what does a negative sign in front of a parentheses meanif you have -(1/6)(-4/9) how do you solve?

The probability that Joe will pass the test is 100%.

From the information, Joe hasn't studied for the final test in his statistics class, but he does have some background, so he's sure he can get the right answer about 60% of the time.

Therefore, if there are 100 multiple choice questions, and the lowest passing score is 60%, the probability that Joe will pass is 100%. This is because he usually has a 60% passing rate and this tallies with the lowest percentage needed to pass.

Answer:

49*0.53=25.97 :)

(edited) ;)

Step-by-step explanation:

53 percent of 49 is approximately equal to 25.97.  the correct answer is option B) 25.97.

To find 53 percent of 49, we can calculate it by multiplying 49 by 0.53 (which is equivalent to 53 divided by 100).

49 * 0.53 = 25.97

Therefore, 53 percent of 49 is approximately equal to 25.97.

So, the correct answer is option B) 25.97.

Options A) 2.597, C) 259.7, and D) 2,597 are not correct since they either incorrectly place the decimal point or exaggerate the value by orders of magnitude. The accurate value is 25.97.

Answer:

A. 10x + y - 2 Ans

B. Solution

(3x + 4) + (y - 5) + ( 7x - 1) =0

grouping

(3x + 7x) + (y) + (4 - 5 - 1) =0

10x + y -2 =0

therefore

perimeter is 10x + y - 2

Based on the given histogram, the data is skewed with a maximum range of 49.

This is because the frequency bars are not evenly distributed across the x-axis intervals, indicating that the data is not symmetric. The lack of a shaded bar for the 40 to 49 interval also suggests that there were fewer donations in that range compared to the other intervals.

One possible explanation for this skewness could be that the charity had suggested donation levels, with a minimum of $10, resulting in a large number of donations in the 10 to 19 interval. Additionally, the shaded bar stopping at 1 for the 30 to 39 and 50 to 59 intervals suggests that there were fewer donations in those ranges. This could be due to a variety of reasons, such as donors being more likely to give in the suggested $10 increments, or the charity's fundraising efforts being more effective at attracting donors in certain age or income brackets.

Overall, the histogram does not suggest a bimodal distribution, as there is not a clear separation between two distinct modes. The maximum range of 49 also indicates that there were no extreme outliers or large donations that would skew the data towards a higher range. Therefore, it is likely that the data represents a typical distribution of donations to a charity, with most donors giving smaller amounts and fewer donors giving larger amounts.

We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot.

A statistical test is required to determine whether the length of the left foot is greater than the length of the right foot. The null hypothesis states that there is no difference in average length between the left and right feet. The alternative hypothesis is that the left foot's average length is greater than the right foot's average length.

This hypothesis is one-tailed, as we are only interested in whether the left foot is longer than the right foot. We are not considering the possibility that the right foot could be longer than the left foot.

A t-test can be used to determine whether the difference in average length between the left and right feet is statistically significant. We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot if the p-value of the t-test is less than the chosen significance level (e.g., 0.05).

The block's density can be calculated using the equation d=25g/8.4 cm.

Two things are equal, according to an equation.

For instance, 10 + 2 equals 6 + 6.

Simply put, this means that 10 plus 2 equals or is the same as 6 plus 6.

In an equation, the unknown could be present, as in 10 + x = 6 + 6.

So, find the block's volume first:

= Length * Width * Height

= 2 x 3 x 1.4

= 8.4 cm

Now that you know the volume and the mass, you can add them to the density formula, which is as follows:

= Mass / Volume

Assuming density is represented by the symbol b, the formula would be:

d = 25 g / 8.4 cm

Therefore, the block's density can be calculated using the equation d=25g/8.4 cm.

Step-by-step explanation:

The graph of f(x) relate to its parent function by B. The parent function has been translated up.

Given that

f(x) = 3x +2 +4

When evaluated, we have

f(x) = 3x + 6

The parent function of the above is

f(x) = 3x

When f(x) = 3x is compared to f(x) = 3x + 6, we have

Difference = 6

Answer is \(2\sqrt{2}\) mi

Given,

Kaylib’s eye-level height is 48 ft

Addison’s eye-level height is 85 and one-third ft above sea level.

From the formula d= \(\sqrt{3h/2}\),

get the difference as:

\(d=\sqrt{(3*(85+1/3))/2} - \sqrt{(3*48)/2}\)

=\(\sqrt{256/2} - \sqrt{3*24}\)

=\(\sqrt{128} - 6\sqrt{2}\)

The denominator is zero (0/0 is undefined), we cannot determine the exact value of f(-3) using this equation.

To solve the given equations, we need to find the value of the function f(x) for specific values of x.

"If f(x) / (x - 2) = x³ + 2x - 4 + 13/(x - 2), what is f(2)?"

To find f(2), we can substitute x = 2 into the equation and solve for f(2).

Plugging in x = 2, we get:

f(2) / (2 - 2) = 2³ + 2(2) - 4 + 13/(2 - 2)

Since the denominator is zero (2 - 2 = 0), the equation is undefined. Therefore, there is no solution for f(2) in this case.

"If f(x) / (x + 3) = 3x² - 4x + 2, what is f(-3)?"

To find f(-3), we can substitute x = -3 into the equation and solve for f(-3).

Plugging in x = -3, we get:

f(-3) / (-3 + 3) = 3(-3)² - 4(-3) + 2

Simplifying, we have:

f(-3) / 0 = 3(9) + 12 + 2

f(-3) / 0 = 27 + 12 + 2

f(-3) / 0 = 41

Additional information or context is needed to solve for f(-3).
