Answer:

b) q

c) 7a

d) 2y

Step-by-step explanation:

b) q must be added to p to get p+q

c) 12a-7a = 5a

d) 2y is subtracted from 3x

Answer:

1. q because p+n=p+q, meaning that q would be the answer

2. 7a because is you subtract by 7a from 12a, you get 5a

3. 2y because 3x-n=3x-2y, in which n=2y, which satisfies the equation 3x-2y

Step-by-step explanation:

Choose three intervals on the real number line that contain both rational and irrational numbers. Do you think that any given in

Helen [10]

Any real number line ranges from negative infinity to positive infinity. A real number number line consists of all the rational and irrational numbers. Let us take three intervals which contain both the rational and irrational numbers.

First interval: [3,4]

Since every integer is a rational number, 3 and 4 are both rational. In this interval there occurs the value of π (3.14159..) which is an irrational number.

Second interval : [0,2]

0 and 2 are integers and hence are rational. In this interval, occurs √2 (1.41421...) is an irrational number.

Third interval : [2,3]

In this interval, Eulers number 'e' lie whose value is (2.718281.. )

Hence we can conclude that, there occurs an irrational number between any two rational number.

Y= -4x + 10? What is the slope of the line?

Salsk061 [2.6K]

Answer:

-4 or -4/1

Step-by-step explanation:

The equation is in y=mx+b form

m is the slope, and b is the y intercept

So, for this line, y=-4x+10

-4 is the slope and 10 is the y intercept

Hope this helps! :)

Suppose that in a random selection of 100 colored candies, 26% of them are blue. The candy company claims that the percentage

quester [9]

Answer: a) -0.2252, b) 0.8219

Step-by-step explanation:

Since we have given that

Sample size n = 100

Probability that candies are blue = p= 0.26

Probability that company claims that it is blue candy = P = 0.27

So, Q = 1-P= 1-0.27 = 0.73

So, Null hypothesis : $H_0:p=P$

Alternate hypothesis : $H_1:p\neq P$

So, the test statistic would be

$z=\dfrac{p-P}{\sqrt{\dfrac{P.Q}{n}}}\\\\z=\dfrac{0.26-0.27}{\sqrt{\dfrac{0.27\times 0.73}{100}}}\\\\z=-0.2252$

Since α = 0.05

So, critical value of z = 1.96

p-value = P(Z>Z(calculated)

Using the excel function , we get that

$P(z>0.2252)\\\\=2\times 0.410.911845\\\\=0.8219$

Hence, a) -0.2252, b) 0.8219

the ratio of the angle measures of a triangle are 3:3:4 what angle measures the triangles classification

TEA [102]

Step-by-step explanation:

sum of the ratio=3+3+4=10

now,

angle I = 3/10×180=54

angle II= 3/10×180=54

angle III=4/10×180=72

that shows th given triangle is isoceles
