There is enough data to indicate that Jordanian children are at risk of anemia.

The null hypothesis is that the true mean hemoglobin level for Jordanian children is greater than or equal to 12 g/dl, and the alternative hypothesis is that it is less than 12 g/dl.

Using the P-value method:

The test statistic for the one-sample t-test is given by:

t = (x - μ) / (s / √n)

where x is the sample mean, μ is the population means (here, μ = 12), s is the sample standard deviation, and n is the sample size.

Substitute the given values,

t = (11.3 - 12) / (1.6 / √50) = -2.98

Using a t-distribution table with 49 degrees of freedom (df = n - 1), find that the p-value for this test is approximately 0.002.

Since the p-value is less than the significance level of α = 0.05, we reject the null hypothesis and conclude that there is sufficient evidence to support the claim that Jordanian children are at risk of anemia.

The equation of the straight line shown in the given graph is x = -2

From the question, we are to determine the equation the given straight line in the graph

To determine the equation of the line, we will use the given two points on the line

The given points are (-2, 2) and (-2, -3)

Using the formula,

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

Substitute the given points

(y - 2) / (x - (-2)) = (-3 - 2) / (-2 - (-2))

(y - 2) / (x + 2) = -5 / (-2 + 2)

(y - 2) / (x + 2) = -5 / 0

Cross multiply

0 × (y - 2) = -5 × (x + 2)

0 = -5x - 10

Add 5x to both sides

0 + 5x = -5x + 5x - 10

5x = -10

Divide both sides by 5

5x / 5 = -10/5

x = -2

Hence, the equation is x = -2

Answer:

A. 45(x+3)=60x

Step-by-step explanation:

Tessa's cumulative GPA for all four semesters is 3.44.

To find Tessa's cumulative GPA, we first need to calculate the total number of course units she has taken. For the first three semesters, she took 46 course units. For the fourth semester, she took 12 course units. So, in total, she has taken 46 + 12 = 58 course units.

Next, we need to calculate her total grade points. To do this, we multiply her GPA for each semester by the number of course units she took in that semester, and then add up the results. For the first three semesters, her total grade points are:

3.35 x 46 = 154.1

For the fourth semester, her total grade points are:

3.74 x 12 = 44.88

So her total grade points for all four semesters are:

154.1 + 44.88 = 198.98

Finally, we divide her total grade points by the total number of course units she has taken:

198.98 / 58 = 3.44

Therefore, Tessa's cumulative GPA for all four semesters is 3.44.

Step-by-step explanation:

You want the volume of a rectangular prism that has a base area of 5 1/4 units² and a height of 8 units.

The formula for the volume of a prism is ...

  V = Bh

where B is the base area and h is the height perpendicular to the base.

Here, we have B = 5 1/4 u² and h = 8 u. The volume is ...

  V = (5 1/4 u²)(8 u) = 42 u³

The volume of the prism is 42 cubic units.

Result:

The probability of getting a sum greater than 25 = 1/9.

The answer is not among the given options.

To find the probability, we would need to consider the possible combinations of the spinner and number cube that result in a sum greater than 25.

First, note that the highest possible sum we can get is 12 (that is 6 from the spinner and 6 from the number cube). Therefore, we can remove all combinations that result in a sum of 24 or less.

Next, we can consider the combinations that result in a sum of 25 like this:

Spinner lands on 6, number cube lands on 5

Spinner lands on 5, number cube lands on 6

Spinner lands on 6, number cube lands on 4

Finally, we can consider the combinations that result in a sum greater than 25:

Spinner lands on 5, number cube lands on 5

Spinner lands on 6, number cube lands on 5

Spinner lands on 5, number cube lands on 6

Spinner lands on 6, number cube lands on 6

Here, 4 possible combinations can result in a sum greater than 25 from a total of 6 x 6 = 36 possible outcomes.

So, the probability of getting a sum greater than 25 is 4/36 = 1/9.

Therefore, none of the given answer choices matches this result.

Answer:

Step-by-step explanation:

After 1 half-life, the amount of the element remaining is half of the original amount. After 2 half-lives, the amount remaining is half of the remaining amount after the first half-life. We can continue this pattern until we get to 30 days.

The number of half-lives in 30 days is 30/5 = 6.

So, after 1 half-life, the amount remaining is 948/2 = 474 grams.

After 2 half-lives, the amount remaining is 474/2 = 237 grams.

After 3 half-lives, the amount remaining is 237/2 = 118.5 grams.

After 4 half-lives, the amount remaining is 118.5/2 = 59.25 grams.

After 5 half-lives, the amount remaining is 59.25/2 = 29.625 grams.

After 6 half-lives, the amount remaining is 29.625/2 = 14.8125 grams.

Therefore, after 30 days, 14.8125 grams of the element remains

The answer to the given energy is  5096327.2 J

Remember that Joule is a derived unit of energy which is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one meter

m = 1 tonelada = 1000 kg

h = 500 m

v = 50 km / hr = 13.88 m / s

9 = 10 m / s²

Ep = ?

Ec = ?

The given formula Formula

Ep = m g h = 1000 kg X 10 m / s² X 500 m =  5000000 Joule

Ec = m V² / 2 = 1000 kg X (13.88 m / s)² / 2 = 96327.2 Joule

Et = Ep  +   Ec  =  5000000 J    +   96327.2 J = 5096327.2 J

the y intercept of the linear function in the table is

A linear function is represented using the equation

y = mx + c

the parameters are defined as

y = out put values

m  = slope

x = input variable

c = y - intercept

Solving for slope using values in the table

m = (y2 - y1) / (x2 - x1)

m = (10 - 13) / (4 - 5)

m = -3 / -1

m = 3

Using point slope formula

y - y1 = m(x - x1)

y - 13 = 3(x - 5)

y = 3x - 15 + 13

y = 3x - 2
