Final answer:

To solve the inequality -4x > -24, divide both sides by -4 and flip the inequality sign to obtain x < 6. The solution in interval notation is (-∞, 6).

Explanation:

To solve the inequality -4x > -24, we can divide both sides of the inequality by -4. Remember, when dividing or multiplying both sides of an inequality by a negative number, the inequality sign flips. So, the inequality becomes:

x < 6

The solution in interval notation is (-∞, 6).

Final answer:

The solution is x < 6, which is represented as (-∞, 6) in interval notation.

Explanation:

To solve the inequality -4x > -24, we can start by dividing both sides by -4.

Divide both sides of the inequality by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.

However, when dividing an inequality by a negative number, the direction of the inequality sign must be flipped. So we have x < 6.

Since the inequality sign is less than, the solution set is all values of x that are less than 6. In interval notation, this is represented as (-∞, 6).

Final answer:

To find the number of blue bags, we calculate based on the 5 to 3 ratio with 10 black bags. Each part corresponds to 2 bags, hence there are 6 blue bags.

Explanation:

The question concerns the calculation of the quantity of blue bags based on a given ratio to the quantity of black bags. If the ratio of black bags to blue bags is 5 to 3, and there are a total of 10 black bags, then we can set up a proportion to find the number of blue bags.

To solve this, we assume the number of black bags (5 parts) equals 10, which means each part corresponds to 10 / 5 = 2 bags. Since there are 3 parts of blue bags in the ratio, we then multiply the number of bags per part by 3 (the number of blue parts), which gives us 3 * 2 = 6 blue bags.

Answer:

y=7x-26

Step-by-step explanation:

A real-world problem using 7 groups can be illustrated like a builder constructing 7 buildings each requiring 15 bricks per day. Multiplying these, 7 times 15 gives us 105, which is the total number of bricks needed each day.

Consider a scenario where a builder is constructing 7 buildings. Each building needs 15 bricks per day for construction. We can therefore write a multiplication problem to find out how many total bricks are needed each day.

So, 7 (groups of buildings) multiplied by 15 (bricks per building) equals a total daily brick requirement. To solve this, you simply multiply 7 by 15 which equals 105 bricks needed each day.

This is a simple real-world problem to help understand the concept of multiplication as repeated addition. Here, you're adding 15 bricks 7 times since there are 7 buildings.

Answer:

sec squared 55 – tan squared 55  = 1

Explanation:

Given, sec square 55 – tan squared 55

We know that,

[tex]\sec \Theta=\frac{\text {hypotenuse}}{\text {base}}[/tex]

And,

[tex]\tan \theta=\frac{\text { perpendicular }}{\text { base }}[/tex]

where Ө is the angle

Substituting the values

[tex]\left(\frac{\text {hypotenuse}}{\text {base}}\right)^{2}-\left(\frac{\text { perpendicular }}{\text {base}}\right)^{2}[/tex]

Solving,

[tex]\frac{(\text {hypotenuse})^{2}-(\text {perpendicular})^{2}}{(\text {base}) *(\text {base})}[/tex]

According to Pythagoras theorem,

[tex]\text { (hypotenuse) }^{2}-\text { (perpendicular) }^{2}=(\text { base })^{2}[/tex]

Putting this in the equation;

squared 55 - tan squared 55 =

[tex]\frac{(\text {hypotenuse})^{2}-(\text {perpendicular})^{2}}{(\text {base}) *(\text {base})}=\frac{(\text {base})^{2}}{(\text {base}) *(\text {base})}=1[/tex]

Therefore, sec squared 55 – tan squared 55 = 1

The value is always 1.

To solve the expression sec²(55°) - tan²(55°), we can use a trigonometric identity. Recall the Pythagorean identity for tangent and secant:

sec²(θ) - tan²(θ) = 1

Using this identity, we substitute θ with 55°:

This simplifies our expression immediately, as the value is always 1 regardless of the angle, as long as the identity holds.

So, sec²(55°) - tan²(55°) = 1.

The missing values are [tex]\( a = 2 \), \( b = 0 \), and \( c = -24 \),[/tex] yielding the factored form [tex]\( 2x(x - 24) \).[/tex]

To find the missing values of[tex]\( a \), \( b \), and \( c \)[/tex], we need to expand the polynomial [tex]\( (x+b)(x+c) \)[/tex]and equate it to [tex]\( 2x^3 - 8x^2 - 24x \).[/tex]

Expanding [tex]\( (x+b)(x+c) \),[/tex] we get:

[tex]\[ (x+b)(x+c) = x^2 + (b+c)x + bc \][/tex]

Comparing this to [tex]\( 2x^3 - 8x^2 - 24x \),[/tex]we see that:

[tex]\[ x^2 + (b+c)x + bc = 2x^3 - 8x^2 - 24x \][/tex]

We need to match the coefficients of corresponding terms on both sides of the equation.

From the equation above, we can equate coefficients:

1. Coefficient of [tex]\( x^3 \): \( 2 = 0 \)[/tex] (there is no [tex]\( x^3 \)[/tex] term on the right side).

2. Coefficient of [tex]\( x^2 \): \( 1 = -8 \) (from \( x^2 \) term)[/tex].

3. Coefficient of [tex]\( x \): \( b + c = -24 \) (from \( x \) term).[/tex]

4. Constant term: [tex]\( bc = 0 \)[/tex] (there is no constant term on the right side).

From the last equation, we know that either [tex]\( b \) or \( c \)[/tex]must be zero, or both.

If one of them is zero, then the other must be equal to [tex]\( -24 \)[/tex] for the equation [tex]\( b + c = -24 \)[/tex] to hold true.

Now, we can test some values to satisfy these equations:

1. If [tex]\( b = 0 \)[/tex]

  [tex]\[ c = -24 \][/tex]

2. If [tex]\( c = 0 \):[/tex]

[tex]\[ b = -24 \][/tex]

3. If both [tex]\( b \) and \( c \)[/tex]are non-zero:

  We can solve the equation [tex]\( b + c = -24 \)[/tex] for various values of [tex]\( b \) and \( c \).[/tex]

Therefore, possible combinations are:

1.[tex]\( a = 2 \), \( b = 0 \), \( c = -24 \)[/tex]

2.[tex]\( a = 2 \), \( b = -24 \), \( c = 0 \)[/tex]

3.[tex]\( a = 2 \), \( b = -12 \), \( c = -12 \)[/tex]

So, the possible missing values are:

1. [tex]\( a = 2 \), \( b = 0 \), \( c = -24 \)[/tex]

2. [tex]\( a = 2 \), \( b = -24 \), \( c = 0 \)[/tex]

3.[tex]\( a = 2 \), \( b = -12 \), \( c = -12 \)[/tex]

[tex]x = 1000[/tex] or [tex]x = 0.01[/tex]

Step-by-step explanation:

We are given a logarithmic equation of x and we have to solve it for x.

Given,

[tex]x^{\log x} = 1000000x[/tex]

⇒ [tex]x^{\log x} = 10^{6} \times x[/tex]

Now, taking log on both sides, we get

[tex]\log x^{\log x} = \log 10^{6} \times x[/tex]

⇒ [tex]\log x .\log x = \log 10^{6}  + \log x[/tex]

{Since [tex]\log a^{b} = b\log a[/tex] and [tex]\log ab = \log a + \log b[/tex]}

⇒ [tex](\log x)^{2} = 6 + \log x[/tex]

{Since log 10 = 1}

⇒ a² = 6 + a {Where, a = log x}

⇒ a² - a - 6 = 0

⇒ (a - 3)(a + 2) = 0

⇒ a = 3 or a = -2

⇒ [tex]\log x = 3[/tex] or [tex]\log x = - 2[/tex]

Now, converting logarithm to exponential form, we get,

⇒ [tex]x = 10^{3} = 1000[/tex] or [tex]x = 10^{- 2} = \frac{1}{100} = 0.01[/tex] (Answer)

So, [tex]x+y =\$200\ \ \ \ equation \ 1[/tex]

Also given;

twice of A's share is less than 3 times than B's share by $20

[tex]2x= 3y -20\\2x-3y = -20 \ \ \ \ equation \ 2[/tex]

Solution:

Now multiplying equation 1 by 3 we get,

[tex]3x+3y=600 \ \ \ \ equation \ 3[/tex]

Now Adding equation 2 and equation 3 we get

[tex](2x-3y = -20)+ (3x+3y=600)\\5x=580\\\\x=\frac{580}{5}=\$116[/tex]

Now Substituting the value of x in equation 1 we get,

[tex]x+y=200\\116+y=200\\y=200-116 = \$84[/tex]

Hence, Share of A is $116 and Share of B is $84.

Answer:

[tex] ME=1.64\sqrt{\frac{0.07(1-0.07)}{370}}=0.0218[/tex]

Step-by-step explanation:

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

[tex]p[/tex] represent the real population proportion of interest

[tex]\hat p=0.07[/tex] represent the estimated proportion for the sample

n=370 is the sample size required (variable of interest)

[tex]z[/tex] represent the critical value for the margin of error

The population proportion have the following distribution  

[tex]p \sim N(p,\sqrt{\frac{\hat p(1-\hat p)}{n}})[/tex]  

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by [tex]\alpha=1-0.90=0.10[/tex] and [tex]\alpha/2 =0.05[/tex]. And the critical value would be given by:  

[tex]z_{\alpha/2}=-1.64, z_{1-\alpha/2}=1.64[/tex]  

The margin of error for the proportion interval is given by this formula:  

[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex] (a)  

And replacing into formula (a) the values provided we got:

[tex] ME=1.64\sqrt{\frac{0.07(1-0.07)}{370}}=0.0218[/tex]

The margin of error on this case would be ME=0.0218
