What is the value of Z ?

Answers

Answer:

z=130°

Step-by-step explanation:

These are supplementary angles so

z=180-50=130°

Answer:

130

Step-by-step explanation:

That is a straight angle. It has 180 degrees, correct? So you'd have to subtract 180-50 to get your answer of 130.

Katie draws 14 pictures in 24 minutes. At this rate, how many pictures can she draw in 312 minutes?

Answers

Answer:

Hi there! the answer should be: Katie can draw 182 pictures in 312 minutes

Step-by-step explanation:

312 ÷ 24 = 13

14 x 13 = 182

hope this helped qwq

katie can draw 182 pictures in 312 minutes.

first, we should find out how many pictures she can draw in 1 minute. 14/24 equals 0.583333... pictures per minute. 0.583333... times 312 equals 182 pictures (i used a calculator so this should be correct). hope this helps!

Mr. Mendel likes breeding different flowers in his garden. He noticed that when he breeds a white flower with a purple flower, most of the offspring are purple. To check that, he bred them again and obtained 181818 offspring, and 151515 of them were purple. Let's test the hypothesis that the offspring have equal chances of 50\%50%50, percent of being either white or purple versus the alternative that the chance of a purple offspring is greater. The table below sums up the results of 100010001000 simulations, each simulating 181818 offspring with a 50\%50%50, percent chance of being white or purple. According to the simulations, what is the probability of having 151515 purple offspring or more out of 181818? \qquad Let's agree that if the observed outcome has a probability less than 1\%1%1, percent under the tested hypothesis, we will reject the hypothesis. What should we conclude regarding the hypothesis? Choose 1 answer: Choose 1 answer: (Choice A) A We cannot reject the hypothesis. (Choice B) B We should reject the hypothesis. \##\# of purple offspring out of 181818 Frequency 000 000 111 000 222 111 333 333 444 121212 555 333333 666 717171 777 121121121 888 167167167 999 184184184 101010 167167167 111111 121121121 121212 717171 131313 333333 141414 121212 151515 333 161616 111 171717 000 181818 000

What is blended inheritance?

Blended inheritance is a form of inheritance which combines characteristics from both parents. It occurs when the genetic contribution from each parent is not distinct, and instead, the traits of both parents are combined in the offspring. It is also known as "mosaic inheritance" or "mixed inheritance". It can occur in both plants and animals. Blended inheritance is different from Mendelian inheritance, which involves the segregation of individual traits from each parent.

here, we have,

This result showed that the traits for flower color were inherited in a non-blended manner, with one dominant trait (purple flower color) masking the recessive trait (white flower color).This experiment contradicts the idea of blended inheritance, which states that the traits of offspring are a blend of the traits of the parents. Mendel’s experiments showed that traits were passed on in a discrete and non-blended manner, with the dominant trait being fully expressed in the offspring and the recessive trait not being expressed at all.

Therefore, purple flowers are obtained when Mendel cross-pollinated.

There are 6 boys and 8 girls in a classroom. What is the probability that the teacher randomly selects a boy

Answers

Answer:

3/7 is the probability that the teacher will randomly select a boy.

Hope this helps! :)

The probability that the teacher randomly selects a boy is 3/7

How to determine the probability?

The given parameters are:

Boy = 6

Girls = 8

The total number of students is:

Total = 6 + 8 = 14

The probability of selecting a boy is:

P(Boy) = 6/14

Simplify

P(Boy) = 3/7

Hence, the probability that the teacher randomly selects a boy is 3/7

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 30 inches, and the length of the base is 10 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.

Answers

Perimeter = 78.7 inches
Step-by-step explanation:
From the given question, applying the Pythagoras theorem to one of the congruent triangles formed, we have;
= +
= +
=841 + 81
= 922
hyp =
= 30.3645
The perimeter of the triangle can be determined as;
perimeter = + +
= 30.3645 + 18 + 30.3645
= 78.729
The perimeter of the triangle = 78.7 inches

The perimeter of the triangle is 70.82 inches.

Given as :

The length of the altitude is 30 inches, and

The length of the base is 10 inches

What is right triangle?

Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.

Let, perpendicular = 30 and base = 5

According to Pythagoras theorem,

A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

perpendicular² + base² = hypotenuse²

Substitute the values,

30² + 5² =  hypotenuse²

900 + 25 =  hypotenuse² or

hypotenuse² = 925

hypotenuse = √925

hypotenuse = 30.41

The perimeter of the triangle can be determined as:

Perimeter of the triangle = l₁ + l₂ + l₃

Perimeter of the triangle = 30.41+ 10 + 30.41

Perimeter of the triangle = 70.82

Hence, the perimeter of the triangle is 70.82 inches.
