them, just take [tex]\dfrac{100}{13} \approx 77[/tex]

The exact result is [tex]\dfrac{100}{13} = 76.923...[/tex], but [tex]76 \cdot 13 = 988[/tex] and [tex]77 \cdot 13 = 1001[/tex], therefore, 76 cannot be the result. So, each girl should sell at least 77 boxes.
