From the graph, we can see that the graph has bumps on (0,25) and (5.1, -7) coordinates.

The higher point is (0,25) and lower one is at (5.1, -7).

We need to find to find the interval of the local minimum and value of local minimum.

From the graph, we can see that graph has local minimum is -7 in the interval [4,7].

Therefore, correct option is 4th option.

<h3>Over the interval [4,7], the local minimum is -7.</h3>

Madi has $8.80 in pennies and nickels.

shepuryov [24]

Let p = number of pennies.
Let n = number of nickels.

We are given that n= 2p and the total value is $8.80.

We know that a penny = $0.01 and that a nickel = $0.05.

So $0.01p + $0.05n = $8.80.

Substitute 2p for n:
$0.01p + $0.05*2p = $8.80

$0.01p + $0.10p = $8.80

$0.11p = $8.80

p = 80
So n = 2p = 2*80 = 160

Thus there are 80 pennies ($0.8) and 160 nickels ($8.00). The value of all the coins is $8.80.

Ben and Landon took turns driving on their recent 820 mile road trip. Ben averaged 60 miles per hour while landon averaged 56 mi

Furkat [3]

Landon drove for 5 hours.

Step-by-step explanation:

Given that,

Total distance of the road trip = 820 miles

Speed of Ben = 60 miles per hour

Speed of Landon = 56 miles per hour

Step 1 :

Let 'x' be the number of miles Ben drove

Let 'y' be the number of miles Landon drove

Step 2 :

The trip took them 14 hours to complete 820 miles together.

x + y = 14

60x + 56y = 820

Step 3 :

Solve the linear system x+ y= 14 and 60x+ 56y= 820

x + y = 14

x = 14 - y

Step 4 :

Substitute x= 14-y in the second equation,

60(14-y) + 56y = 820

840 - 60y + 56y = 820

Step 5 :

Keeping y terms on one side and constants on other side,

60y - 56y = 840 - 820

4y = 20

y = 20/4

y = 5

Since 'y' is the number of miles Landon drove, the time Landon drove is 5 hours.

Ariana and Emily are both standing in line at Papa Joe’s Pizza. Ariana orders 4 large cheese pizzas and 1 order of breadsticks.

Eva8 [605]

The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50

Elimination method was used.

Step-by-step explanation:

Let,

Cost of one large pizza = x

Cost of one breadstick = y

According to given statement;

4x+y=34.46 Eqn 1

2x+y=18.48 Eqn 2

Subtracting Eqn 2 from Eqn 1

$(4x+y)-(2x+y)=34.46-18.48\\4x+y-2x-y=15.98\\2x=15.98$

Dividing both sides by 2

$\frac{2x}{2}=\frac{15.98}\\x=7.99$

Putting x=7.99 in Eqn 2

$4(7.99)+y=34.46\\31.96+y=34.46\\y=34.46-31.96\\y=2.50$

The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50

Elimination method was used.

At a financial services company, the mean percent allocation for bonds in a retirement portfolio is 26.9 percent with a populati

guajiro [1.7K]

Answer: it is a right tailed probability

Step-by-step explanation:

Population proportion = 26.9/100 = 0.269

We are dealing with the fact that the probability that the mean bond percent for the sample will be at least 28. This means that the sample proportion is 0.28 or above. This means that it is greater than the population proportion of 0.269

The hypothesis would be

For null hypothesis

p = 0.269

For alternative hypothesis,

p > 0.269

The inequality sign means that it is right tailed.
