What is the total length of the tadpoles that are 1/8-inch and 1/4-inch long?
7/8 inches
1 1/8 inches
5/8 inches
3/8 inches
The dot plot shows the frequency or length of the tadpoles
The total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches
How to determine the total length?From the dot plot, we have the following parameters:
3 tadpoles have a length of 1/82 tadpoles have a length of 1/4So, the total length is:
Total = 3 * 1/8 + 2 * 1/4
Evaluate the product
Total = 3/8 + 1/2
Rewrite as;
Total = 3/8 + 4/8
Evaluate the sum
Total = 7/8
Hence, the total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

In some countries, people believe that blood type has a strong impact on personality. For example, Type B blood is thought to be associated with passion and creativity. A statistics student at a large U. S. University decides to test this theory. Reasoning that people involved in the arts should be passionate and creative, she takes a simple random sample of students majoring or minoring in arts at her university and asks them for their blood type. Here are her results:
Observed number of performing arts majors with each blood type
Type A Type B Type AB Type 0 Total
50 23 10 67 150
Assume the distribution of blood type among all U. S. Residents is as follows:
Type A: 42%; Type B: 10%; Type AB: 4%; Type O: 44%.
(a) The student wants to carry out a test of significance to see if the distribution of blood types among arts majors or minors is different from the U. S. Distribution. State the null and alternative hypotheses for this test.
(b) Find the expected counts for each blood type under the assumption that the null hypothesis is true.
(c) Discuss whether the conditions for this test have been met.
(d) Find the value of the test statistic and the P-value of the test, and make the appropriate conclusion. Use α = 0. 5.
(e) Based on your answer to (d), which error is it possible that you have made, Type I or Type II? Describe that error in the context of the problem
The null hypothesis for the test regarding the blood type is that they distribution of blood types among art major is the same as the US distribution.
What is a null hypothesis?It should be noted that null hypothesis simply suggests that there is no statistical relationship.
Here, the null hypothesis for the test regarding the blood type is that the distribution of blood types among art major is the same as the US distribution and the alternative hypothesis is that the distribution of blood types among art major is different from the US distribution.
The conditions for this test have been met as all expected frequencies are greater than 5.
Since the test statistic is 9.63 and the p-value is 0.022, one can reject the null hypothesis. Therefore, it'll be concluded that the distribution of blood types among arts majors and minors is different from the U.S distribution.

Step-by-step explanation: i did the math
i divided 57 by 3 and it was 19 thats the amount of bxes per min then i multipyed by 25
Answer:
475
Step-by-step explanation:
In 1 minute It makes:
57/3 = 19
In 25 minutes It makes:
25 * 19 = 475
Write (5i)2 as either an integer
or an integer multiple of I
[tex](5i)^2\\\\=25\cdot i^2\\\\=25(-1)\\\\=-25[/tex]
(5i)² can be written in integer form as as -25.
What is a Complex number?The numbers which can be expressed in the form of a + ib, where both 'a' and 'b' are real numbers and 'i' an imaginary number is called complex numbers.
So a complex number has a real part and an imaginary part.
The imaginary number 'i' is called iota and value of i is √-1.
We know the value of i.
i = √-1
i² = -1
(5i)² only has an imaginary part.
∴ (5i)² = 5² i²
= 25 × -1
= -25
Hence we can write (5i)² as -25 in the integer form.

Find the nature of the roots of 4x ^ 2 + 6x - 7 = 0
a. complex
b. irrational
c. rational
d. real and equal
Answer:
b
Step-by-step explanation:
given a quadratic equation in standard form
ax² + bx + c = 0 (a ≠ 0 )
the discriminant b² - 4ac informs us about the nature of the roots
• If b² - 4ac > 0 then roots are real and irrational
• If b² - 4ac > 0 abd a perfect square then roots are real and rational
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 the roots are complex
4x² + 6x - 7 = 0 ← is in standard form
with a = 4, b = 6, c = - 7 , then
b² - 4ac = 6² - (4 × 4 × - 7) = 36 - (- 112) = 36 + 112 = 148
since b² - 4ac > 0 then roots are real and irrational
