The element in group 15 and period 4

Answers

Answer 1

Answer:

Final answer:

The element in group 15 and period 4 of the periodic table is Arsenic (As), which is classified as a metalloid due to its mixed properties of metals and non-metals.

Explanation:

The element that is found in group 15 and period 4 on the periodic table is Arsenic (As). Group refers to the vertical column and period refers to the horizontal row on the periodic table.

Arsenic belongs to the 'p-block' group of the periodic table and it is classified as a metalloid. This means it has properties of both metals and non-metals. For example, arsenic is brittle (like a non-metal) but can also conduct some electricity (like a metal).

What type of triangle is formed by joining the points D(7, 3), E(8, 1), and F(4, -1)?

Answers

$D(7,3) \nE(8,1) \nF(4,-1)$

The lengths of the sides of the triangle:
$\overline{DE}=√((8-7)^2+(1-3)^2)=√(1^2+(-2)^2)=√(1+4)=√(5) \n \n\overline{DF}=√((4-7)^2+(-1-3)^2)=√((-3)^2+(-4)^2)=√(9+16)=√(25)=5 \n \n\overline{EF}=√((4-8)^2+(-1-1)^2)=√((-4)^2+(-2)^2)=√(16+4)=√(20)= \n=√(4 * 5)=2√(5)$

No sides are equal to each other, so it's a scalene triangle.

Check if the sides satisfy the Pythagorean theorem:
$(√(5))^2 + (2√(5))^2=5^2 \n5+20=25 \n25=25 \ntrue$
They do, so it's a right triangle.

The triangle is a right scalene triangle.

Have a nice day :)

Noah is studying dogs to determine their interest in blue toys versus red toys. He splits a group of 20 dogs into 2 groups. One group is given blue toys and the other is given red toys. Noah has the dogs play with the toys until they lose interest. He finds that the dogs that had blue toys played with them 2 minutes longer than the dogs that played with red toys. Noah rerandomizes the data, calculates the difference between the means, and creates the dot plot shown below. Based on the data, can Noah conclude the difference is significant?.

Answers

Noah re randomizes the data, calculates the difference between the means, and creates the dot plot shown below. Based on the data, can Noah conclude the difference is significant?

Answer: by looking at the graph we can make the conclusion that Yes, Noah can conclude the difference is significant because a 2-minute difference is not likely to happen by chance. Please see the graph in the attachments.

I hope it helps, Regards.

We have to determine conclude the difference is significant.

What is the difference?

The difference is a key concept of philosophy, denoting the process or set of properties by which one entity is distinguished from another within a relational field or a given conceptual system.

By looking at the graph we can make the conclusion that Yes, Noah can conclude the difference is significant because a 2-minute difference is not likely to happen by chance. Please see the graph in the attachments.

5 t-shirts and a hat costs £27.00 2 t-shirts and a hat costs £12.00.
How much does a t-shirt cost?
How much does a hat cost?

Answers

Answer:

£2

Step-by-step explanation:

Let T represent T-shirt and H represent hat

5T + H = £27.00

2T + H = £12.00 Subtract two equation

5T + H - 2T - H = £27 - £12 ➡ 3T = £15 and T = £5 this is the cost for a t-shirt

If a t-shirt costs £5 and 2 t-shirt + a hat costs £12 then a hat costs £2

Let say that t-shirt is X and hat is Y
We get: 5X+Y=27.00
2X+Y=12.00
solve for X in the first equation
5X+Y= 27
5X=27-Y
X=27-Y/5
Replace X= 27-Y/5 in equation 1 or 2
I use equation 2:
2*27-Y/5+Y=12
54-2Y/5+Y=12
make the denominator equal
54-2Y/5+5Y/5=12
54+3Y/5=12
Multiply 5 both side
54+3Y = 60
3Y = 60-54
3Y= 6
Y=6/3
Y=2
Replace Y= 2 in equation 1 or 2
I use 2:
2X+2=12
2X=10
X=5
Thus the answer is T-shirt cost : £5 and hat cost : £2
