[tex]\begin{array}{rcl}A & = & \dfrac{1}{2}(a + b)h\\\\& = & \dfrac{1}{2}(3.8 + 2.6)\times 4\\\\& = & \dfrac{1}{2}(6.4) \times 4\\\\A & = & \dfrac{1}{2}\times25.6\\\\& = & \textbf{12.8 m}^{\mathbf{2}}\\\end{array}\\\text{The area of the room is $\large \boxed{\textbf{12.8 m}^{\mathbf{2}}}$}[/tex]

Answer:

-19

Step-by-step explanation:

12x - 6 + 6 = 10x - 40 + 2

12x - 10x = -40 + 2 + 6 -6

2x = -38

x = -38/2 = -19

The two truths are:

x is a negative number (x = -19)

x+5>x (if x is positive, is true; if x is negative, is also true)

The one lie is:

3x > 2x (if x is negative, the expression will be 3x < 2x)

Answer:

Step-by-step explanation:

It is convenient to compute the areas in terms of grid squares. Then those results can be converted to square meters by multiplying by the area of a grid square: (10 m)² = 100 m².

(a) The area of the school is the product of its side dimensions. The short side is (in terms of grid squares) ...

 W = √(1²+3²) = √10

The long side is ...

  L = √(2²+6²) = √40

Then the area is ...

  A = LW = (√40)(√10) = √400 = 20

The area of the school is 20 grid squares = 2000 m² . . . . . where s = 10 m

__

(b) The area of the museum is given by the formula ...

  A = πr² = π(3)² = 9π grid squares = 2827 m²

The area of the museum is 2827 m².

__

(c) Marci says the museum has a larger area than the school. She is correct.

Marci should win the debate.

Pounds of water = 39

Pounds of brick dust = 48

Total mixture = 87 pounds

Mixture spilled = 13 pounds

Mixture remaining = 87 pounds - 13 pounds

= 74 pounds

Mixture in each brick holes = 7 pounds of mixture

Greatest number of bricks Lynn can make = Mixture remaining ÷ Mixture in each brick holes

Answer:

The discriminant of the equation is less than zero. The gymnast's hands do not reach a height of 11 feet

Step-by-step explanation:

The gymnast's hands does not reach a height of 11 feet above the trampoline.

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is a[tex]x^{2}[/tex] + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.

It is given that ,

h= [tex]-16x^{2} +12x[/tex]

11-6= [tex]-16x^{2} +12x[/tex]

5 = [tex]-16x^{2} +12x[/tex]

[tex]-16x^{2} +12x[/tex] -5=0

Comparing the above equation with the standard form of quadratic equation [tex]ax^{2} +bx+c=0\\[/tex]

we get ; a=-16, b=12, c=-5

Using Discriminant method

D= [tex]\sqrt[]{b^{2} - 4*a*c}[/tex]

  = [tex]\sqrt[]{(12)^{2} - 4* (-16)*(-5)}[/tex]

  = [tex]\sqrt[]{144-320}[/tex]

  = [tex]\sqrt[]{-176}[/tex]

Hence D<0, which means there is no real value.

So, the gymnast's hands does not reach a height of 11 feet above the trampoline.

Answer:

20 cm

Step-by-step explanation:

Area of a triangle is base x height/2, so in this case its 5x8/2 which is 40/2 therefor making the answer 20

The original translation < 3, -3 > moves the figure 3 units to the right and 3 units down.

We undo this by moving 3 units left and 3 units up, which is what < -3, 3 > describes.

The translation <-3, 3> will move the image back to the preimage original position.

The displacement of a image from one place to another is called translation of image.

If a figure is on the origin, i.e. (0, 0), then if turns 3 cells right.

We can see that, It translated as (3,0)

Again if it go down 3 cells, then the translated one is (3, -3)

So, moving it back, we should translate it 3 cells left & 3 cells up.

So after translation, it should be (-3, 3).

Answer:

Sin theta = -1/2

Step-by-step explanation:

pi < =theta <= (3pi)/2.

The above expression shows we are dealing with angle on the 3rd quadrant.

I.e greater than 180 but less than 270.

So sin tita = (√3)/2

But sin and cos are all negative in the third quadrant.

So tita = sin^-1(√3)/2

tita = 60°

Cos tita = cos 60

Cos tita = cos 60

Cos60 = 0.5

Cos 60 = 1/2

If

sin theta = -(sqrt(3))/2

Sin theta = -1/2

Answer:

Step-by-step explanation:

Given that:

A study is conducted and the study by Consumer Reports showed that 64% of supermarket shoppers believe supermarket brands to be as good as national name brands.

a)

Thus; we formulate the null and the alternative hypotheses as follows:

The proportion is ; [tex]\frac{64}{100}[/tex] = 0.64

Null hypothesis:    [tex]{H_0}:p = 0.64[/tex]  

The Null hypothesis states that there is no evidence that “the percentage of supermarket shoppers believes that the supermarket ketchup is good as the national brand ketchup differ form 64%”.

Alternative hypothesis: [tex]{H_a}:p \ne 0.64H[/tex]

The Alternative hypothesis states that there is evidence that “the percentage of supermarket shoppers believes that the supermarket ketchup is good as the national brand ketchup differ form 64%”.

b)

The proportion of the population = 0.64

The sample size n = 100

The number of shoppers = 52  stating that the supermarket brand was as good as the national brand

The sample proportion [tex]\hat p = \frac{52}{100}[/tex]

[tex]\hat p = 0.52[/tex]

The z - value is calculated by the formula:

[tex]z = \dfrac{\hat p-p}{\frac{\sqrt{ p(1-p)}}{100 }}[/tex]

[tex]z = \dfrac{0.52-0.64}{\frac{\sqrt{ 0.64(1-0.64)}}{100 }}[/tex]

[tex]z = \dfrac{-0.12}{0.048 }}[/tex]

z = -2.50

Since z = -2.50

the p-value = 2P(Z ≤ -2.50)

p-value = 2 × 0.0062

The p-value = 0.0124

c)

At  significance level,  ∝ = 0.05 ; The p-value = 0.0124

According to  the rejection rule, if p-value is less than 0.05 then we will reject null hypothesis at ∝ = 0.05

Hence, the p-value =0.0124 < ∝ (=0.05)

According to the reject rule; reject null hypothesis.

Conclusion: There is no evidence at all that the percentage of supermarket shoppers believes that the supermarket ketchup is good as the national brand ketchup differ form 64%.

d) we know that the significance level of ∝  = 0.05

The value[tex]{z__{0.05}}[/tex]  is obtained as:

[tex]P\left( {\left| Z \right| \le z} \right) = 0.05[/tex]

Now; to determine Z ; we locate the probability value of 0.05 form the table of standard normal distribution. Then we proceed to the left until the  first column is reached and  the value is 1.90. Also , we move upward until we reach the top and the value is 0.06. Now; the intersection of the row and column results the area  to the left of z

This implies that :[tex]P(Z \leq -1.96)=0.05[/tex]

The critical value for left tail is -1.96 and the critical value for right tail is 1.96.

Conclusion:

The critical value is -1.96 and the value of test statistic is - 2.50.  Here, we can see that  the value of test statistic is lesser than the critical value. Hence, we can be concluded that there is evidence that reject the null hypothesis.

Therefore, Yes, the national brand ketchup manufacturer is pleased with the conclusion.

Following are the solution to the given points:

For point a:

Calculation of the hypotheses:

Null hypothesis [tex]\ H_0:p=0.64 \\\\[/tex]

Alternative hypothesis [tex]\ H_a : p \neq 0.64[/tex]

For point b:

 Checking the value:  

[tex]\to np_0=100 \cdot 0.64=64>5\\\\\to n(1-p_0)=100\cdot(1-0.64)=100 \cdot 0.36= 36 > 5[/tex]

Test statistic:

[tex]\to Z= \frac{0.52-0.64}{\sqrt{\frac{0.64 \times 0.36}{100} }}=-2.50[/tex]

Since there are two-sided for the test. so, [tex]z=-2.50[/tex] is negative.

Calculation of the P-value:  [tex]\to p=2P(z \leq -2.50)=2 \cdot 0.00621=0.01242<\alpha =0.05[/tex]

For point C:

In this choice, the Null hypothesis value should be rejected.

⁴√x⁴√x = x1/4x1/4 = x1/4+1/4

=⁴√5⁴√2⁴x1/4+1/4

1/4+1/4 = 1/2

Answer:

g(x) = 4x - 1

Step-by-step explanation:

Linear function in the format: g(x) = ax + b

g(2t) is a*(2t)+b

g(2t) = 8t - 1 means that:

when x = 2t, g = 8t - 1.

So

Equaling both sides

8t - 1 = a*2t + b

So

b = -1,

and

2a = 8, a = 8/2, a = 4

So

g(x) = 4x - 1
