If the probability of picking a red marble out of the total 63 is 8/9, then it's reasonable to think that 8/9 of the total number of marbles must be red. So there are likely 8/9 × 63 = 56 red marbles in the bag.

Answer:

it decreased by 45 degrees f

Step-by-step explanation:

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The change in temperature.

= Final temperature - Initial temperature

The change in temperature is -45°F

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The temperature at the time of bed.

Initial temperature = 36° F

The temperature when she woke up.

Final temperature = -9° F

The change in temperature.

= Final temperature - Initial temperature

= -9 - 36

= 45°F

This means that there was a change of 45°F from the time when she went to bed till the time she woke up.

Thus,

The change in temperature is -45°F

Answer:

-2.154

Step-by-step explanation:

We are given;

Population mean; μ = 432

Sample mean; x¯ = 425

Sample size; n = 29

standard deviation; σ = 26

Hypothesis is defined as;

Null hypothesis; H0: μ ≥ 432

Alternative hypothesis: Ha: μ < 432

Formula for the test statistic since sample size is less than 30 is;

t = (x¯ - μ)/(σ/√n)

Plugging in the relevant values;

t = (425 - 432)/(26/√29)

t = -1.45

Now,we are given significance level of 0.02; our DF = n - 1 = 29 - 1 = 28

From t-table attached, we can see that at DF of 28 and significance value of 0.02, the critical value is 2.154

However, this is a left tailed test as the rejection region is to the left.

Thus, the critical value of a left tailed test is negative. Thus, in this case our critical value will be -2.154

Step-by-step explanation:

two polygons are similar if corresponding angles are congruent and corresponding sides are proportional

If two polygons are SIMILAR, then the corresponding sides must be proportional

The composition of two (or more) isometries is always an isometry

4. A rectangle has a length of 9 mm. A similar rectangle is drawn using a scale of 1:3. What is the length of the second rectangle?

9/1 = 1/3 so 9/3 = 3

Answer:

The answer to the question provided is Grace.

Step-by-step explanation:

The angle measure for 60 degrees and its corresponding side which measures 14 is greater than the measure of 50 degrees and its corresponding side which measures 12.4. That's correct. The reason Hector was incorrect is because the angle measure for 60 degrees and its corresponding side measured 12.4 was less than the measure of 50 degrees and its corresponding side that measured 14. 60 degrees is greater than 50 degrees, then the corresponding side for the angle that measures 60 degrees should be greater than the corresponding side for the angle that measures 50 degrees.

  2.  x ≈ 17.74

  3.  x ≈ 16.64

Step-by-step explanation:

The tangent function relates an angle to the opposite and adjacent sides of a right triangle:

  Tan = Opposite/Adjacent

Here, we're looking for the measure of the side opposite the angle, so we can rearrange this relation to ...

  Opposite = Adjacent×Tan

__

2.  x = 32×tan(29°) ≈ 17.74

3.  x = 13×tan(52°) ≈ 16.64

Step-by-step explanation:

The required, the triangle changes size, but not shape. Option A is correct.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.

Here,
A dilation to place triangle ABC on top of triangle DE is the triangle changes size, but not shape. Because it is necessary property of dilation. Since dilation only helps to scale the figure. In the question it is mention that shifting of triangle through dilation there is why triangle must be scale to shift over one another

Thus, the required, the triangle changes size, but not shape. Option A is correct.

Answer:

Step-by-step explanation:

Because these two triangles are isoceles triangles, two angles are the same, which in this case would be 78. 78 times 2 would give us 156 for the right triangle, but since 180 - 156 does not equal 16, they are not similar nor congruent.

Answer:

h+2h−1000=4400

Step 1: Simplify both sides of the equation.

h+2h−1000=4400

h+2h+−1000=4400

(h+2h)+(−1000)=4400(Combine Like Terms)

3h+−1000=4400

3h−1000=4400

Step 2: Add 1000 to both sides.

3h−1000+1000=4400+1000

3h=5400

Step 3: Divide both sides by 3.

3h3=54003

h=1800

Answer:

h=1800

Answer:

h = 1800

Step-by-step explanation:

Equations

Solve the following equation:

h + (2h - 1000) = 4400

Remove the parentheses. No changes are done because it doesn't have any operation of multiplication or division:

h + 2h - 1000 = 4400

Joining like terms on the left side:

3h - 1000 = 4400

Adding 1000:

3h = 5400

Dividing by 3:

h = 5400/3 = 1800

h = 1800

The simple interest paid to the nearest cent for each principal interest rate and time $1,000, 5%, 2 years is $100.

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.

Simple Interest = (Principal × Rate × Time) / 100

[tex]I = \dfrac{P \times R \times T}{100}[/tex]

Given;

principle= $1000

rate= 5%

time= 2years

Substitute the given values in the formula;

Simple Interest =(1000×5×2)/100

   = 10000/100

Simple Interest will be $100

Applying the logarithmic function, it is found that:

The age of a fossil with a proportion c of carbon 14 remaining is given by:

[tex]t(c) = -3970\ln{c}[/tex]

If the fossil has 47% of carbon-14 remaining, we have that [tex]c = 0.47[/tex], and thus:

[tex]t(0.47) = -3970\ln{0.47} = 2997[/tex]

For a fossil that is 7000 years old, we have that [tex]t(c) = 7000[/tex], and hence:

[tex]t(c) = -3970\ln{c}[/tex]

[tex]\ln{c} = -\frac{3970}{7000}[/tex]

[tex]e^{\ln{c}} = e^{-\frac{3970}{7000}}[/tex]

A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.
