The probability of rolling and odd number with both dice A and B is 1/4.

Probability simply means the likelihood that an event will occur on a scenario.

Since Dice A and dice B have ten sides,the numbers will be from 1 to 10. Therefore, there are 5 even numbers and 5 odd numbers.

Probability of odd number = 5/10 = 1/2

Probability of even number = 5/10 = 1/2

Probability of rolling both odd numbers will be:

= P(odd) × P(odd)

= 1/2 × 1/2

= 1/4

The probability is 1/4.

If you double the amount of fluid ounces, the amount of cups also double

There is proportional relationship between the number of fluid ounces and the number of cups. So, the number of cups would change by the same factor as the number of fluid ounces.

The donation is proportional to the dinner bill

The donation for a dinner bill of $50 is $9

If there are 8 fluid ounces in one cup

8 : 1 = 16 : x

8/1 = 16/x

8 × x = 16 × 1

8x = 16

x = 16/8

x = 2

The difference between weight = 1

The difference between cost = $0.68 - $0.47

= $0.21

$0.89 - $0.68

= $0.21

$1.10 - $0.89

= $0.21

Cost of mailing 6-ounce letter

1 : 0.47 = 6 : x

1/0.47 = 6/x

1 × x = 6 × 0.47

x = $2.82

The donation for a dinner bill $50 is

Dinner bill : donation

25 : 4.50 = 50 : x

25/4.50 = 50/x

25 × x = 50 × 4.50

25x = 225

x = 225/25

x =$ 9

Therefore, there is a proportional relationship between two quantities if there is an equal change in the values of both quantities.

The population declines by approximately 2.96% each decade.

To determine the percentage decline of a population each decade, we need to consider the compounding effect of the annual decline over a 10-year period.

Given that the population declines by 0.3% each year, we can calculate the overall decline over a decade as follows:

(1 - 0.003)^10

Using a calculator, we find that (1 - 0.003)^10 ≈ 0.970439.

To express this as a percentage decline, we subtract this value from 1 and multiply by 100:

(1 - 0.970439) * 100 ≈ 2.96.

Therefore, the population declines by approximately 2.96% each decade.

Answer:

============================================

Explanation:

Let's go with the example given to us. Let's say the correct lock combo is 4-2-7.

If we get the first two digits right, then we have 8 choices for the third digit since we pick from between 1 and 8 inclusive. There are 8 combos of the form 4-2-x.

The same goes for stuff of the form 4-x-7 and x-2-7.

There appear to be 8+8+8 = 24 different combos that will open this faulty lock. However, we must subtract off 2 because we've triple counted "4-2-7" when adding up those 8's.

In reality there are 24-2 = 22 different combos that will open the faulty lock.

There are 8^3 = 512 different combos total. That gives 512-22 = 490 combos that do not open the lock.

If the person is very unlucky, with the worst luck possible, then they would randomly try all of the 490 combos that don't work.

Attempt number 491 is when they'll land on one of the 22 combos that do work.

A hypothesis test should be used. Specifically, a one-tailed independent samples t-test is suitable for this purpose.

In a one-tailed test, the hypothesis is formulated with a specific direction, in this case, the expectation that the mean time for non-schizophrenics is less than the mean time for schizophrenics. The null hypothesis (H0) would state that there is no difference or that the mean time for non-schizophrenics is equal to or greater than the mean time for schizophrenics. The alternative hypothesis (Ha) would state that the mean time for non-schizophrenics is less than the mean time for schizophrenics.

The t-test is appropriate because it compares the means of two independent groups (schizophrenics and non-schizophrenics) and determines if the observed difference in means is statistically significant. The t-test takes into account the sample sizes, standard deviations, and the differences between the means to calculate a t-statistic and a p-value. The p-value indicates the likelihood of observing the given difference in means if the null hypothesis were true. If the p-value is sufficiently small (below a predetermined significance level), the null hypothesis is rejected in favor of the alternative hypothesis, supporting the theory that the mean time on the test for non-schizophrenics is less than the mean for schizophrenics.

Answer:

the answer is quartic

Step-by-step explanation:

The fraction  43/25 as a percentage is 34.4%.

To convert a fraction to a percent, we can multiply it by 100.

So, 43/25 as a percent is:

(43/25) x 100 = 172/5 %

We can simplify this fraction by dividing both the numerator and denominator by 5:

172/5 ÷ 5/5 = 34.4 %

One reason for Emma's extreme hunger after working for five straight hours on her psychology paper without eating is that her blood glucose level has dropped. Option C.

Our body's supply of glucose is drained when we participate in lengthy mental or physical activity without eating, which lowers blood sugar levels. The brain receives messages from the stomach-dropping that indicate a need for food.

Emma's body sent hunger signals since the prolonged period of intense work had drained her glucose supplies. Several hormones, notably the appetite-stimulating hormone ghrelin, influence this hungry response. Emma's hunger in this situation is mostly caused by the decline in blood glucose levels.

The slope in a least-squares regression line of the form y = a bx is equal to the coefficient b. This coefficient represents the rate of change in the dependent variable (y) for every one unit increase in the independent variable (x).

Specifically, it represents the change in y divided by the change in x, as b is calculated as the covariance between x and y divided by the variance of x.

This slope is important in understanding the relationship between the variables being studied and can help to make predictions about future values of the dependent variable based on changes in the independent variable.

a) To find a basis for the subspace of all diagonal matrices, we can use the standard basis for 3x3 matrices and select the matrices that have non-zero entries only on the diagonal. Therefore, a basis for this subspace is:

B = {

[1 0 0;

0 0 0;

0 0 0],

[0 0 0;

b) To find a basis for the subspace of all symmetric matrices, we can use the fact that any symmetric matrix can be written as the sum of a diagonal matrix and a skew-symmetric matrix. Therefore, we can take the basis for the subspace of all diagonal matrices found in part (a) and add to it a basis for the subspace of all skew-symmetric matrices, which we will find in part (c).

c) To find a basis for the subspace of all skew-symmetric matrices, we can use the standard basis for 3x3 matrices and select the matrices that satisfy AT = -A. Therefore, a basis for this subspace is:

B = {

Determine x, AB and BC.

Since B is between A and C;

\(AB + BC = AC\)

Substitute x for AB; 2x + 2 for BC and 14 for AC

\(x + 2x + 2 = 14\)

\(3x + 2 = 14\)

The population of the state in 2000 was 24.2 million.

The population of the state will reach 31.4 million in the year 2015 (2000 + 14.5 ≈ 2015).

The population of the state in 2000 was not given directly in the formula. We need to calculate it using the given formula.

Part A:

Let t = 0, as we want to find the population in the year 2000.

A = 24.2e^(0.0775t)

A = 24.2e^(0.0775*0)

A = 24.2e^0

A = 24.2(1)

A = 24.2 million

Therefore, the population of the state in 2000 was 24.2 million.

Part B:

We are given the formula A = 24.2e^(0.0775t) and we want to find the time t when A = 31.4 million.

31.4 = 24.2e^(0.0775t)

e^(0.0775t) = 31.4/24.2

e^(0.0775t) = 1.29752

Take the natural logarithm of both sides:

ln(e^(0.0775t)) = ln(1.29752)

0.0775t = ln(1.29752)

t = ln(1.29752)/0.0775

t ≈ 14.5 years after 2000

Therefore, the population of the state will reach 31.4 million in the year 2015 (2000 + 14.5 ≈ 2015).

Answer:

The point where f(x), g(x), and h(x) have the same value is (8, 11)

Step-by-step explanation:

The points where g(x) and h(x) have the same value is given as follows;

2x - 5 = 8/x + 10

2x² - 15x - 8 = 0

Using an online tool, we have;

(x - 8)(2x + 1) = 0

x = 8 or x = -1/2

∴ g(x) and h(x) = 11 or y = -6

For x = 8, we have;

f(x) = 2^(x - 5) + 3 = 2^(8 - 5) + 3 = 2^3 + 3 = 11

For x = -1/2, we have;

f(x) = 2^(-1/2 - 5) + 3 = 3.022

Therefore, the point where f(x), g(x), and h(x) have the same value is (8, 11), therefore, for x = 8, f(x) = g(x) = h(x) = 11.
