One is one the number line and the 7/10 is between 0.8

IrinaVladis [17]3 years ago

Answer:

Step-by-step explanation:

We are given with a mixed fraction $1\frac{7}{10}$

To solve the given mixed fraction, we will have to split it and perform addition

$1\frac{7}{10} = 1 + \frac{7}{10}$

⇒ $1\frac{7}{10} = \frac{7}{10}$

⇒ $1\frac{7}{10} = 0.7$

now to find $0.7$ , as it is a positive real number, hence it would line to the right of $0$ on the number line between $0$ and $1$

also as the midpoint between $0$ to $1$ will be at $\frac{1}{2}$ or $0.5$ therefore $1\frac{7}{10}$ will be slightly closer to $1$ on the number line.

if Lylah completes the square for f(x)=x squared -12x+7 in order to find the minimum she must write f(x) in the general form f(x

abruzzese [7]

Answer:

A. 6

Step-by-step explanation:

f(x) = x² − 12x + 7

To complete the square, we first factor the leading coefficient to make it 1 (which it already is).

Then, we take half the second coefficient, square it, and then add to both sides. So (-12/2)² = (-6)² = 36.

f(x) + 36 = x² − 12x + 36 + 7

Then we factor the perfect square:

f(x) + 36 = (x − 6)² + 7

Then solve for f(x) by subtracting and simplifying:

f(x) = (x − 6)² + 7 − 36

f(x) = (x − 6)² − 29

So the value of a is 6.

In a box 25 cards are there and 1 to 25 numbers are written on them. one card is drawn randomly. what is the probability that it

tensa zangetsu [6.8K]

Explanation :

Given that:

In a box 25 cards are there and 1 to 25 numbers are written on them.

• One card is drawn randomly.

To Find:

• What is the probability that it is multiple of 5.

We know that:

P(E)= F/T

Where,

P(E)= Probability of an event

• F= Favourable outcomes . T = Total outcomes

We have:

F = Number of cards which are multiple of 5

Cards having the number 5, 10, 15, 20, 25 are the multiples of 5.

So, F = 5

T = Total number of cards

• T = 25

P(F) The probabilityP(E) = The probability that it is multiple of 5

Finding the probability that it is multiple of 5:

P(E)= 5/25

P(E)=1/5

Hence,

The probability that it is multiple of 5 is ⅕

How are integers and rational numbers different

irga5000 [103]

Answer:

An integer is a whole number, positive or negative. A rational number is a number which can be expressed as a fraction between 2 whole numbers. An integer is a rational number, because every integer can be expressed as a fraction between itself and 1, both whole numbers.

Fiona has a box with 5 red buttons and 9 blue buttons.She randomly selected one button, took it out of the box, then selected an

leonid [27]

Answer:

B. 10/91

Step-by-step explanation:

Box has 5 red buttons and 9 blue buttons.

We add 5 and 9 to get the total buttons.

5 + 9 = 14

Then, we find the probability for a red button.

5/14 = .35

Now, that we've taken out 1 button.

The amount of buttons available changes.

14 - 1 = 13

There are 4 red buttons remaining.

The probability for a red button changes to 4/13.

4/13 = .30

Then, we multiply both probabilities.

.30 x .35 = .111

Convert to a fraction.

.111 = 10/91

Thus it would be B.
